Activity Instructions

Label the mat from 100 to 500, placing a multiple of 100 every five hash marks. Place a bean bag (or any marker) at a hash mark and have students figure out what number it is at. They will need to first find out how much each hash mark equals. By trial and error, help them determine how many each mark is counting by different multiples (1, 2, 5, 10, then 20).
