Students create riddles using sufficient conditions.

Objective: Strengthen students' understanding of sufficient conditions.

Activity: Students create riddles using sufficient conditions. Each student draws from a cup the name of a shape written on a piece of paper (either a rectangle, a rhombus, or a square). The student then creates a riddle about the shape they have drawn using sufficient conditions (i.e., I am equal but not always right. What am I?). Each student reads their riddle to the class while the remaining students attempt to answer the riddle correctly. Students use a computer program to construct the special quadrilaterals by using the sufficient conditions. They complete a worksheet over the computer activity.

Assessment: Accuracy of the riddle and participation in the activity. Completion and accuracy of the computer worksheet.
