In the spirit of sharing more about how I use QR Codes in the classroom, I have posted a Freebie worksheet in my store.  This worksheet has problems that allow students to practice working with similar triangles.  This page is appropriate for a high school geometry course.

This worksheet has 8 problems and allows students to get the answer immediately by scanning the QR code with their smart device.

What is different about just checking the answer with the teacher or in the back of the book?? Nothing really, except using technology in class is fun :)

If you download this worksheet and give it a try, let me know how it works - I would certainly appreciate your feedback.



Have a great day!
