What is it?
The more I visit primary schools and work with their teachers and pupils, the more I become convinced by the power of their bar modelling approach. Likewise, the Year 7s I teach these days seem significantly stronger in all aspects of ratio and multiplicative reasoning than Year 7s in the past.
This resource provides a wonderful introduction to the basics of bar modeling for ratio, aimed at secondary teachers. The choice of questions is superb, and really helps illustrate the power of the approach.

Consider the following three approaches:

1) Kallan and Adam share some money in the ratio 5:3.
Between them they have £240.
How much does each person receive?

2) Kallan and Adam share some money in the ratio 5:3
How much money did they share?

3) Kallan and Adam share some money in the ratio 5:3
Kallan has £240 more than Adam
