Prior knowledge.

• Find a simple fraction of an amount using addition facts

Background

Remember that students who have not reached stage 6 in the "basic facts" domain have not learned all of their basic multiplication facts, so a multiplicative strategy based purely on the numbers may not work for all students. Keeping to simpler numbers has been attempted in the activities for this reason.
