Chapter 1
Handling data – Organising, categorising and representing data
1 lessons
  • Answer a question by sorting and organising data or objects in a variety of ways, e.g. using block graphs and pictograms with practical resources; discussing the results; in lists and tables with practical resources; discussing the results; in Venn or Carroll diagrams giving different criteria for grouping the same objects+10
Chapter 2
Geometry – Position and movement
1 lessons
  • Use everyday language of direction and distance to describe movement of objects+10
Chapter 3
Geometry – Shapes and geometric reasoning
3 lessons
  • Name and sort common 2D shapes (e.g. circles, squares, rectangles and triangles) using features such as number of sides, curved or straight. Use them to make patterns and models+10
  • Name and sort common 3D shapes (e.g. cube, cuboid, cylinder, cone and sphere) using features such as number of faces, flat or curved faces. Use them to make patterns and models+10
  • Recognise basic line symmetry+10
Chapter 4
Measure – Length, mass and capacity
3 lessons
  • Compare lengths and weights by direct comparison, then by using uniform non-standard units+10
  • Estimate and compare capacities by direct comparison, then by using uniform non-standard units+10

  • Begin to use the +, – and = signs to record calculations in number sentences+10
  • Understand that changing the order of addition does not change the total+10
  • Add a pair of numbers by putting the larger number first and counting on+10
