FrogHop Magnetic Number Line Set Addition Subtraction Learning Aid Classroom Whiteboard Math

Make movement on a number line easy to see with the FrogHop Magnetic Number Line Set. Each friendly green marker points in both directions, with a minus symbol on the left and a plus symbol on the right to reinforce moving backward for subtraction and forward for addition.

MINIMUM AGE
Ages 6+.

Use one marker for a whole-class demonstration or place several markers on the board to compare starting points, show different solution paths, and discuss where each jump lands. The four matching markers hold securely to a magnetic whiteboard and store together in the included blue case.
