This set of cards can be used to review slope concepts. CCSS 8.EE.B6 and 8.F.A.3 are emphasized. This would be a great activity for students entering Algebra I. Each card has a problem written in black and a graph and an answer to another problem (in the blue box at the bottom right). By using the 10 cards that have a ♡ at the bottom you will have 10 cards in the scavenger hunt. If you use the 20 cards with a ♢ you will have a scavenger hunt with 20 cards. (When using the 20 cards, you will not use one card with a single heart. )
These standards do not emphasize the common slope formula so students are not encouraged to use
, but should calculate the rise and the run from the graphs.
Suggestions for working with the cards:
1. Post the cards around the classroom (either a set of 10 problems ♡ or 20 problems ♢).
2. Assign different students to start at different numbers. Distribute copies of the sheet with coordinate grids. Students should record the number of the card they are working on in the small square at the top left of the grid. When the work on the problem, they then go on a scavenger hunt to find the card with their answer in the bottom right corner of a new card. If they can’t find there answer they need to check their work again. When they find their answer on a card, they record that number in the next square and solve the new problem. Students keep working on problem for the allotted time.
3. The last two cards show the cycle for the 10 card and 20 card scavenger hunt.
4. The goal would be to complete as many questions as they can in the allotted amount of time.
5. Awards can be given for the number of problems completed by each student.
