How to use it

Try the first question together so the format is clear. Then let your child work through the rest, showing their thinking on the page. It is one of the harder sheets for Grade 9, best once the basics of the skill are secure.

Tip for grown-ups: Read each sentence aloud with a hum for the blank, then try each word bank word in it.
