We decided to keep it small - ideally to be able to comfortably all build together around the table so we invited just 5 of his best school friends.
Both boys helped me with the invitations and we had quite a production going with the cutting of circles and sticking in a 6 nobble Lego brick shape, with sticky tabs helping the nobbles slightly raise.
Food wise everything had to be square (including square crisps which they were probably the most excited at for some reason!)
I cheated a little with the brownies with shop bought mini ones but 'legoed' them up by adding choc chips to make a 4 square brick.
All the food went down a treat anyway! The juice sleeves became actual sleeves and lego arms were sported for the rest of the party!
As the children arrived the first activity was to guess how many bricks in the jar.
We later counted them and the winer was only a couple of bricks out! (there were 43.)
They were then invited to sit at the table where I had prepared different tubs of lego bits - wheels, bricks, flat plates, steering wheels and people bits. The challenge was to make a car which we would then race.
The winner used the excellent technique of bigger wheels and went the longest by far!
We then went outside to play brick and spoon race -
As well as a bean bag toss into hoops with different coloured cardboard lego shapes.
Along with pass parcel, corners game (with a spinner and again using the lego cardboard shapes at each corner ) and lots of free play in the garden it was great fun! It was actually a very stress free party with very little prep too! Can't beat lego!
