Piecewise activities to get students buzzing

When it comes to students practicing their math skills, piecewise activities are a great way to reinforce their knowledge of functions, limited domains and transformations while making learning fun. And we’re willing to bet these math worksheets are the key to unlocking your students’ love of math.

Choose from a variety of piecewise activities, featuring a whimsical “Bee Mine” design alongside two other valentine-themed options. Each activity offers three distinct levels of complexity, inviting students to dive right into limited domains of piecewise functions, identify transformations, or sharpen their math skills by creating their own original design. The flexibility ensures you can tailor each activity to best suit your students’ abilities!
