# Practicing +10 and -10

Ever wonder why we practice the patterns of +1/-1 and +10/-10 using a hundred chart? Well, we’re adding and subtracting tens and ones, so it actually supports place value understanding. We add ten to the numbers when we move down one row because it’s the same as moving forward ten spaces. Ten ones equal a ten.

Here’s an easy little game for practicing +10 and -10 called Row, Row by Ten. The game comes from a wonderful book that was recommended to me, Common Core Math in Action (K-2), by Catherine Jones Kuhns and Marrie Lasater. It’s easy to make and the kids love playing it. Basically, each player starts on the top row of the 120 chart. It really doesn’t matter what number they start on because they are just moving up and down in the column, so starting on 8 has no advantage over starting on 2. On a player’s turn, they spin the spinner. If they spin a +10, they move to the number that is 10 more. Be sure that students verbalize their move,ย “Ten more than 8 is 18.” If they spin a -10–you guessed it–they move to the number that is 10 less. If they spin the -10 on their first tun, they just stay on their start space. The winner is the first player to reach the bottom of the chart.

Package it all up in a gallon plastic bag (trim a little off the 120 chart for it to fit) for easy storage. Grab your freebie here. Enjoy!
