Number Detectives

We enjoyed playing the Number Rack Detective game with partners today.
We were given a number to make using one or two strings on our number racks, and kept it hidden from our partner.

Next, the Detective partner listened to the Clue Giver partner give a clue about how many s/he moved on one of the strings.  The Detective had to then figure out how many beads were on the other string.

We're getting to be stronger mathematicians every day!
