➕ Adding within 10
Class 1 Maths · Unit 4 of 12 · about 120 minutes
This unit introduces addition as putting together and counting on, using the + and = signs. Children build sums up to 10 with objects, pictures and number stories, and learn that adding zero leaves a number unchanged. It builds directly on counting to 9 and prepares for subtraction within 10 and later work within 20.
What your child will learn
- Students will be able to combine two groups of objects and count the total to find the sum up to 10.
- Students will be able to use the + and = signs to write an addition equation for a picture or story.
- Students will be able to count on from the larger number to add two numbers within 10.
- Students will be able to solve simple addition story problems within 10 and explain their answer.
- Students will be able to add zero to any number within 10 and state that the number stays the same.
Lessons in this unit
- Putting together: Combine two groups of objects and count all to find the total. Use concrete objects and pictures. Introduce the word 'add'.
- The + and = signs: Introduce the + and = symbols. Read and write simple addition equations like 3 + 2 = 5. Connect symbols to the action of putting together.
- Counting on: Learn to count on from the larger number to add faster. For 2 + 6, start at 6 and count 7, 8. Use number line and fingers.
- Number stories: Solve simple addition word problems within 10. Identify the two groups and the total. Use pictures and objects to help.
- Adding zero: Understand that adding zero means adding nothing, so the number stays the same. Practice with objects and equations.
Key words
- add
- Put groups together to find how many in all.
- plus
- The + sign means 'put together'.
- equals
- The = sign means 'is the same as'.
- sum
- The answer when you add.
- count on
- Start from a number and count forward.
- zero
- Nothing. Adding zero means nothing is added.

What to watch for
- Counting the same object twice when groups overlap.
- Help: Move objects one by one into a new pile and count each once.
- The = sign means 'the answer comes next'.
- Help: Show that both sides are the same: 3 + 2 is the same as 5.
- Always start from the first number in the equation.
- Help: You can start from the bigger number to count fewer steps.
- The word 'more' always means subtract.
- Help: In stories, 'more' often means adding. Read carefully.
Try this at home
- Count 3 apples, then 2 mangoes; push them into one pile and count all: 1, 2, 3, 4, 5
- Picture of 2 apples and 3 mangoes: say "2 plus 3 equals 5" and write 2 + 3 = 5
- 2 + 6: start at 6, count 7, 8 → 8
- Riya has 3 toffees. She gets 2 more. Count 3, then count on 4, 5 → 3 + 2 = 5 in all
Quick questions to ask aloud
- Riya has 2 apples and 3 mangoes. How many fruits in all?
Show answer
Put the 2 apples and 3 mangoes together. Count: 1, 2, 3, 4, 5. So 5 fruits. - What does the + sign mean? (Put together / Take away / Nothing)
Show answer
Put together. The + sign means 'add' or 'put together'. - What is 2 + 6? Count on from 6.
Show answer
Start at 6. Count 2 more: 7, 8. So 2 + 6 = 8.
