At this level, pupils will solve harder problems with higher mathematical knowledge, they will be able to
- construct appropriate bar models for ratio situations and apply the Unitary Method;
- relate ratio situations to fraction and percentage situations for the same Ratio Approach;
- apply cumulative difference for mathematical deduction s to deal with distributive property situations.
The learning is running together with the examples and exercises in the following units.
Unit 4: Ratio Problems.
Unit 5: Fraction Problems
Unit 6: Percentage Problems
Unit 7: Distributive Property Problem
