The cards have been designed to be used in a class of 10, 15, 20 or 25 students.
A symbol, at the bottom of the cards can be used to sort the cards.
• If you use cards with a heart, the set will make one cycle with 25 cards.
• If you use cards with a diamond, the set will make a cycle of 10 cards.
• If you use cards with a club, the set will make a cycle of 15 cards.
• If you use the cards with a spade, the set will make a cycle of 20 cards.
Using the symbols you can quickly sort the cards into a set of 10, 15, 20, or 25 cards.
Included in this activity are
• A teacher’s master list of all 28 cards. The “I Have” for card 1 is not the answer to card 1. It is the answer to either card 15* , 20* or 25. The “I Have” for card 2 is the answer to card 1.
• One set of 10 diamond cards, 15 club cards, 20 spade cards, or 25 heart cards with U-Substitution completed. (Green Border)
• One set of 10 diamond cards, 15 club cards, 20 spade cards, or 25 heart cards with U-Substitution completed and the integration completed. (Blue Border)
You need to use either the set of 10 diamond cards, 15 club cards, 20 spade cards or 25 heart cards to complete a cycle.
• In one lesson you might use the cards that have the students only complete the U-substitution. (Green Border)
• Another time you might use the cards where the students must complete the integration after they do the U-substitution. (Blue Border)
• The cards have been designed to give you some options for putting the lesson together.
• Distribute copies of the Student Recording Sheet for students to record their solutions to the problems that are read.
Distribute the cards. Have one student read their question for “Who Has.” The student might want to write this integral on the board for everyone to see. The rest of the students should set up problem and try to solve it. When someone discovers they have the answer to the question, they read their card. This produces a new card and a new problem. The new problem is described and the class works on a new problem. This procedure continues until the last person reads their problem and it turns out to be the answer of the original first card.
