-- number race dice game for kindergarten, common core K.OA.3, decompose numbers, math center --
Number Race includes three pages (versions) of the same game for differentiating instruction. Each page is legal sized and landscape orientation. This game is a great way to teach and reinforce California Common Core Standard K.OA.3: Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
Students can work in pairs or individually. When in pairs, I tell students that they are not competing but working together on the same game to see which number is the winner.
As Teammates: Each student has own paper. Student #1 rolls two dice and both students mark the bottom box (with an "X") of the corresponding number. Student #2 then rolls and both students mark appropriate box. The first number to get rolled for the fifth time wins and students color the star in the box and the game is over.
As an Individual: Played as above, but single students is the only one to roll the dice.
Page 1 (color): Use this version to make file folder games, laminate and use as write-on/wipe-off, or use objects to "mark" squares and remove them when each game is over. (See game-playing options below.)
Page 2 (blackline): Dice pairs (with dots) are shown below each number so students can see some of the pairs of numbers that make up each larger number. Lots to learn here (e.g., What is the smallest/largest number that can be rolled using two dice? Are these the ONLY pairs of numbers that can make up a twelve, for instance, if we weren't using dice and could use any number pair? Which larger number has more pair options when using a pair of dice?, etc.)
Page 3 (blackline): Dots on dice are removed. Students can experiment and fill in dots as dice are rolled.
Page 4 (blackline): Some students may not need help with possible dice pair options for each larger number. This is the page to use for them.
I hope you (and your students) enjoy!
