WYR: Birthday Cake Edition Anchor Chart Example 1

Check student understanding of fractions with this quick check. This document (linked in the resources tab) is able to be printed for use of an anchor chart or used online. Color & black and white versions included.

Anticipated misconception: Students may believe that the fraction with the larger denominator will have the greater value.

Special consideration: Some students selected 1/9 with the understanding that it was a smaller amount, citing "While 1/3 is more, but I wouldn't be able to eat that much cake!"

Solidify and confirm that 1/3 is greater than 1/9 with a visual model.
