Write the number using words.

Question 3.
562
Answer: Five hundred sixty-two
Explanation:

Note: Learn to write numbers from 1 to 9. This is where it all starts. Learn these, and the rest gets much easier:
1. Understanding the place values: We can tell what each digit in a number means based on where it is.
2. Write the last two digits at the end of the number. This part is just like writing a normal two-digit number.
– 562: Start with just the 62 at the end. Write this as sixty-two
3. Write the hundreds place. The next digit is the hundreds place. This is an easy one. Just write the number in that place, then add the word “hundred.” Write this in front of your number.
– In 506, the 5 is in the hundreds place. Write this as five hundred.
4. Now we have five hundred sixty-two.

Question 4.
Draw and label points to show where 25 and 61 belong. (TEKS 2.2.E)

Draw quick pictures to solve the problems. Then complete the sentences.
More ____________ were at the zoo.
Fewer ____________ were at the park.

FOR THE TEACHER: Read the following problem and have children draw quick pictures to compare the numbers. There were 82 butterflies and 86 birds at the zoo. Were there more butterflies or more birds? Repeat for the following problem: There were 47 water fountains at the park and 92 benches at the park. Were there fewer benches or fewer water fountains?
Answer:
More birds were at the zoo
Fewer water fountains at the park.
Explanation:
The number of butterflies at the zoo=82
The number of birds at the zoo=86
Now comparing the butterflies and birds each other:
When we have two numbers or quantities to compare, then we use three basic symbols, they are:
1. Equal to (=)
2. Greater than symbol (>)
3. less than symbol (<).
Birds are greater than butterflies.
Birds < butterflies.
Therefore, more birds are there in a zoo compared to butterflies.
The number of water fountains in a park=47
The number of benches at the park=92
Now comparing both;
water fountains are lesser than benches.
water fountains<benches.

Mathematical Processes

Explain how you compared the numbers in the first problem.
Answer:
For comparing numbers there are some basic rules we need to learn:
When we have two numbers or quantities to compare, then we use three basic symbols, they are:
1. Equal to (=)
2. Greater than symbol (>)
3. less than symbol (<).
Here we need to compare the numbers. There are certain rules, based on which it becomes easier to compare numbers. These rules are:
– Numbers with more digits
– Numbers starting with a larger digit
Rule 1: Number with more digits
When we compare numbers, then check if both the numbers are having the same number of digits or not. If a number has more digits, then it is greater than the other number.
For example:
– Two-digit numbers are greater than single-digit numbers
– Three-digit numbers are greater than two-digit numbers and so on…
Rule 2: Numbers starting with a greater digit
This rule is applicable when two numbers are having the same number of digits. In such cases, we need to check the digit at the leftmost place, whichever is greater. Therefore, the number with a greater digit at the leftmost place of the number is greater than the other number.
For example, take the number of birds and butterflies.
birds=86
butterflies=82
86>82 [ 86 is greater than 82]
82<86 [82 is less than 86]
Thus, in the above examples, we can see that, when we compare the two numbers, though the number of digits is the same, one number is greater than/less than the other number.
This is how we differentiate and compare the numbers.

Model and Draw

Use place value to compare numbers. Start by looking at the digits in the greatest place value position first.

Answer:

Explanation:
Here we need to compare the place values:
In the first diagram,
there are two numbers: 483 and 570
In the number 483,
4 is in the hundreds place
8 is in the tens place
3 is in the one’s place.
In the number 570,
5 is in the hundreds place
7 is in the tens place
0 is in the ones.
Now compare all the places:
First, compare the hundreds of places:
In the hundreds place, 4 and 5 numbers are there:
4 is less than the 5 (4<5)
Now compare tens place :
In the tens place, 8 and 7 are there:
8 is greater than the 7 (8>7)
In the one’s place, 3 and 0 are there:
3 is greater than 0 (3>0).
Likewise, we need to write for 352 and 346.
Compare hundreds, tens and ones place.
3 and 3 are equal (3=3)
5 and 4: 5 is greater than 4 (5>4)
2 and 6: 2 is less than 6 (2>6)

Question 1.

Answer: greater than (>).

Explanation:
By comparing two numbers 239 and 179:
239 is greater than 179.
Fact: In mathematics, the greater than symbol is a basic mathematical symbol that is used to represent the inequality between two values. The symbol used to represent the greater than inequality is “ > “. This is the universally adopted math symbol of two equal-length strokes joining in the acute angle at the right.
The typical use of the greater than symbol is to compare two values in which the first number is greater than the second number or one value is greater than the other one. The greater than symbol is an approximation of a closing angle bracket. We can see its huge application in descending order, where the arrangement from the largest number to the smallest number is done using greater than a symbol.

Go Math Lesson 2.2 2nd Grade Answers Question 2.

Answer:

Explanation:
By comparing two numbers 435 and 437
435 is less than 437.
Fact: In Mathematics, the less-than symbol is a fundamental Mathematical symbol that describes the inequality between two values. There are different symbols in Maths, which are used to perform different arithmetic operations, hold some constant values, as well as used to compare the quantities with the help of equality and inequality symbols.
The Less-than symbol is to compare two values in which the first number is less than the second number, such as in ascending order. The less than symbol is an approximation of the opening angle bracket. The symbol used to represent the less than inequality is “< “. Less than sign is a universally adopted math symbol of two equal measure strokes that meet in the acute angle at the left.

Question 3.

Answer: greater than

Explanation:
By comparing two numbers 764 and 674
Here we apply rule 2:
Rule 2: Numbers starting with a greater digit
This rule is applicable when two numbers are having the same number of digits. In such cases, we need to check the digit at the leftmost place, whichever is greater. Therefore, the number with a greater digit at the leftmost place of the number is greater than the other number.
Applying by above rule now we compare the numbers:
764 and 674: 764 is greater than 674.
The left side digit is greater than the other side. So it is greater.

Go Math Grade 2 Lesson 2.2 Answer Key Question 4.

Answer: less than

Explanation:
– Since, both the numbers, 519 and 572 have three digits, thus we will compare the left-most digit of both numbers.
5=5, both are equal.
– Now compare the second-most digits 1 and 7
1<7
Therefore, 519 < 572
Hence, 519 is less than 572.

– Now compare the second most digits 3 and 5
3<5
Therefore, 378 < 504
Hence, 378 is less than 504.

Question 6.

Answer: equal to (=)

Explanation:
– 821 and 821 both the numbers have an equal number of digits, therefore, we will compare the left-most digit of both the numbers.
– As we can see the first three digits are the same for both numbers, thus we can say both numbers are equal
Hence, 821 is equal to 821.

Go Math 2nd Grade Lesson 2.2 Answer Key Question 7.

5 > 4
Therefore,
560 > 439
Hence, 560 is greater than 439.

Question 8.

Answer: less than

Explanation:
– 934 and 943 both the numbers have an equal number of digits, therefore, we will compare the left-most digit of both the numbers.
– But the left-most digit is also the same for both numbers, i.e.,9. So, we need to check the second left-most digit.
– 3 < 4
therefore,
934 < 943
Hence, 934 is less than 943.

Answer: Place value.
Place value in Maths describes the position or place of a digit in a number. Each digit has a place in a number. When we represent the number in general form the position of each digit will be expanded. Those positions start from a unit place or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on.
We placed digits in different ways in place values.

We need to fill the three digits: –  –  –
Already given 4 is in the hundreds place:
4 – –
Now we need to fill the two blanks above. Here asked the sum of digits should be 6. This can be explained below:
*Since the first digit is 4, the sum of the last two digits must be 2. So they can either be two 1’s or a 0 and a 2.
In the question given that it has a greater digit in the tens place than in one’s place:
* The above rule out two 1’s. So that means 0 and 2 will occupy the next two places since the tens digit is greater it must be 2 and one’s digit is automatically 0. So the answer is 4 2 0.
Now if we add these three digits 4+2+0, we get 6 only.

Describe how the two numbers are alike. Describe how they are different.
Answer: The only difference is two numbers are place values.
In Mathematics, place value charts help us to make sure that the digits are in the correct places. To identify the positional values of numbers accurately, first, write the digits in the place value chart and then write the numbers in the usual and the standard form.
For example:

Model and Draw

Write how many hundreds, tens, and ones there are in the model. What are two ways to write this number?

Answer:

Place value: Place value in Maths describes the position or place of a digit in a number. Each digit has a place in a number. When we represent the number in general form, the position of each digit will be expanded. Those positions start from a unit place or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on.
There are 2 blocks of hundreds it is equivalent to 200 so it was 2*100=200.
There are 4 blocks of tens it is equivalent to 10 so it was 4*10=40

Lexi needs 144 beads. A large box holds 100 beads. A medium box holds 10 beads. A small box holds 1 bead. Lexi already has 1 large box and 4 small boxes. How many medium boxes of beads does she need?
(A) 104
(B) 4
(C) 40
Answer: Option B is correct.

Explanation:
The total number of needs Lexi needs=144
The number of beads a large box can hold=100
The number of beads a medium box can hold=10
The number of beads a small box can hold=1
The number of large boxes she has already=1
The number of small boxes she has already=4
The number of medium boxes she has=X
We need to find out the number of medium boxes so that he could have 144 beads.
As we know 1 large box=100 beads
1 small box=1 bead, likewise 4 small boxes means Lexi is having 4 beads.
The total number of beads he has now=100+4=104.
Now to calculate the remaining beads we need to subtract the total beads he needs and the beads he has now.
Remaining beads=144-104
Remaining beads=40.
Now we got the remaining beads from this we can calculate the medium boxes.
X=40/10
X=4.
Therefore, she needs 4 medium bags.

Tess has 2 boxes of 10 beads, 4 boxes of 100 beads, and 6 boxes of single beads. How many beads does Tess have in all?
(A) 642
(B) 426
(C) 246
Answer: Option B is correct.

Explanation:
The number of boxes of beads Tess have=2 (medium box)
The number of beads in each box=10
The total number of beads in 2 boxes=2*10=20
The number of boxes of beads Tess have=4
The number of beads in each box=100 (large boxes)
The total number of beads in 4 boxes=4*100=400
The number of boxes of beads Tess have=6 (small boxes)
The number of beads in each box=1
The total number of beads in 6 boxes=6*1=6
Now add all the total beads:
20+400+6
=426.
Therefore, overall 426 beads.

Write the number. Use digits to write how many hundreds, tens, and ones.

FOR THE TEACHER • Read the following: Evan has 426 marbles. How many hundreds, tens, and ones are in 426? Continue the activity for 204 and 341.
Answer:

Explanation:
The given numbers are 426, 204, and 341.
Expanded form:
In Mathematics, the value of each digit in the number can be written in the expanded form. The numbers that are represented as the sum of each digit multiplied by its place value is called the expanded form of the numbers.
An expanded form of 426: 400+20+6
Each number has a place value. It determines the value of that digit according to its position in the number. The value of a digit in a number increases as we move from left to right. The digits on the left have lower place values than the digits on the right.
using place value to express the number:

Likewise, we need to write for 204, and 341
The expanded form of 204: 200+0+4
The expanded form of 341: 300+40+1.

How many hundreds are in 368? Explain.
Answer: 3 hundreds.
Explanation:

Each digit in a number has a specific value depending on where in the number it is located.
The value of each digit in a number is determined by its location in the numeral. The use of a place value chart aids in the recognition of big numbers. From left to right, we read the numbers using a place value chart. In the Indian system, we begin arranging numbers from right to left in groups of three and then in two groups. The place value chart is divided into periods, including ones, thousands, lakhs, and crores.
Hundreds = 10² = 100
Tens = 10¹ = 10
Ones = 10^{0 = 1}
This can be written in expanded form also: 300+80+6
3 is in the hundreds place
8 is in the tens place
6 is in the ones place.

The expanded form of a number 536: 500+30+6
3. word form: This is a way to write a number in words only, also need to include commas separating the periods. If there are commas in standard form, there must be commas in word form.
The word form of 536: five hundred thirty-six
4. Place value chart: Place value in Maths describes the position or place of a digit in a number. Each digit has a place in a number. When we represent the number in general form, the position of each digit will be expanded. Those positions start from a unit place or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on.
The place value chart of 536:

5 is in the hundreds place
3 is in the tens place
6 is in the one’s place.
In Mathematics, place value charts help us to make sure that the digits are in the correct places. To identify the positional values of numbers accurately, first, write the digits in the place value chart and then write the numbers in the usual and the standard form.

H.O.T. Multi-Step Ellen used these blocks to show 452. What is wrong? Cross out blocks and draw quick pictures for missing blocks.

Answer:

Explanation:
The above-given diagram in the question was wrong.
The given number 452
– This 452 can be written as 4 hundreds 5 tens 2 ones.
– but in the diagram 3 blocks of a hundred is given which is equivalent to each block having 100 marbles.
– We need to draw 4 blocks of hundreds, 5 blocks of tens, and 2 blocks of one’s.
– Or else we can write in expanded form: 400+50+2
– 4 is in the hundreds place
– 5 is in the tens place.
– 2 is in the one’s place.

Question 7.
H.O.T. Think of a 3-digit number with a zero in the ones place. Use words to write that number.
Answer: 100, 110, 120, 130, 140, 150, and so on…
Explanation:
The numbers are broadly classified based on the number of digits. Here, we shall look at the 3-digit numbers, their formation, and the importance of numbers and place values. The digits used to form higher digit numbers are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The place value of a 3-digit number helps in understanding the value of each of the digits. The smallest of 3-digit numbers is 100 and the largest number is 999.
Let us look at some of the below mentioned important points relating to 3-digit numbers. These help in a better understanding of 3-digit numbers.
1. 100 is the smallest 3-digit number and 999 is the greatest 3-digit number.
2. A 3-digit number cannot start with 0.
3. 10 tens make 1 hundred which is the smallest 3-digit number and 10 hundred make a thousand which is the smallest 4-digit number.
4. A 3-digit number can also have two zero’s. The two zero’s should be in the ten’s place and the unit’s place. Some of the examples of 3 digit numbers are 100, 200, 300, 400. The only necessary condition is that the zeroes cannot be in the hundredth place.
5. A 3-digit number can also have one zero. The one zero should be in the unit’s place. Some of the examples of 3 digit numbers are 100, 110, 120, 130, and so on… The only necessary condition is that the zeroes cannot be in the hundredth place.

FOR THE TEACHER • Read the following to children. Jack wants to draw a point on his number line for a number greater than 70. Audrey wants to draw a point on her number line to show where 22 belongs. Draw to show points that Jack and Audrey could draw.
Answer:
Number line: A number line is a pictorial representation of numbers on a straight line. It’s a reference for comparing and ordering numbers. It can be used to represent any real number that includes every whole number and natural number. Just to recollect, the whole number is a set of numbers that include all counting numbers (1, 2, 3,4,5,6 …….) and zero (0), whereas the natural number is the set of all counting numbers i.e. 1, 2, 3, 4, 5, 6……..
Jack’s Number line:
Jack’s should draw the number line greater than 70. This number line will represent as:

Audrey should point out the 22 on the number line:

Math Talk

Explain how you decided where Jack and Audrey could draw their points.
Answer: Arithmetic operations of numbers can be better explained on a number line. To begin with, one must know to locate numbers on a number line. According to the question we need to point the numbers. number lines are the horizontal straight lines in which the integers are placed in equal intervals. All the numbers in a sequence can be represented in a number line. This line extends indefinitely at both ends.
Here Jack should point the numbers more than 70. So we should place the numbers on the number line. For example, I had placed numbers from 60 to 80 then easily we can point out the numbers that are greater than 70.
Now coming to Audrey, he should point to the number 22. So the number line starts from 20 and the sequence will go on.

Question 1.
Write the number that belongs at each point.

Answer: Representation will be shown below:

Definition of number line: A visual representation of numbers on a straight line drawn either horizontally or vertically is known as a number line. Writing down numbers on a number line makes it easy for us to compare them and to perform basic arithmetic operations on them. There are three parts of a number line which are – negative side, zero, and positive side. Numbers to the left of 0 are negative numbers and numbers to the right of 0 are all positive numbers. So, we can say that on a number line, the numbers present on the right are larger than the numbers on their left.
How to draw a number line:
Step 1: Draw a horizontal line with arrows on both ends. [You can also draw a vertical number line].
Step 2: Choose a scale depending on the given number. In the above problem, the sequence is counting by 1’s.  [Determining an appropriate scale depends on the factors of the given number]
Step 3: Mark the points at equal intervals. So, if you have chosen 1 as the scale, then mark 62, 63, 64, 65 and so on.
Step 4: Locate the given number. Highlight that point with a circle.
