Bullseye Math
The object of this math game is for students to use problem solving strategies and math reasoning skills to make bull’s eyes.
Materials:
Per Group of Students 1 Deck of Cards numbers 0 to 9 only 1 Die—6 sided
Procedures:
1. Place cards deck is face down after shuffling
2. One student rolls the die to determine the target range (see table)
3. Students take the top 4 cards from deck
4. They use the cards to use any function and combination of numbers to find an answer that fits within the target range.
5. If the student’s answer falls within the target range, then he/she hits a bull’s eye and wins.
6. Each player plays five times and the one with the most wins, wins the game.
Example:
Die = 2
Cards 4, 7, 5, 2
7 2 (4 x 5 ) = 980
Variations:
Multiplication Bull’s-eye
Division Bull’s-eye
Fraction Bull’s-eye
Decimal Bull’s-eye
Addition Bull’s-eye
Algebra Bull’s-eye
Bull’s Eye Table:
Number on Die Target Range
1 000 - 500
2 501 - 1500
3 1501 - 3000
4 3001 - 4500
5 4501 - 6000
6 6001 - Higher

Math Problem of the Week
Three people walk into a motel and ask for a room. The desk clerk says a room costs 60 dollars, so each person pays 20 dollars towards the cost.
Later, the clerk realizes he made a mistake, that the room should have only been 55 dollars.
He calls the bellboy over and asks him to refund the other 5 dollars to the 3 people.
The bellboy, not wanting to make a mess dividing the 5 dollars three ways, decides to lie about the price, refunding each person 1 dollar, keeping the other 2 dollars for himself.
Ultimately each person paid 19 dollars towards the room and the bellboy got 2 dollars, for a total of 59 dollars.
But the original charge was 60 dollars. Where did the other dollar go?
