Teaching and Group Activities for Understanding
Day 1 Teaching
Children each draw a quadrilateral, then discuss similarities and differences. Name and explore properties of quadrilaterals using an online activity.
Group Activities: T with Y5
Y5 -- Tear the four vertices from a quadrilateral and arrange around a point to find the total angle. Investigate diagonals of quadrilaterals;
Y6 -- Use a sorting tree, Carroll or Venn diagram to sort quadrilaterals. Make a range of quadrilaterals using art straws and identify features.
Day 2 Teaching
Children write facts about shapes, then use facts to guess a mystery shape.
Further Teaching with Y6
Discuss radius, circumference and diameter. Describe relationship of diameter and radius as a ratio (2 to 1, 2:1).
Group Activities: T with Y6
Use the in-depth problem-solving investigation for this unit ‘Polygon dissections’ as today’s group activity.
Or, use these activities:
Y5 -- Investigate how many different polygons can be made by drawing five equilateral triangles next to one another.
Y6 -- Draw circles, measure diameters and circumferences with string and work out ratio (Pi is introduced).
