Answer:

Explanation:
Counting numbers are the set of numbers that we use to learn how to count. 1, 2, 3, 4, 5, and so on. They are also called natural numbers—maybe since they feel natural to us because they are naturally the first numbers we learn. Sometimes they are also referred to as positive integers.
count-on: Mental math strategy to add two numbers. We start with the biggest number of the numbers to add and count up to the second.
Counting back: A method of learning subtraction by counting backwards from the first number in the problem to get the answer.

Understand Vocabulary

Question 1.
Circle the addition sentence.
3 + 6 = 9
9 – 6 = 3
Answer:

Explanation:
In the question asked circle the addition sentence.
– 3+6=9 is an example of an addition number sentence.
– The ‘+’ sign is called a plus sign or an addition sign.
– We combine the numbers of either side of the plus sign together to make a total.
– In the example of 3+6, the plus sign means to combine the 3 and 6 together.
– In total, 3 counters plus 6 more counters to make 9 counters.
– The ‘=’ sign is called the equals sign.
– In the number sentence the equal sign means that the total value on the left of the equals sign is the same as the total value on the right of the equals sign.
– This addition number sentence read as the ‘three add six equals nine’.

Question 2.
Circle the subtraction sentence.
8 + 2 = 10
10 – 2 = 8
Answer:

Explanation:
The symbol “-” signifies subtraction. A subtraction process consists of three parts of numbers, namely minuend, subtrahend and difference. The number in a subtraction sentence from which we subtract another number is called a minuend, which means the minuend is the first number in a subtraction process.
Given 10 – 2 = 8
Here,
10 = Minuend
2 = Subtrahend
8 = Difference
And, “-” is the minus, i.e. the symbol for subtraction and “=” is the equal sign.

Question 3.
Circle the count on fact.
5 – 1 = 4
4 + 1 = 5
Answer:

Explanation:
Mental math strategy to add two numbers. We start with the biggest number of the numbers to add and count up to the second.
Count-on facts are numbers 0 – 9 that only add +1, +2, +3. When practising count-on start with the largest number and count up. For example 5+3. Say 5 and then count-on 6,7,8

Unit 1 Whole Numbers and Operations Answer Key Question 4.
Circle the count back fact.
8 – 2 = 6
6 + 2 = 8
Answer:

A method of learning subtraction by counting backwards from the first number in the problem to get the answer.
We need to count backwards from 8:
8, 7, 6. This is how we count backwards.
