Thursday's maths
Date: 13th May 2020 @ 11:18pm
Hello everybody,
It has been lovely to see photographs of the children's learning and we are very grateful for all the parents who have taken the time to send photographs in to celebrate their child's work.It is really important that you continue to learn at home so that learning is easier when you come back to school. Try your very hardest to focus and concentrate and remember it is ok if you find learning hard some days as long as you 'have a go' and try your best.
We hope you are all ok and are ready for more learning today. Today we are going to focus on using the bar model strategy to solve subtracttion problems.
