This is a three page Word document containing 16 questions that require students to use the conversation heart candy as manipulatives. There are also 2 bonus questions. They include fractions, pictorial representations of fractions, all four operations, graphing, comparing, and money. I created it on a Word document so you could modify it to fit your needs. These questions were created for third grade, but could be modified to fit any grade level.
My students struggled with comparing fractions. I created a lesson around what my boys loved: wrestling. We gave each fraction a wrestler's name, and they wrestled. They loved it! After we taught the content, I then gave everyone a fraction to wear around their neck and they would "wrestle" (compare their fraction to someone else) to see who was the champion (greatest fraction) of the class!
