I am planning on playing with the students. They will have blocks at their desks and they will all make it and then call one student up to show the class how they made the number. Ask students if anyone made it a different way. Take anecdotal notes as you walk around as to who can make the number in base ten form with the manipulatives.

If we made one class set and shared or if someone already has a set we could pass these around.
