Subtraction using a number line

By the end of Year 1, children are expected to be confident at using a number line to answer addition and subtraction sums, by counting the 'jumps' forward and backward along the line. In the video to the right, Victoria is learning how to use the number line to subtract 1 from a given number. The skills she uses here will support her in being able to use this method to complete more difficult calculations later on.
