- Distinguish boundary length from enclosed area.
- Use rectangle, triangle, and trapezoid formulas.
- Find missing dimensions and solve composite-shape problems.
Worked example
A rectangle is 6 cm long and 4 cm wide. Perimeter = 2(6 + 4) = 20 cm. Area = 6 × 4 = 24 cm².
How the Ladder Works
Six levels run from Warm-Up to Mastery. Warm-Up has five questions; later sets grow to eight or nine depending on the topic. Clear a level with at least 80% first-try accuracy. Every level is available from the start, and retries produce fresh questions.
Hints and worked solutions support practice. Grades 5–8 is a guide, not a restriction.
