Students will practice determining whether a relationship between variables given in a graph or table is proportional or non-proportional with this set of 20 task cards. Students will also practice identifying the constant of proportionality, *k*, and writing equations given a proportional relationship. There are 10 tables and 10 graphs included in this task card activity. Two problems require computations with complex fractions.

A recording worksheet is included for students to show work and record answers. They can check their answers by scanning the QR code on each card. Connection to the internet is not required to scan the code. However, a QR scanner app is required on the device. There are several free apps available to download.

If you haven’t used QR codes in your classroom yet, I highly recommend them! Students love using the technology, and the self-checking makes it easier on the teacher!

A version without QR codes is included as well.
