Prepare and assess your children's knowledge of missing number problems by downloading and using this Year 6 Form Expressions prior learning resource. This worksheet covers objectives from earlier on in Year 6, that are linked to the objectives for this lesson, in order to prepare children for new learning. We've created three varied fluency style questions, two reasoning style questions and a problem solving question for children to put their skills to the test.

Use this worksheet at the beginning of your lesson to gauge what your class already know about forming expressions before moving onto the main skill of using simple algebra. Alternatively, this could be used a recap or further support for those who find this concept tricky. A fully explained answer sheet is provided to make marking easy or to use for peer or self marking opportunities.
