### Teaching and Group Activities for Understanding

**Day 1 Teaching**

Use 5 jumps of 7 and 7 jumps of 5 along a 0-50 beaded line to show that these come to the same place. Then show an array of 5 rows of 7 cubes and turn it round to be 7 rows of 5 cubes. Stress commutativity.**Group Activities**

-- Exploring arrays and writing corresponding number sentences.

**Day 2 Teaching**

Revise 2x table and focus on division, stressing that 12 x 2 = ? is one way of learning the fact and another is ? x 2 = 24: how many 2s in 24? Use ITP Number Grid; highlight multiples of 2, asking division questions.**Group Activities**Use the 'Make the Multiples' in-depth problem-solving investigation below as today’s group activity.

Or, use these activities:

-- Finding out how many 2s are in a number using jumps and beaded lines as well as calculating.

**Day 3 Teaching**

Write 35, 24, 42, 95, 46, 50, 102, 105, 120 and 125 on the IWB on separate cards. Draw 3 intersecting sets labelled ‘multiples of 2’, ‘multiples of 5’ and ‘multiples of 10’. Discuss how to allocate each number.**Group Activities**

-- Playing games exploring multiples of 2, 5, and 10 (as appropriate).
