Putting Parts Together – Addition Equations and Problems

Key Concepts

• Adding parts together.
• Addition equation.

Introduction 

1 red balloon and 9 blue balloons. How many in all?

The parts are 1 and 9 

The parts are 1 and 9

Now we will add the parts to give the whole, again the whole is an addition

The addition equation is 1 + 9 = 10 

So, there are 10 balloons in all.  

Examples 

Example 1: 

2 green ice creams and 6 yellow ice creams. How many in all? 

The parts are 2 and 6

The parts are 2 and 6 

Now we will add the parts to get the whole, again the whole is an addition  

The addition equation is 2 + 6 = 8 

So, there are 8 ice creams in all.  

Higher – Order Thinking 

2 apples, 6 oranges, 2 kiwis, and 5 bananas. How many fruits in all? 

Draw the picture and write the addition equation.  

Solution: 

2 + 6 + 2 + 5 = 15
