This clip looks at different items in a sports shop. We can't count the difference in size, shape or position, but we can count the difference with numbers. We then see how to work out the difference between numbered floors in a shopping centre. There is a song to finish.
Using the magic boot idea from the clip, place large numbers up to 5 on the carpet and choose children to stand on one of the numbers. Ask the rest of the class the difference between the number the pupil is standing on and another number. Ask the pupil to jump in his or her magic boots as the class count the difference. Repeat with other numbers and different pupils going forwards and backwards.
