We have been working very diligently on teen numbers, what they look like, how we print them, how we make them, how not to be confused by them . . .
Here the students are playing Grab, Move, Show. The students GRAB a handful of the gems, place them on one side of the paper, MOVE them to the other side as they count, and SHOW the number. The skill I am trying to teach is to MOVE the items in order to count them properly.
And they learn to grab more or less as the goal is to get a teen number. :)
I just received a grant for a light table and science items, YEAH, so I am using my light table here in math to work with tangrams. The children are trying to make a square using all seven pieces. Or at least different shapes using a couple of pieces.
