Year 6 maths: ratio, reasoning and preparing for secondary school

By Mathsonaut Team · Reviewed

Year 6 brings several familiar ideas together. A word problem may combine multiplication, fractions, ratio and measures, so identifying what each number represents becomes especially useful. Let your child draw a model and say what they know before choosing a calculation. A clear explanation gives you something specific to build on, even when the final answer is wrong.

What children explore in Year 6

  • Calculate with larger numbers, fractions, decimals and percentages.
  • Use ratio and proportion to compare quantities and scale simple relationships.
  • Solve problems involving missing values and simple algebraic expressions.
  • Reason about area, volume, coordinates and data, explaining and checking multi-step answers.

Selected topics from the mathematics programme of study for England. This is an overview, not the full curriculum or a test of readiness. Your school may teach topics in a different order.

Scale a ratio together

A pattern uses 2 blue blocks for every 3 green blocks. How many green blocks go with 4 blue blocks?

BBGGGBBGGG2 : 3 → 4 : 6
4 blue blocks go with 6 green blocks
  1. Build one unit of the pattern: two blue blocks and three green blocks.
  2. Four blue blocks is twice as many as two. To keep the same ratio, double the number of green blocks too.
  3. Two copies contain four blue and six green blocks. The ratio 4 : 6 is equivalent to 2 : 3.

A common mix-up: adding the same amount to both sides

Adding two to both numbers gives 4 : 5, which changes the relationship. Ratio scales by multiplication: double both quantities to get 4 : 6. Lay out two complete copies of the original pattern so your child can see why adding two green blocks is not enough.

Away from the screen

Design a repeating border

Draw a border made of repeated units containing two blue squares and three green squares. Build two units, then three. Record the blue and green totals in a table. Ask your child to predict the counts for five units, then check: ten blue squares and fifteen green squares.

Ask together: “What stays the same as the border grows? Is the ratio of blue to all squares also 2 : 3?”

Choose the next small step

The ratio of blue to all squares is 2 : 5, because each complete unit has five squares. Use this to distinguish part-to-part from part-to-whole comparisons. For SATs preparation, ask the teacher which topics need attention and review the method behind an error before adding more questions.
