Jumping backwards along the number line

We played a game using a number line. First, we made the number line by starting at 20 and counting back. Then we started at 20 and rolled the dice to move back along the number line, trying to get to 0. Miss J modelled counting back as we jumped and some of us worked out which number we would land on by looking at the number line. It was tricky, so we will keep practising!
