Math tile mania!

In first grade they have an activity called 'math tiles'.  There are 20 sheets in a packet that they work through one by one until they mark off every sheet on their list, then they move onto another packet.  In Brooke's class this year there is a group of competitive little math buggers, and they are going nuts!  The class next to us is on packet 4 at the highest...Brooke is on packet 34!  Our teacher says this is the highest she's ever had a class go.  Some of the packets are SO hard, it takes some of Mommy's thinking power to get us through. They are so tricky!  Yesterday she got lucky and brought home a not-so-hard packet (number 34), and she whizzed through the entire thing in less than an hour.  Bring on packet 35!
