Aim • I can recall and use multiplication and division facts for the 10 times table. Success Criteria • I can count in 10 s stopping at a given point. • I can keep track of my count on my fingers. • I can recall multiplication and division facts for the 10 times table.

Multiplying by Ten 8 80 6 2 10 60 20 4 40 11 110 9 90 5 50 371 × 10 = 70 30 12 120 10 100

Multiplying by Ten What do you notice? 1 × 10 = 10 7 × 10 = 70 2 × 10 = 20 8 × 10 = 80 3 × 10 = 30 9 × 10 = 90 4 × 10 = 40 10 × 10 = 100 5 × 10 = 50 11 × 10 = 110 6 × 10 = 60 12 × 10 = 120 Can you predict what 14 times 10 would be? What about 20 times 10?

Multiplying by Ten What can you see? Say the number sentence as the answer. 3 × 10 = 30

Multiplying by Ten What can you see? Say the number sentence as the answer. 5 × 10 = 50

Multiplying by Ten What can you see? Say the number sentence as the answer. 8 × 10 = 80

Multiplying by Ten What can you see? Say the number sentence as the answer. 2 × 10 = 20

Multiplying by Ten What can you see? Say the number sentence as the answer. 9 × 10 = 90

Multiplying by Ten Can you make a rule about multiplying by 10? How does the number change? What stays the same? How do you recognise a multiple of 10?

Say What You See Make up as many sentences as you can about this array. 4 times 10 = 40 and 40 divided by 10 = 4 4 × 10 = 40 4 groups of 10 make 40. 40 divided into groups of 10 makes 4 groups. Did you think of any more?

40 ÷ 10 = ? Which array matches the number sentence? 40 ÷ 10 = 4 4 × 10 = 40 Can you think of any more number sentences for this array?

Arrays Activity 3 × 10 = 30 30 ÷ 10 = 3

Instant Recall How quickly can you recall the facts for multiplying and dividing by 10? Let’s find out!

All the 10 s! Count until you reach the number I am holding up. The person who says this number has to say a multiplication or division sentence. Start again from the next person in the circle.
