This resource will help children understand how they can use known facts to derive other multiplications.

This Year 5 Multiply Numbers Mentally Using Known Facts Varied Fluency worksheet focuses children on understanding how they can use known times table facts up to 12 x 12 to mentally multiplicate larger numbers. They will look at how to apply known facts to find doubles of numbers (e.g. 3 x 8 means 3 x 16 can be calculated) then multiples of 10, 100 and 1,000 (e.g. 5 x 2 means 5 x 200 can be calculated). Finally, they will use part-whole models to calculate multiplications beyond 12 x 12. All answers are provided for ease of marking!

A reasoning and problem solving resource is also available to support deepening of this understanding.
