Dear Parent/Carer,
It isn’t practical for the answer sheet to MENTAL MATHS 5 a day to be bound into the back of the book, as you would be wanting to use it at the same time as you are asking questions of your child. On the other hand, as it is provided to you as a loose sheet, it could easily get lost. We have therefore uploaded it to our website so you can have it ready to hand on your phone screen, tablet, laptop or PC when you are ready to work through your daily 5 minutes with your child. We hope you find this a convenient option. Please click here to open the answers as a PDF or see below.
