Name:                              
Date:              

Today I am practising: finding the unknown removed quantity

1

There were 15 beads. Now there are 9. How many beads were removed?

2

Complete 18 − ___ = 11. Draw the start and cross out the removed part.

3

A child has 13 cards and gives some away. Eight remain. Write an equation and find the change.

4

Two jars both start with 16 buttons. One ends with 10, the other with 12. Which lost more buttons?

5

Check 12 − ___ = 7 using an addition equation.

6

Write a story for 20 − ___ = 14 and label the start, change, and result.

Grown-up guide
  1. Encourage a drawing that keeps the starting whole visible.
  2. Ask what the blank represents in the story.
  3. Accept counting up from the remainder or subtracting the remainder from the start.
