This game helps students master 3.MD.B.4 without even realizing they're learning.
The game board consists of a box with 21 lines. The students play with a partner and each partner uses a different colored pen or pencil. The students label each tick mark beginning with 0 and moving up in increments of 1/4. On their turn, each student can choose to write one number or two numbers. The student who gets to the end and writes "5" is the winner! See the pictures for an example of how to play.
After putting this game into centers, the students were all able to correctly label a ruler with 1/4 inch increments.
