post box

i've bought them lots of envelope to encourage them to write, they been busy writing letters to their grannies and friends.

from there i got the idea of making them use the knowledge of math using rulers and measurement.

i give them small boxes and with the rulers and the envelope, they need to measure the length needed to make the post box hole so that the envelope will fit in there.

and not to forget, the need to make it look like the post pox so that the postman will know it's a post box!

they got tones of ideas!
