Three fantastic activities relating to addition with regrouping. The first activity is 'Guess What Spider?' Children read the question about spiders and solve the sums to reveal the answer. The second activity is 'Spider Sort' and involves solving the sums on the shapes and attaching them to the answers on the spider webs. The third activity is a game for two players called 'The Water Spout Chase Game' which involves answering the sums and trying to reach the top of the water spout before their partner.
