This is a 3 part maths saga which children in your class/group will LOVE. All three lessons focus on essential skills for adding and subtracting. Lesson 1 & 2 focus purely on addition - where I encourage the children NOT to use formal columnar addition unless they have to, but try and use other mental methods like finding doubles, near doubles and using their bonds of 10s and 100s knowledge effectively. Lesson 3 involves mental additions again but with an added twist of subtraction. These lessons are so engaging and children will love them - part 3 also comes with a surprise/shocking ending. Hope you enjoy using this resource. Please rate and review.
