I use this simple graphic organizer during Calendar Time to solidify the 1 more/1 less and 10 more/10 less concepts for math number sense. Please take a moment to rate my work. I'm new to tpt and would love to know if I'm on the right track with my products. Thanks so much!
P.S. Here's a nifty trick I always use. Slip it into a plastic page protector and pin it to your calendar wall. Now fill in the blanks with a dry erase marker. Then just wipe it off for the next day, or to do another one. :)
