Number Bonds Sum 8
Overview
When you add groups of objects together, you can find how many there are in all.
You can add large or small numbers together. You can add two or more groups together.
It is helpful to know the addends that can make up each sum.
For example, 2 + 0 = 2 and 1 + 1 = 2. These are the number bonds for 2.
Let’s focus on number bonds for 8.
Look at the picture above: 8 is 5 + ?
The word is can be replaced with the = to make the math sentence 8 = 5 + __
We know that
5 + 3 = 8.
Therefore, the missing addend is 3.
8 is 5 plus 3.
Let’s try a few more problems together! Use the pictures to help you solve.
Look at the picture above: 8 is 4 + ?
The word is can be replaced with the = to make the math sentence 8 = 4 + __
We know that
4 + 4 = 8.
Therefore, the missing addend is 4.
8 is 4 plus 4.
Here is another one to try.
Look at the picture above: 8 is 6 + ?
The word is can be replaced with the = to make the math sentence 8 = 6 + __
We know that
6 + 2 = 8.
Therefore, the missing addend is 2.
8 is 6 plus 2.
Let’s try another one!
Look at the picture above: 8 is 7 + ?
The word is can be replaced with the = to make the math sentence 8 = 7 + __
We know that
7 + 1 = 8.
Therefore, the missing addend is 1.
8 is 7 plus 1.
