REET Level 1 study notes
Unitary Method, Percentage, Ratio and Proportion
Unitary method means finding the value of one unit first and then scaling it to the required quantity. In REET Level 1 Mathematics, it sits inside the RBSE syllabus line on unitary law, average, profit-loss and simple interest. Percentage, ratio and proportion should be taught through concrete Class 1-5 examples such as notebooks, beads, hundred-grids and rupee values, with careful attention to units and inclusive classroom participation.
Key points
- RBSE literally names unitary law with average, profit-loss and simple interest.
- Find one unit before finding many units in a unitary-method problem.
- Percentage means a comparison with 100 as the base.
- Ratio compares two quantities in the same situation.
- Proportion means two ratios show the same comparison.
- Primary teaching should move from objects to pictures to number sentences.
- Common MCQ traps include wrong unit, fixed-percent thinking and unchecked ratio equality.
- Inclusive examples keep every child inside the mathematics activity.
