IndianTechnoEra: Addition Facts

Addition Facts

Addition facts are simple addition combinations that we learn and understand so that we can solve basic addition problems more easily.

We can learn these facts by using objects, pictures, counting and number patterns.

Learning Objectives

• Understand simple addition facts.
• Use counting to find addition answers.
• Recognise common number combinations.
• Complete missing numbers in simple addition facts.

What Is an Addition Fact?

An addition fact is a simple addition sentence whose numbers and answer are known.

2 + 3 = 5

This tells us that putting 2 and 3 together gives 5.

Using Counting to Find an Answer

We can use counting to solve addition facts.

3 + 2 = ?

Start at 3 and count two more:

4, 5

3 + 2 = 5

Common Addition Facts

1 + 1 = 2

2 + 1 = 3

2 + 2 = 4

3 + 2 = 5

4 + 2 = 6

5 + 3 = 8

Making Ten

Some addition combinations make 10.

5 + 5 = 10

6 + 4 = 10

7 + 3 = 10

Recognising combinations that make 10 will be useful when you learn more addition strategies later.

Finding a Missing Number

Sometimes part of an addition fact is missing. We can find the missing number by thinking about the total.

3 + ___ = 5

We need 2 more to make 5.

3 + 2 = 5

Practice Addition Facts

1. 1 + 2 = ___

2. 2 + 3 = ___

3. 4 + 1 = ___

4. 5 + 2 = ___

5. 6 + 4 = ___

Common Mistakes

• Guessing an answer without counting or thinking.
• Changing one of the numbers while counting.
• Forgetting the total.
• Trying to memorise facts without understanding them.

Try It Yourself

Choose five simple addition facts. Solve each one by counting or using objects first. Then try to remember the answers.

Understand → Count → Solve → Remember

Quick Revision
