Complete the sentences. 2 in each row. There are _____ 3 rows. There are _____ 2 + _____2+ _____ =2_____ 6 altogether. There are _____ 6

Fluency Complete the sentences. 5 in each row. There are _____ 2 rows. There are _____ 5 + _____5= _____ 10 altogether. There are _____

Complete the sentences. 2 in each row. There are _____ 2 rows. There are _____ 2 + _____2= _____ 4 4 altogether. There are _____

Fluency Complete the sentences. 10 in each row. There are _____ 3 rows. There are _____ 10 + _____10+ _____ 10 _____ = _____ 30 30 altogether. There are _____

The matching number sentence is 5 + 5. Dom The matching number sentence is 3 + 3. Kat Who do you agree with? Explain your answer. Dom is correct. There are 5 in each row and there are 3 rows.

What array could be built with 6 cubes? Build, draw and describe the array. or 2 on each row. 3 rows. 3 on each row. 2 rows.

Lesson 2 Step: Make arrays

Fluency 2+2+2+2

Fluency Complete the sentences. 2 in each row. There are _____ 4 rows. There are _____ 2 + _____2+ _____ +2_____ = _____ 2 _____ 8 altogether. There are _____ 8

Complete the sentences. 5 in each row. There are _____ 3 rows. There are _____ 5 + _____5+ _____ =5_____ 15 15 altogether. There are _____

Complete the sentences. 10 in each row. There are _____ 4 rows. There are _____ 10 + _____10+ _____ +10_____ = 10 _____ 40 altogether. There are _____ 40

Reasoning What mistake has been made in the array above? There an unequal amount of squares in the array. One of the row contains 4 instead of 5.

Build and draw an array to match the description. There are 5 rows. There are 2 on each row. Problem solving

Lesson 3 Step: Make arrays

What is the difference between a row and column? Rows go across Columns go down 2 rows. There are _______ 5 columns. There are _______5 in each row. _______ 2 in each column. Fluency

Fluency Complete the sentences. 4 rows. _______ 2 in each row. _______ 2 columns. _______ 4 in each column. _______

Fluency Complete the sentences. 3 rows. _______ 10 in each row. _______ 10 columns. _______ 3 in each column. _______

Fluency Complete the sentences. 4 rows. _______ 5 in each row. _______ 5 columns. _______ 4 in each column. _______

Fluency Complete the table. Array Describe: Rows Describe: Columns Number sentence 3 rows. _____ 2 columns. 2+2+2 2 in each row. _____ 3 in each column. _____ 3+ 3 2 rows. _____ 5 columns. 5+5 5 in each row. _____ 2 in each column. _____ 2+2+2

Fluency Complete the table. Array Describe: Rows Describe: Columns Number sentence 2 rows. _____ 2 columns. 2+2 2 in each row. _____ 2 in each column. _____ 3 rows. _____ 5 columns. 5+5+5 5 in each row. _____ 3 in each column. _____ 3+3+3

My array has 3 rows and 2 columns. The total number of counters must be an odd number. True or false? False. An array with 2 rows and 3 columns will use 6 counters. 6 is an even number.

The number sentence that represents the array is: 10 + 10 Complete the array to show this. Problem solving

Lesson 4 Step: Make doubles (Practical)

Fluency Has this representation been doubled? No

Has this representation been doubled? Yes

Fluency Has this representation been doubled? No

Has this representation been doubled? No

2 Double 1 is _______

4 Double 2 is _______

Double _____7 is _____14

Double _____5 is _____10

Dom says, If I double 4, the answer will be equal to 12 – 6. Do you agree with Dom? No, double 4 is 8. 12 – 6 = 6.

Double 8? is 16

Lesson 5 Step: Make doubles

Double _____3 is _____ 6

Double _____4 is _____ 8

Double _____7 is _____14

10 is _____20 Double _____

Fluency Complete the table. Build Represent Add Double 1+1=2 2 Double 1 = ______ 2+2=4 4 Double 2 = ______

Fluency Complete the table. Build Represent Add Double 3+3=6 6 Double 3 = ______ 4+4=8 8 Double 4 = ______

Reasoning Spot and explain the mistake. Build Represent Add Double 5 + 5 = 10 Double 5 = 10 There are 12 cubes in total (6 have been doubled). There should be 10 cubes in total (5 doubled).

Double the amount shown will give an even number. True or false? True. Double 6 = 12.
