Introduction
Children are introduced to the concept of mathematical coding through practical activity, transforming shapes on a grid.
Episode 1:
Children explore making shapes on a pin board, following a rule. They struggle to describe the transformed shapes in terms of both position and movement. They discuss how they recorded the moves and agree a two-part coding system.
Episode 2:
The class discuss a more complex transformation. Children work in pairs to explore how many possible shapes can be generated by the new move and apply the coding system to record their findings as they work. They discuss and identify a rule for the two-part move.
Episode 3:
Children predict the number of moves needed to create a range of given shapes and then test to find out. They give instructions for more complex transformations. Finally they look for patterns and make generalised statements.
Reflection
Aims
  • Children understand the need for a coding system that can describe position and movement
  • Children create, formalise and then use, a coding system to transform shapes
  • Children know that within maths there are certain rules, which can be worked out by looking for patterns
  • Materials
    Supplied

  • Resource Sheet A showing 5 x 5 pin board grids
  • Resource Sheet B showing a range of shapes on dotted paper
  • Not Supplied

  • A pin board for each pair (ideally 5 x 5)
  • • Two elastic bands for each pin board (two different colours)
  • Before you teach
    Photocopy Resource Sheets A and B, one per pair
    Vocabulary
    Shape, side, corner, vertex, horizontal, vertical, straight, square, oblong, rectangle, quadrilateral, grid, pattern, rule, code, system, names of familiar quadrilaterals eg parallelogram, trapezium, etc
