Trigonometric Functions of the Special Angles of the Unit Circle Self Checking Magic Pixel Art with Google Sheets
In this NO PREP digital activity, your students will practice finding the exact trigonometric values 24 special angles. As they enter the correct choice into the purple column, a fun pixel art image is revealed almost magically, pixel by pixel. No coloring, no wasted class time. Students will know they have typed the correct answer if they see the colored pixels appearing! If nothing happens, then students know to self-correct their answer. Students do NOT need to be familiar with Google Sheets to do this activity.
Problems include all six trigonometric functions of special angles around the unit circle. The problems are in both radians and degrees. Students should not need a calculator. Since entering math symbols is difficult on the internet, I have created a table of the 20 exact values used in these problems. Student choose the correct value and enter its matching letter into the answers columns.
The downloadable pdf includes the link to this product, full illustrated directions on sharing and using this resource, a printable response sheet with room for students to show work, and a printable handout with 15 similar problems which can be used for HW, assessment, or enrichment. All answer keys are included.
