This is a very simple activity which can be worked out practically, by drawing pictures, or for the more able, in the head. It can be easily adapted to include higher numbers. Having read the two reviews from fellow teachers I have responded by adapting my worksheet to 3 plums, although it was easy to do after download. We use first font as an infant font in my school and I am therefore leaving that since I am sure that anyone else who downloads this will be able to change it to the font used in their schools.
Needs amending to 3 plums as the previous commenter says. Also I didn't have the font you used, so had to alter this in order to read it. I would suggest using a standard windows font that the majority of people have. A lovely idea though!
