Springin' Into Adding and Subtracting 10's Game

I think I've said before that our new common core aligned math curriculum is a bit tough this year. Next year will be better, but this year has been slightly difficult due to the switch (our students just don't have the background knowledge needed yet). However, we're hanging in there, and I am impressed with some of the strategies my students have picked up. One of the strategies enVision teaches our students to use is to be able to use mental math to add and subtract 10's from a given 2-digit number. We've taught the kids how to do this by skip counting on/back by 10's, we've taught them using place value blocks/cube towers/ten frames, and we've taught them by using the hundreds chart. Students are realizing that this strategy makes computation easier and faster!

I created this game for students to practice this strategy in order to increase their computational fluency. It will be going in the math center after introducing and practicing with it! Students should be able to solve the problems using mental math (of course they can get manipulatives if they need/request), but I am also having them write the problems on scrap paper so I can see how they're doing with it. To play, students place their game markers on start. They will then flip a colored counter/chip. If it lands on red, they will move forward 1 spot. If it lands on yellow, they can move 2 spots. The students must solve the problems for whatever spaces they land on. The first one to the end is the winner! If a student lands on a space that has a ZOOM arrow, he/she can cross the arrow over to the space on the other side. Enjoy the free printable game, and if you have time, please leave me some bloggie love if you download (just click the picture)! :-)

  1. I am so excited to try this game!

  2. Our 4 year old saw the colorful pictures and wanted to try this game. He is writing his own numbers without any fuse and doing double digit math. Thanks

  3. Thank you so much for the game. I wasl going crazy trying to find some kind of game to reinforce this concept. Thank you so much for sharing!
