Year 3 addition and subtraction with a Stone Age twist!
We used conkers, leaves and twigs to help us with our calculations.
We drew large place value charts and represented hundreds as leaves, tens as twigs and ones as conkers. Our aim by the end of the lesson was to understand how to exchange 10 ones for 1 ten and 10 tens for one hundred to help us add and subtract tens to 3 digit numbers. We were so excited and it really helped us understand our calculations more. We will continue to use this idea especially when we move onto column addition and subtraction.
