lesson 5 algebra 1 use letter and symbols to represent unknowns

Entry Activity Recognise multiples and use simple tests of divisibility

What’s a multiple?Write down the 1st five multiples of 6...

6, 12, 18, 24, 30

How can we check if something is a multiple?Is 32 a multiple of 8?32 ÷ 8 = 4 so yes it is!

Match the multiple to the sequence
