### Dicey Fractions

What is it about rolling dice that kids love so much? I don’t know, but every dice roll activity I come up with my son loves. This dice roll was made to work on fractions, but incorporates so much more – counting, tallying, animals (i.e. mammals vs. non-mammals), and geometry (shape names, polygons, etc.)!

First we read Working with Fractions, a book by David A. Adler (who also wrote the wonderful book that taught my son all about roman numerals).

Then, I gave my son a fun die with six different colors, animals, and shapes. (I printed this on heavyweight cardstock, cut out, scored the lines with a straight edge and butter knife, folded, and glued the flaps.)

With a special recording sheet in hand and the timer on our microwave set for 2 minutes, my son was ready to get rolling!

He rolled the dice for the entire time, making a tally mark in the boxes under the square that showed up on top of the dice with each roll. I reminded him “One, two, three, four, and five shuts the door” to help him organize his tallies in groups of five.

When the time was up, my son counted the tally marks in each box and added all of the numbers together (I helped). The total was the denominator (the bottom number) on the fraction answers at the bottom of the recording sheet.

To complete the fractions, he had to figure out the numerators (the top number). Several of the fractions required that he add number of rolls from different squares together.

This was good practice to understand what the numbers on a fraction represent and reminded my son about what makes an animal a mammal, which shapes are polygons, and the reinforced geometry vocabulary too!
