Practice rounding numbers to the nearest ten with this free online memory-style matching game, Match Around 10’s by Math Nook.
A deck of cards is shuffled and spread out to create 4 rows of 4 cards. Click any two cards, over and over until you see an even 10 and a number that can be rounded to that 10. Once a match is made, the cards are removed from the playing area, and the game is won when only 2 cards remain.
You can try to beat your own high score with this rounding practice game, or email a friend to challenge them to beat your score. A great way to practice a valuable math skill in a competitive spirit.
There is also another Math Nook game to practice rounding to the nearest ten — Which One Rounds?
For this game, you can have the volume turned up in order to hear the computer ask, “Which One Rounds to __?” in order to choose the correct one of four numbers. There is also a line of text appearing in the bottom left corner posing the same question — in case the sound is a problem.
