For this presentation I used a selection of different flowers (some small, large, round, long, scented etc) but anything that you can describe by more than colour would work just as well (like a group of different cakes - yum)
Start by bringing out the large blue pyramid/triangle and ask them if they can remember what it represents.
Recap the adjectives you used in the first discussion.
Bring out the flowers and ask them to find the small flower and the big flower - once they have done this write the phrase under each flower and ask them to identify the descriptive word/adjective.
Ask them to write an adjective for each flower but this time avoiding colour descriptions.
