What the class will do
Match pairs · 6 challenges
Find a meaningful base
Connect each word to its meaningful base. Explain how the meaning survives the added part or spelling change.
Sort into groups · 8 challenges
Separate look-alike families
Read each complete phrase. Decide which base meaning it belongs to and group it with that family.
Choose and explain · 16 challenges
Weigh a family explanation
Choose the explanation supported by meaning and spelling. First compare with a partner, then cite the evidence.
Using it in class
Everyone proposes a base and explains its meaning before the representative acts. First five matches: 8–12 minutes; all 30: 35–45 minutes with brief talk. The final choices compare reasons, spelling changes and counterexamples. Recognition here supports, but does not assess, independent writing.
Give everyone time to think and discuss before one pupil acts at the board. The class explains and confirms together; hints and explanations stay until you move on.
Use an up-to-date browser on a computer connected to a whiteboard or shared display. Touch, mouse and keyboard; optional audio and reduced motion. No pupil accounts or personal devices.
Choose from 5 challenges up to the full activity. Discussion determines the duration: you set the pace.
A look inside the activities
Match pairs
Connect each word to the familiar base that carries its central meaning.
unhappy
redraw
careless
Match with:
happy
care
draw
Explanation and discussion
Unhappy relates to happy, redraw to draw and careless to care. The added parts alter the meanings but retain a link to the base.
How can related words have different or opposite meanings?
Sort into groups
Group by the base meaning: giving care, or carrying something.
a careful check
caring for a seedling
carried to the hall
a carrier holding boxes
Groups: CARE · CARRY
Explanation and discussion
Care and carry look similar but supply different meanings. Caring loses the e of care; carried and carrier change the y of carry.
What evidence besides the letters car separates these families?
Choose and explain
Why is unhelpful a defensible member of the help family?
Its meaning concerns not giving help, and it retains help.
It begins with the same two letters as unhappy.
Every word beginning un- belongs to one family.
Explanation and discussion
Unhelpful retains help’s meaning while adding a negative description. A shared prefix alone would not link every un- word to help.
What connects helpful and unhelpful despite their contrasting meanings?
