Great news: we have just added 15 more on-screen activities to challenge children on mental division. They concentrate on mental division by 11 and 12, including bar models to help visualise the problems, as well as finding numbers that are divisible by 11 and 12.These can be quite tricky, especially if children have not yet gained an excellent knowledge of multiplication tables, but with unlimited practice these games are a great way to become fast and accurate with mental calculations.Go to Year 4 Division on-screen activities
