Now children can represent the number of the day in lots of different ways—with our jumbo magnetic write & wipe chart! Simply write a number at the top of the chart…and invite students to draw it as a series of tally marks, write it in word form, mark it on a number line and more. Then just wipe the chart clean to start again! Reusable chart adheres to any magnetic surface and measures 22" x 28". Write & wipe markers sold separately.
