### Teaching and Group Activities for Understanding

**Day 1 Teaching**

Display a 0–50 beaded line (see resources) on the Interactive Whiteboard. Write 4 × 5 = on the board. This is 4 lots of 5, or 4 times 5. Children ring groups of 5 beads until they have 4 groups. Say that this is 4 lots of 5 beads. Count in 5s to show that 4 × 5 = 20. Repeat with 3 × 5, 6 × 5, 10 × 5.

**Group Activities**

-- Generate and solve times 5 multiplication sentences with dice, using hops on beaded lines or fingers.

-- Solve and create word problems for multiplication by 5.

**Day 2 Teaching**

Display a 0–30 beaded line on the Interactive Whiteboard (see resources). Write 4 × 2 = on the board. We can read this as 4 lots of 2, or 4 times 2. Ask children to ring groups of 2 beads, until they have ringed 4 groups (4 lots of 2 beads). Count in 2s to show that 4 × 2 = 8. Repeat with 8 × 2, 3 × 10, 5 × 5.

**Group Activities**

Use the in-depth problem-solving investigation ‘Odd Times Even’ from NRICH as today’s group activity.

Or, use these activities:

-- Generate and solve times 2, times 5 and times 10 multiplication sentences, using hops on beaded lines or fingers.

-- Solve and create word problems for multiplication by 2, 5 and 10.
