No more separate sheet of graph paper! Wow - I wish these had been around back when I was in school. This is one of the best applications of Post-It® "technology" I have seen! These small papers are sticky on two ends to adhere to paper like a "second skin" and contain that errant graphing problem, saving you from drawing number line, x/y axis, or grid on your paper or attaching (horrors!) a separate graph paper sheet. Worse yet, your children come to a graph-paper problem and "skip" it, never to return! These are handy to throw in backpack or take with you if, like my kids, yours are doing some math homework "on the run". Besides these handy graphing forms, multiplication table pads and 100-number grids are available for more elementary applications. Affix a multiplication table sheet to their desktop or worksheet for a little help before those tables are learned or use to track tables already committed to memory. Use blank 100-number grids when learning skip counting, or practicing numbers 1-100. Use numbered 100-grids to identify primes, factors, or learning by repeated addition. I'm sure you'll find even more uses.
