### Teaching and Group Activities for Understanding

**Day 1 Teaching**

Use the ITP Number grid to demonstrate counting in 5s. Look at the patterns, and identify large multiples of 5. Then count in 5s from numbers other than 0 or 5. Identify patterns.

**Group Activities**

Use the ‘Multiple Madness’ in-depth problem-solving investigation below as today’s group activity.

Or, use these activities:

-- Complete and describe number patterns that involve 2s, 5s and 10s.

-- Investigate statements about patterns; decide if they are always true, sometimes true or never true.

**Day 2 Teaching**

Show children seven 5p coins. Count in 5s to establish how much. Create an array of 7 x 5 and state that 5 + 5 + 5 + 5 + 5 + 5 + 5 is seven lots of 5 or seven fives, which we can write as 7 x 5, read as seven times five. Repeat with other arrays for different multiples of 5.

**Group Activities**

-- Rolling a 1-10 dice then multiply the number by 5.

-- Multiply strips of 5 stickers up to 10 and record the calculation.
