Magnetic Demo -NFM
This magnetic set mimics the 2 bar NFM with movable white and red beveled beads. Use this at the front of the class on any magnetic surface to demonstrate addition and subtraction. 10 red and 10 white magnetic pieces make it easy to display concepts on a magnetic board. The set comes with two magnetic bar sheets, each sheet is 17 x 8 and beads are 3 x 1.38.
