Geyer has many dry erase tools to make your lessons easier to understand and more fun. With the demonstration tools, your lecture will gain great visuals that grab students attention. The charts come in static cling, low-tac, and magnetic. These features allow the chart to be reused and moved with ease. Some of the charts include polar graphs, blank clock face, quadrants, number boards, multiplication chart, addition/subtraction chart, unit circle, class schedule, and so much more! The magnetic demonstration tools are another great resource to have in the classroom. During a math lesson use one of these to quickly and cleanly draw shapes without worrying about what your freehand drawings look like. These tools come in circular protractor, semicircle protractor, ruler, triangles, and compass. Since they are magnetic, they will hold to the board as you draw.
