Year 6 / Mathematics / Geometry and measure
Area, volume and circles: structured theory, worked examples, answered practice, and a mastery checklist for Year 6.
Unit
The essential chapter ideas in a clear sequence before practice.
Mathematics
Start from the board specification and work topic by topic before full papers.
The structure follows the official textbook layout and is used to organise study.
The areas that usually create mistakes or need extra revision.
Mark every given on the diagram and state the target clearly. Start from a relationship that connects exactly those quantities.
Every geometric step needs a property, theorem, or definition. A result without justification is not a complete proof.
Length, area, volume, and angle use different units. Round only at the end and keep sufficient intermediate precision.
Draw and label every given before choosing a property or formula. Finish with estimation, an inverse operation, or substitution as a check.

Mathematics
Follow the method step by step and check why every step is valid.
A rectangle is 7 cm long and 6 cm wide. Find its perimeter and, where covered, its area.
Perimeter 26 cm, area 42 cm².
Explain “triangles” in your own words and use a picture, objects, a table, or a simple measurement to support it.
A complete explanation connects the correct idea, a clear representation, and a sensible check.
Area, volume and circles
Eight graded tasks from core fluency to exam-style application. Work independently before opening a hint or answer.
Calculate 4 + 6 and show two representations connected with “triangles”.
Use a number line, place value, or objects.
4 + 6 = 10. Valid representations include number-line jumps and grouped objects.
3 equal groups contain 7 objects each. Find the total and write an addition and multiplication statement.
Add 7 a total of 3 times.
7 + 7 + 7 = 3 · 7 = 21.
Continue 3, 8, 13, ... for three more terms and explain the rule.
Check how much each term increases.
18, 23, 28; +5.
A rectangle has sides 6 cm and 2 cm. Find its perimeter and explain why four sides are counted.
Opposite sides are equal.
Perimeter = 6 + 2 + 6 + 2 = 16 cm.
Out of 36 objects, 9 are shaded. What fraction is shaded and how does it simplify?
Put shaded objects over the total.
9/36 = 1/4.
The measurements are 5, 6, 5, and 6. Find the greatest, least, and range.
Range = greatest value minus least value.
Greatest 6, least 5, range 1.
Anna has 24 cards, gives away 8, then shares the rest into 2 equal groups. How many are in each group?
Subtract first, then divide.
24 - 8 = 16; (16) : 2 = 8.
A learner says 4 + 5 = 10. Find the error, correct it, and check the correction.
Check with a number line or inverse subtraction.
4 + 5 = 9; 9 - 5 = 4.
Area, volume and circles
Six distinct assignments from core fluency to challenge, each with an estimated time, hint, and answer guide.
Homework 1: Calculate 7 + 2 and show two representations connected with “triangles”.
Use a number line, place value, or objects.
7 + 2 = 9. Valid representations include number-line jumps and grouped objects.
Homework 2: 4 equal groups contain 3 objects each. Find the total and write an addition and multiplication statement.
Add 3 a total of 4 times.
3 + 3 + 3 + 3 = 4 · 3 = 12.
Homework 3: Continue 6, 12, 18, ... for three more terms and explain the rule.
Check how much each term increases.
24, 30, 36; +6.
Homework 4: A rectangle has sides 9 cm and 3 cm. Find its perimeter and explain why four sides are counted.
Opposite sides are equal.
Perimeter = 9 + 3 + 9 + 3 = 24 cm.
Homework 5: Out of 25 objects, 5 are shaded. What fraction is shaded and how does it simplify?
Put shaded objects over the total.
5/25 = 1/5.
Homework 6: The measurements are 8, 2, 8, and 2. Find the greatest, least, and range.
Range = greatest value minus least value.
Greatest 8, least 2, range 6.
35 minutes / 30 marks
A timed, full-mark self-assessment with model-answer guidance.
Start the timer when ready, work without notes, show every step, and open model answers only after finishing.
