**The repeated aggregation structure for multiplication **

**Teaching Point**

The key language to be developed in the repeated aggregation structure of multiplication includes: so many lots (sets) of so many, how many (how much) altogether, per, each.

*Repeated aggregation* (or repeated addition) is the elementary idea that multiplication means ‘so many sets of’ or ‘so many lots of’. If I have ’10 sets of 3 counters’ then the question, ‘how many counters altogether?’ is associated with the multiplication, 3 x 10 see Figure 8.
