 Mental Maths

Mental Maths Questions

The first ten minutes of each lesson is spent learning and practicing strategies to assist in solving mathematical problems in our heads, as opposed to using a written method.  Below are a number of questions that are representative of those we look at, and of those that appear in end of year tests.  If you want to give a friend or your child practice at mental mathematics, use these questions or tweak the numbers to create your own mental maths test!
