Monday Add by counting on
First Then 8 First there were _____. 7 more were added. Then _____ 15 Now there is _____. Now Fluency
First Then 9 First there were _____. 4 more were added. Then _____ 13 Now there is _____. Now Fluency
First Then 5 First there were _____. Then 12 _____ more were added. 17 Now there is _____. Now Fluency
Fluency Start at 6 Count on 4 0 1 2 3 4 5 6 6 + 4 = 10 7 8 9 10
Fluency Start at 14. Count on 20. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 14 + ______6=___ 20 ______
Reasoning Spot and explain the mistake. 6 + 8 = 14 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 The jumps on the number line show 8 + 6. It should show 6 plus 8 more.
Wednesday Step: Adding by making 10
Recap: Complete the table to show number bonds to 10. Part 1 1 8 5 7 7 1 4 8 4 10 Part 2 9 2 5 3 3 9 6 2 6 0 Fluency
Fluency 14 5 + 9 = _______ 5 + 5 9 = 4 14 so 10 + 4 = 14
Fluency 13 7 + 6 = _______ 7 + 3 6 = 3 13 so 10 + 3 = 13
Fluency 12 4 + 8 = _______ 4 + 6 8 = 2 12 so 10 + 2 = 12
Fluency 17 9 + 8 = _______ 9 + 1 8 = 7 17 so 10 + 7 = 17
Fluency 11 7 + 4 = _______ 7 + 10 + 1 3 = 10 = 11
Fluency 15 8 + 7 = _______ 8 + 10 + 5 2 = 10 = 15
Fluency 13 9 + 4 = _______ 9 + 10 + 3 1 = 10 = 14
Thursday Number bonds to 20
Fluency 8 black counters. There are _____ 12 red counters. There are _____ Altogethere are _____20 counters. 8 + _____12= _____ 20 _____ 8 _____ +12 _____ = _____ 20
Fluency 4 black counters. There are _____ 16 red counters. There are _____ Altogethere are _____20 counters. 4 + _____16= _____ 20 _____ 4 _____ +16 _____ = _____ 20
Fluency 11 black counters. There are _____ 9 red counters. There are _____ Altogethere are _____20 counters. _____ 11 + _____9= _____ 20 _____ + 9_____ = _____ 11 20
Fluency Complete the part-whole models to show bonds to 20. 20 5 20 15 ? 8? 12
Fluency Complete the part-whole models to show bonds to 20. 20 1 20 ? 19 7? 13
Fluency Complete the part-whole models to show bonds to 20. 20 9 20 11 ? 6? 14
Problem solving How many different ways can you complete the part-whole model below to show bonds to 20? There are 21 different part-whole models that can be made: 20 ? ? 0, 1, 2, 3, 4, 5, 20 19 18 17 16 15 6, 14 7, 13 8, 12 9, 11 10, 10 11, 9 12, 13, 14, 15, 16, 17, 8 7 6 5 4 3 18, 2 19, 1 20, 0
Friday Compare number bonds
< = > less than equal to greater than 3 < 10 10 = 10 10 > 1
Fluency Match the number bonds. + + + +
Fluency Tick the number sentence that show equal bonds. 6+2 5+2 2+7 1+6 1+8 7+3 3+4 4+5
Fluency Use <, > or = to make the comparisons correct. 2+7 < 7+3 5+4 > 2+6 8+1 = 9+0 5+2 = 4+3
Fluency Use <, > or = to make the comparisons correct. 9+1 > 3+6 7+2 = 4+5 6+2 < 4+5 1+6 = 7+0
Reasoning 5+ ? > 2+6 The number 3 could go in the box. Mo The number 4 could go in the box. Jess Who do you agree with? Explain why. Jess as 5 + 4 = 9 and this is greater than 2 + 6 which equals 8.
