Students explain how they can work out how many striped or shaded beads are needed for a number of repeated 'sets', and identify the number of striped and shaded beads for given numbers of sets.
Student solve addition problems where the missing value is located in different positions. This may mean that students transform the problem into a subtraction one. Students reflect on the easiest and hardest problems, and explain their choice.
