CINDY JOHNSON @johnsonmath AKA The Conic Card Lady
2
WHERE I WAS… I was teaching mostly low level Algebra 2 students who didn’t plan to go to college. Conics seemed impossible! Formulas were SO complex! I struggled keeping everything straight in my mind. How are they ever going to get it? In previous years my students did ok when the conics were separated but when they were supposed to identify the conic then solve, chaos began. Students HATED conics!
3
WHAT I STARTED WITH… Index Cards and Markers! What if I told them the answers? What if I never gave them the formula? What if we started with all the conics being mixed together and sorted them into the 4 types from the beginning? What if I made the assignments very straight forward where they reinforced what was being discussed, but didn’t overwhelm them at all?
4
CONIC CARDS Each deck of Conic Cards includes 4 types of cards - Graphs (5 each of the 4 conics) - Equations (5 each of the 4 conics) - Information (5 each of the 4 conics) - Formula/title cards Each deck has a unique answer key.
5
WHAT STUDENTS DO? Ultimately, they match all 20 equation cards to the correct information cards and graphs. Strategies I use… Small group activity Identify similarities and differences Make a conjecture. Quick mini-lessons to individual groups (1-2 minutes) Whole class discussions
