Qr Code Activity
F.BF.3 Identify the effect on the graph of replacing f(x), by f(x) +k, k f(x), f(kx), and f(x+k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.
This is an activity for linear transformations. Students are given 26 QR Codes. Students use their MacBooks and QR Journal to scan the Codes.
Students fill in the answers on the sheet. Some QR codes repeat and some QR codes have text that is already on the fill-in-the-blank answer sheet. These "distractions" allow for the use of all 26 letters in the alphabet. As students proceed through the activity, they know that there are a set amount of QR Codes to investigate. The QR codes that have text already on the answer sheet actually help the students understand the task in context. Please realize that an answer sheet that contains blanks only would be too distracting for students. Choose a set number of QR codes so that your students are aware of their progress during the activity. If students don't know how many possible QR codes are in circulation, they may question if they are unfinished or finished with the activity.
Students also fill in the short blanks in the left margin that go with the corresponding QR Code capital letters in the lower right hand corners. Some student may know this review material and fill in the correct answers, but are encouraged to actually compete the QR scans in order to "Match" the QR codes AND the capital letters in the lower right hand corners.
