Ratios, rates & percent
Ratios, rates & percent is a building block of mathematics. Before tackling harder problems, mathematicians make sure the foundations are solid — and that is exactly what this lesson does. We start with the ideas you already know and connect them to ratios, rates & percent step by step.
The key to ratios, rates & percent is understanding why each step works, not just memorising rules. When you work through an example, ask yourself: what changed at each step, and why was that allowed? This habit turns procedures into real understanding.
You use ratios, rates & percent more often than you might think — in shopping, cooking, sports statistics and planning trips across Canada. By the end of this lesson you will be able to explain ratios, rates & percent in your own words and apply it to everyday problems.
Learning goals
- Explain the key ideas of ratios, rates & percent in your own words
- Apply ratios, rates & percent skills to everyday Canadian examples
- Reflect on what you learned and set a next step
Learning together
Warm-up (10 min)
Mental-math warm-up: three quick questions that review the skills ratios, rates & percent builds on. Discuss strategies aloud.
Teach (20 min)
Introduce the key idea of ratios, rates & percent with one worked example on paper or a whiteboard. Think aloud through each step, then do a second example together.
Guided practice (15 min)
Learner tries two ratios, rates & percent problems with support. Ask "what comes next?" rather than giving answers.
Independent practice (10 min)
Learner completes the practice problems in Section B of the worksheet alone.
Wrap-up (5 min)
Exit question: "Explain ratios, rates & percent to me in one sentence." Note anything to review next lesson.
