Decomposing numbers into pairs, Duplo activity

This week, we're working on decomposing numbers into their pairs.  For example, three and seven make ten. 

Our materials are pretty simple.  We are using the same box of magnetic numbers that I showed you in my post, Addition at the Fridge, a metal board that allowed us to have our lesson on the front porch rather than in the kitchen, and several Duplos.
