Today (11/10/21) we started working on vertical subtraction sums. To start off we used the Base 10 equipment tp help us understand what the exchanges actually are. we will lbe doing lots of work on subtraction this week. Our homework will also be based on this next week - watch out for a seesaw video from Mr Ritchie showing mums and dads how we do these calculations as it might be a little different from how they were taught (Mr Ritchie was taught a different way himself!).
