My school has purchased Numicon for all of our classes recently, lucky us! We are all trying it out. But what does this have to do with outdoors, you may ask? Well I found two links on the Numicon site I thought I would share with you.http://www.numicon.com/free_resources/teaching_support_resources.aspx
I had some other ideas like hiding number bonds around in little bags and the children have to check the bag to see what they have and put in the correct place.
How have you taken numicon outside? Let me know.
