How to use this resource
- Model pack -> repack with a bag: pack it, empty it, then pack it again. Keep the base word visible.
- Use the supplied example or task brief. Let the learner respond through writing, drawing, discussion or their usual communication method.
- Review the answers or criteria below. Can the learner explain the whole word through its prefix and base, rather than just spotting matching letters?
What is in the printable?
Word bank: pack / repack; fair / unfair; agree / disagree. A prefix is added at the beginning. In these examples, re- means again; un- means not; dis- in disagree marks an opposite meaning.
- Explain repack using the word pack.
- Explain unfair using the word fair.
- Explain disagree using the word agree.
- Complete: I read the page again. I ______ it.
- Use one word from the bank in a sentence that shows its meaning.
Make it easier or add challenge
More support
Use just pack/repack and fair/unfair. Read each word aloud and offer a choice between two meanings.
More challenge
Try undo and redo. Explain why the same base can take different prefixes; find a word that merely starts with the letters re.
What to look for
Can the learner explain the whole word through its prefix and base, rather than just spotting matching letters?
Teacher answers and suggested responses
1. Pack again.
2. Not fair.
3. Have a different opinion or not agree.
4. Reread.
5. Open-ended: the context must show the chosen meaning. Do not assume every word beginning re has this prefix.

Try another activity
Deliver individually or in a small group
Choose one learning aim from this activity. Model one example, work through another together, then give each pupil a turn with a fresh example. In a group, ask everyone to think or show a response before sharing; one confident answer does not show what the whole group understands.
Keep the task’s more-support option available. Allow the usual communication tools, practical materials or drawing where these preserve the learning aim. Reduce the number of examples if needed, rather than rushing through the sheet.
What progress should I look for?
Can the learner explain the whole word through its prefix and base, rather than just spotting matching letters?
Note the example used and whether the response was independent, followed a general prompt or needed a model. Try a different example on a later occasion and look for clearer reasoning or less support on a comparable task. Use these observations to plan the next teaching step.
