  1. Dilation Task Cards with and without QR codes

  2. Dilation Task Cards with and without QR codes • There are ten cards. Topics covered: • Identifying translations, rotations, reflections, and dilations • Graphing dilations in the coordinate plane • Finding scale factor and coordinates from given information • Proving triangle similarity • I usually print the task cards on card stock and put each in a plastic sleeve so I can reuse each year. This also makes it less likely that students will write on the cards. • There are two sets of cards included: With QR codes (with answers) and without QR codes. • I prefer to use the QR codes. This allows students to self-assess by using a QR code reading app on their smartphone. There are many free QR code reader apps available. • Suggested uses: • Make a single set and hang them around the room. Students move from station to station. • Make a set for each student. • I prefer to divide my class into 6 groups of 4 and make one set for each group. All diagrams created using geogebra QR codes generated via http://goqr.me/
