Print on A4 portrait: every page carries the sheet twice, side by side, so you can cut down the middle and two pupils each get a half to stick in their books. Every question sits in its own box and pupils write their answers in their book. The answers follow the questions in the file: the same sheet again with every answer in red. It opens in Word, Google Docs, Pages and LibreOffice, so you can change numbers, delete questions or add your own. There is no scaffolded version of this step yet.

What is on each sheet

  • Fluency: eight questions that start easy and get harder, with the key skill of the step practised in different ways.
  • Reasoning: questions with pictures, tables and number lines (spot the mistake, true or false and explain, puzzles with one answer, an open-ended task).
  • Answers in the same file: the sheet again with every answer in red, so there is only one file to download.
  • Boba characters give the instructions in speech bubbles. They are decoration only.
