Splitting shapes into equal parts (age 7+)
Partition circles and rectangles into two, three, or four equal shares; describe shares as halves, thirds, and fourths; recognise that equal shares of identical wholes need not have the same shape
Suggested ages 7–8
Learning journey
Your child is discovering fractions as parts of a whole — understanding halves, thirds, and quarters, placing fractions on number lines, and beginning to add and subtract simple fractions.
Evidence of understanding
- Partition a circle into 3 equal parts and label each 'a third'
- Partition a rectangle into 4 equal shares in more than one way
- Explain that two different-looking shares can still be equal in size
Assessment prompt
If you cut a rectangle into thirds in two different ways (three strips vs three squares), can Splitting shapes into equal parts (age 7+) recognise that both give equal thirds — even though the pieces look different?
