Use the counting chart. Count backward by ones. Write the numbers. TEKS 1.5.A

Question 1.
52, 53, ___, ___, ___, ____
Answer: 52, 53, 54, 55, 56, 57.
It is a forward counting. Let’s take a look at the counting tracks. Notice the first row having 1 to 10. The second row has 11 to 20. Each number begin with 1, the second digit increases by 1 until the last column. In the third row, the pattern is the same only difference is the first digit is 2 instead of 1 and the second digit is increased by 1 until the last column. Notice that the second digit in each column is the same. Let’s skip down to 100 and the pattern continues. Now we have three-digit numbers like 101, 102, 103, 104, 105 and so on… and every third digit is increased by 1.

Question 2.
115, 116, ____, ___, __, _____

Explore

Start on 10. Count forward by tens. Color each number as you say it.

Answer:
In math, to count can be defined as the act of determining the quantity or the total number of objects in a set or a group.

Explanation:
The number we need to start from 10. From there we need to add 10s. By using the skip count by 10 technique we should add 10.
By math sentence,
10+10=20
20+10=30
30+10=40
40+10=50
50+10=60
60+10=70
70+10=80
80+10=90
90+10=100 and so on… so I coloured the last column in the counting track.

FOR THE TEACHER • Read the following problem. When counting by tens, what number comes after 40?
Answer:
50 will come after 40 when we continue adding 10. I represented n the below diagram.

Mathematical Processes

Which numbers the hundred chart, did you colour? Explain.
Answer:
A hundred board is one of the best math resources you can have available for your child. It can help with counting, number recognition, adding and subtracting, and even discovering number patterns.
Here, I coloured the last column in the counting chart because the question asked to start from 10 and count the numbers by using skip count by 10.
The numbers I coloured was 10, 20, 30, 40, 50, 60, 70, 80, 90, 100.
Adding 10 to every number we get the next number.

Question 14.
Multi-Step Kay’s fish tank only holds 120 fish. She adds 10 fish once a week. She does this for 2 weeks. How many more weeks will it take to fill the tank?
(A) 12
(B) 10
(C) 8
Answer: Option B is correct.

Explanation:
The total number of fishes in the tank=120
The number of fishes she adds in a tank once a week=10
The number of weeks she added 10 fishes in the tank=2
Already she added 20 fish. An extra 100 fishes need to add to the tank.
We need to calculate the number of weeks she used to take to add all the fish in the tank.
The number of weeks=X
X=100/10
X=10.
It means she takes 10 more weeks to add the fish.

Mathematical Processes

Explain When would it be useful to count tens?
Answer:
Skip counting is often called counting by 2s or by 5s or by 10s or by 100s. Skip counting really helps with addition, subtraction, multiplication, and division. It is also used a lot for counting things – counting pairs of gloves, groups of five, money, boxes with 100 cans in each box – the list goes on!
How to skip count: To skip count you add the same number over and over. You can start at any number. When you count normally (like 1,2,3,4,5,6) you add 1 to get the next number. To count by 10s, you add 10 to get the next number.
Counting by tens: The two examples below show counting by tens. Look at the numbers. There is always a pattern.
