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 1, best once the basics of the skill are secure.

An answer key comes with it as a separate page that grown-ups download after signing in.

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

Done on paper? A grown-up can record it on the child's page in PlayOwl; downloading alone doesn't count as finished.
