Teaching and Group Activities for Understanding
Day 1 Teaching
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. Then fold another piece of paper into 1/3s.
Use the in-depth problem-solving investigation ‘Halving’ from NRICH as today’s group activity.
Or, use these activities:
-- Identify whether shapes are correctly divided into halves, quarters or thirds.
-- Fold shapes into halves, quarters or thirds.
Day 2 Teaching
Draw a square; divide it into 1/4s. Shade 3/4. How much is coloured? Record ‘three quarters’ and 3/4. Ask children to draw a square on their whiteboard and to colour in 3/4 in a different way to yours. Repeat for an oblong and a circle. Show a variety of children’s whiteboards.
Repeat for thirds, using a square, oblong and a circle.
-- Shade 1/4s or 1/3s of shapes.
-- Design then play snap or pairs with fractions and shaded shapes.
