### Teaching and Group Activities for Understanding

**Day 1 Teaching**

Make labels 11p, 12p, 15p and 20p and attach to food items. Give each pair of children a pot of 1p, 2p, 5p, 10 and 20p coins, several of the smaller denominations. Show different items; children show you coins to pay for each 1. Discuss.

**Group Activities**

Use the ‘Mr Know It All’ in-depth problem solving investigation below as today’s group activity.

Or, use these activities:

-- Guess the coins in each pocket, using the clues.

-- Buy food, working out which coins they would use to pay for it.

**Day 2 Teaching**

Have a selection of toys with prices 1p to 11p. Choose 2 items. Show children an enlarged 0-20p money line and use this to model counting on. Children start with the larger and count on the smaller price.

**Group Activities**

-- Buy two or three items, using number facts or counting on to find totals.

**Day 3 Teaching**

Show children items with price labels 67p, 42p, and 56p. Say that all these prices are going to go up by 10p! What's a quick way to add 10p? Spider counting. Show a 1-100 grid. Model counting on 10p to find new prices.

**Group Activities**

-- Find prices for the car wash, adding 10p, 20p or 30p to amounts.
