Last summer I spent a few weeks hosting a summer math camp for a small group of third graders. We practiced and reviewed a ton of important math concepts, but there was one thing they struggled with in particular that caught me off guard: rounding. In our review of large numbers, I expected to have to focus on adding and subtracting with regrouping. Rounding, on the other hand, was supposed to be a simple review. This turned out to be quite a struggle, however, so we spent a good deal of time on it. If your kids are struggling with rounding as well, this Swim Meet Printable Rounding Game may be just the thing you need to practice rounding this summer!

How to set up this printable rounding game:
Included in this download are a color and black and white game board, printable instructions, swimmers to use as game pieces, and a set of game cards (36 cards).
No other materials are necessary to play!
Simply print the game board of your choice, as well as the swimmers and cards. I suggest printing on card stock for durability, and so that the game cards will not be see through.
You may want to laminate all the game pieces as well so that it can be used again and again.
Then, cut out the swimmer game pieces and the cards.
Place the cards in a pile face down, and place a swimmer for each player on the side of the pool to start the game.
How to Play Swim Meet Rounding Race:
The goal of the game is similar to that of a swim meet. Each player is trying to “swim” to one end of the pool and back again to win the race.
To play, the first player draws a card and rounds the number according to the directions on the card.
(The cards directions include rounding to the nearest ten, hundred and thousand).
If the number rounds up, the player moves forward in their lane on the game board.
If the number rounds down, the player does not move at all.
If they round incorrectly, the player moves back a space in their lane (unless they are at start, in which case they stay at start).
To Win the Game:
The first player to make it down to the end of their lane and back to the edge of the pool (a total of ten spaces on the game board) is the winner!
This game would make a fun math center if you’re a classroom teacher!
If you’re looking for another way to work on rounding practice, play this simple game with a deck of cards to work on place value, compare large numbers and round large numbers.
