Maths Year 1/2 Autumn Fractions and Multiplication

Each unit has everything you need to teach a set of related skills and concepts.

Understanding halves and quarters (suggested as 2 days)

Planning and Activities

Day 1 Teaching
Discuss colouring mats so that half is green and half is yellow. Stress that halves are equal.
Further Teaching with Y2
Demonstrate halves and quarters by asking children to fold a piece of A4 paper into first 1/2 and then into 1/4s. Stress that these are equal parts of the shape, label each part.
Group Activities: T with Y2
Use the in-depth problem-solving investigation ‘Same shapes’ from NRICH as today’s group activity.
Or, use these activities:
Y1 -- Find half of shapes in different ways, including folding.
Y2 -- Identify whether shapes are correctly divided into halves or quarters; some children will fold shapes into halves and quarters.

Day 2 Teaching
Discuss colouring mats so that 1/4 is red and 3/4 is blue. Stress that quarters are equal.
Group Activities: T with Y1
Y1 -- Design party mats for Maisie by finding and shading quarters of shapes.
Y2 -- Find 1/4 by folding; shade 1/4s of shapes in different ways. Some children begin to find quarters of quantities.

You Will Need

  • A4 paper (including one pre-painted)
  • Square of paper and yellow, green, red and blue paint
  • Pre-cut shapes (circles, squares, semi-circles, equilateral triangles)
  • ‘Shapes divided into two or four parts’ sheet (see resources)
  • ‘Shapes to cut out and fold’ sheet (see resources)
  • Rulers
  • Additional activity sheets (see resources)
  • Colouring pencils


Day 1
Y1: Make party mats for Teddy by colouring halves of shapes.
Y2: Colours 1/2s and 1/4s of shapes.

Day 2
Y1: Colour 1/4 and 3/4 of shapes; recognise shapes that are not divided into equal quarters.
Y2: Match fractions to visual representations.

Mastery: Reasoning and Problem-Solving


  • Draw a line through each shape to cut it in half (including trapezium, octagon, oblong: see download).
  • This strip of paper has been folded into four parts. Is each part a quarter?
  • How many quarters in 1 whole cake?


  • Fold an oblong into quarters. Can you take an identical oblong and fold it into quarters in a different way?
  • Draw around 8 squares in a row in your maths book. Now colour three quarters of this ‘strip’.
  • This strip of paper has been folded into four parts. Is each part a quarter? Explain your ideas clearly.

In-Depth Investigation: Same Shapes
Investigate how a selection of irregular shapes can be cut in half to make two shapes the same shape and size. Same Shapes from
