Lesson 3: Let’s solve ratio problems

Students will apply their understanding of ratios to problem-solve during an activity that involves calculating how many exotic plants each botanist has found.

Lesson 8: Let’s solve formulae with two unknowns

In this lesson, students will solve equations with 2 unknowns. They will use inverse operations, bar models, problem-solving skills and substitutions to determine variables. This lesson will utilise all their knowledge from this unit and help to develop their flexible thinking skills. Students will solve a code cracker.
