This PDF can be used on the smartboard (or any projector) as tool to reinforce common core's emphasis on familiarity with spatial patterns. I set a goal, depending on your children's ability. Last year my goal was 60 in a minute, if the kids could reach that goal I gave them a pizza party. Once that goal was reached we decided on another goal (240 in 2 mins. ) Have fun with it, initially make sure that they point to the larger number and count on OUT LOUD for the smaller number. This is important so that the concept of counting on becomes INGRAINED in each child!
