Revision of Whole Numbers
Pupils should read and write numbers within 1–100.
Example:
21, 22, 23, 24, 25
Revision of Addition
4 + 3 = 7
🍎 🍎 🍎 🍎 + 🍎 🍎 🍎 = 7 apples
Revision of Subtraction
8 − 3 = 5

Take away ⭐⭐⭐
Stars left = 5
Revision of Missing Numbers
5 + \_\_ = 9
Answer: 4
10 − \_\_ = 6
Answer: 4
Revision of Open Sentences
□ + 2 = 7
Answer: 5
9 − □ = 5
Answer: 4
Revision of Number Lines
For addition, move forward.
3 + 3 = 6
For subtraction, move backward.
7 − 2 = 5
Simple Word Problem
Bola has 6 pencils. Her mother gives her 3 more.
6 + 3 = 9
Bola has 9 pencils.
