### Teaching and Group Activities for Understanding

**Day 1 Teaching**

Show children a 0-20p money line; mark 8p and say you want to add another 5 pennies. Write 8p + 5p = __ p. Let’s add by bridging 10p. How many will get me from 8p to 10p? [2] Draw a hop of 2p to 10p. How many more to add? Show the 3 pennies. Where will that get me to on the money line? Draw a hop of 3p to 13p. So how much money do I have altogether? Record: 8p + 5p = 13p. Repeat for 7p + 6p.**Group Activities**

-- Use penny lines to help solve money additions.

-- Use penny lines to help solve money additions, adding 1-6p or 1-10p.

**Day 2 Teaching**

Show 14p in a piggy bank; tell children that Holly is not allowed to buy anything that will bring her money below 10p. Discuss and sort price labels of things she can buy and those she cannot. Share calculating some subtractions that do bridge 10p. Record number sentences.**Group Activities**

-- Subtract amounts of money, continuing to practise recognising calculations that will bridge 10.

**Day 3 Teaching**

Show children a money word problem. Read it together and discuss how we can act it out. Choose 2 children to role play the problem. Record what we have to do as a number sentence: 15p + 5p + 2p = ? Help children use number bonds to find the answer. Repeat for problem 2.

**Group Activities**

Use the in-depth problem-solving investigation ‘Butterfly flowers’ from NRICH as today’s group activity.

Or, use this activity:

-- Solve addition and subtraction word problems. Use role-play to help visualise the problem.
