What is on the worksheet

Every sheet for this lesson has a short teaching box and 12 questions that get gradually harder: 8 fluency questions, then 4 reasoning questions that ask pupils to explain or choose. A writing challenge follows. The questions use the same styles as the key stage 2 grammar and punctuation test (circle, underline, tick, fill the gap, add punctuation, rewrite, explain). They are written for this website, not copied from past papers.

All the answers are on the last page of the same editable Word file. New questions are made every time, so you can print a different sheet for every group or for homework. The same sheet code always gives the same sheet.

Writing challenge: Make a list of eight words that start with sub- or inter-. Write a sentence for three of them.

Pupil target: I can add sub- and inter- to words.

The PowerPoint

A 20-slide lesson deck for the same lesson: a starter that revisits earlier learning, key words, an I do and a You do question on each slide with a countdown timer, answers that appear one click at a time, and a challenge. Download the adding sub- and inter- PowerPoint.
