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.
Students are required to use trigonometry to calculate the length of one side of a right-angled triangle in three problems based on a ski lift, a toy sail boat and a penguin on an iceberg.
Students use their knowledge of vertically opposite angles, adjacent angles on a straight line, and angles at a point to identify unknown angles in everyday shapes.
Students estimate a subtraction problem, share their methods, discuss the rounding one number method, and then do more problems by rounding one number.
