Prefix Practice Worksheet
Oliver, Mei and Rawiri are preparing instructions for their robotics club. A prefix is a word part added to the beginning of a base word to change its meaning. Read each task carefully and use the clues to help the team make their instructions clear.
Decode the instructions
Prefixes can show ideas such as not, again, before, wrongly or under.

Choose a prefix that fits each meaning. Check how the prefix changes the base word.
5.Rawiri’s robot has made a mistake in its calculation. Add a prefix to calculate to mean “calculate wrongly”. Write the new word.
6.The club will test its robot before the competition. Add a prefix to view to mean “look at beforehand”. Write the new word.

- re-
- pre-
- mis-
- sub-
- under
- again
- before
- wrongly or badly
9.Oliver writes “The robot was unhappy with its test result.” What does unhappy mean here? Explain how the prefix helps you work it out.
10.Create a clear instruction for the robot using one of these prefixed words: rebuild, disconnect, misread or reread. Your sentence must show what the chosen word means.
11.True or false: In the word preheat, pre- tells you that the heating happens before something else.
