Students use coloured beads to make repeating pattern. They then identify the colour of specific beads in the pattern and explain how to work this out.
In this task students build the next two models of a spatial sequential pattern and then use their results to predict subsequent patterns and give general rules for these in words and in equations.
This practical task assesses students' understanding of the different features of the vertebrate groups. Students need to identify the larger group that their animal card belongs too, then work with other students with the same group to write down all the features of that group.
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.
