Up arrow increases ones by 1. Right arrow increases tens by 1. Down arrow increases hundreds by 1. Space bar zeroes all numbers. This is a lesson for Grades 1 & 2 students - Hook up three pressure switches to a Makey Makey. (You can make these out of cardboard, masking or duct tape, sponges, and tin foil or copper tape.) - Have the students figure out which place value each switch increases and put them in order. - Give students a three digit number and have them add the correct number of 100s, 10s and 1s to arrive at that number.
TEAM AWESOME!
