We have had a super time practising shapes, colours and sorting with this great puzzle. I picked mine up Teachers Trunk for less than $20.
I know it will get used year after year regardless of the season.
It is a perfect gift for a 2-4 or a great -30 indoor activity to do.
(I scented mine slightly with a little vanilla extract......just a touch, too much would make the plastic sticky/too temping to lick!)
