Use this Year 1 Adding '-s' Prior Learning worksheet to assess children's understanding of the single nouns before moving onto adding '-s' to show plural. An answer sheet is provided in a child-friendly way to allow for peer or self-marking to make marking and misconception checking quicker and easier.

This worksheet could be used as a prior knowledge check before the lesson or with small groups of children who may be struggling or simply need a little extra support with suffixes.
