Tricky examples like whales, bats and penguins come up often.

Frequently asked questions

Why is a whale a mammal?

It breathes air with lungs, is warm-blooded and feeds its young on milk, even though it lives in the sea.

Is there an answer key?

Yes. Every worksheet ends with an answer key on its own page. Switch it off if you’re giving the sheet as a test.

Can I choose the kinds of questions?

Yes. Switch each section on or off (matching, fill in the blanks, true or false, multiple choice and more) and choose how many questions go in each.

Can I print it in black and white?

Yes. The worksheet uses light tints that print clearly in grey, or pick the grey colour theme.

Will every worksheet be the same?

No. Each tap of “New worksheet” picks a different mix of questions from the topic’s question bank, so you can give different versions to different students.
