Out of all the wooden toys that he had, I enjoy this the most. It's called Versa Tiles. You can see it in the here: http://www.voilatoy.com/products/activity_s520e.html
It is a set of colourful 28 blocks. It has a quite a number of cardboard patterns and you need to place the blocks based on the colour and pattern in the cardboard. As you progress higher, there would be frames which you need to use the blocks to fill in the picture. It is not very easy. I would only know how to put the blocks based on the colour and pattern given.
|This is how you place the blocks on the cardboard provided.|
You would just need to match the shape and colour.
|This is how it looks like after you have placed all the boards in the base.|
|There are other cardboards like this.|
You need to place the blocks in the outline to
form the picture. It's not easy for me.
|The answers are provided here to show which|
shape of block you need to use to form the picture.
There are about 9 or 10 cardboards, each double sided.
So, lots of pictures to do.
