Cracking the Code: Shape, Fill and Size

Pupils learn how letter codes work by finding that the first letter records shape, the second fill and the third size, then build the three-letter code for the test figure.

What this topic covers

  • Compare reference figures that change only one feature to find which position records shape, fill and size.
  • Build the test figure's code one letter at a time, rejecting options that copy a reference code.
