Our niece was having trouble with solving two systems of linear equations, since she is more of a visual learner I made her this X Y Coordinates board. There are 24 pegs total 12 blue and 12 red to plot the equations on the board. The holes in each quadrant are 14 by 14 for a total board size of 29 by 29 holes including the X and Y axis. The top board is Birch Plywood, the frame is Pine, the drawer bottom is mat-board used for framing pictures, and the pegs are cut down round toothpicks.
