Solve addition problems to 100 by counting on in their heads.
Number Framework Stage 4
Using Materials
Problem: “A class is growing beans from bean seeds. When they leave school on
Monday, six seeds have sprouted. When they come to school on Tuesday morning, they find that eight seeds have sprouted altogether. How many seeds have sprouted
overnight?”
Discuss why the problem amounts to solving 6 + □ = 8. The students solve the
problem with counters and discuss their methods. Encourage the students to count on
by pointing at their fingers and saying “seven, eight, so the answer is two”.
Record 6 + 2 = 8 on the board or modelling book.
Examples: Word stories and recording for: 4 + □ = 6 5 + □ = 6 7 + □ = 8
7 + □ = 9 6 + □ = 8 6 + □ = 9
Using Imaging
Shielding and Imaging Only: Examples: Word stories and recording for: 12 + □ = 14
8 + □ = 10 12 + □ = 15 7 + □ = 11 8 + □ = 11 9 + □ = 12 ...
Using Number Properties
Examples: Word stories and recording for: 87 + □ = 89 43 + □ = 45
79 + □ = 83 51 + □ = 54 □ + 56 = 59 □ + 43 = 45 58 + □ = 63 ...
