TITLE: The Math Detective

SUBJECT: General Math, 7th Grade

TOPIC: Converting fractions, decimals and percents

INTERACTIVITY: The students will be able to align pre-made cards on the bulletin board so each representation (fraction, decimal, or percent) is matched with their equivalent representation (decimal, percent or fraction) on all four sides.

DIRECTIONS FOR USE: The students will select cards out of the detective’s briefcase and align them on the bulletin board so each representation (fraction, decimal, or percent) is matched with their equivalent (decimal, percent or fraction) on all four sides. After they have aligned all 16 squares, the squares will spell out the answers to each question given on the worksheet. The student must also write the answers to six of the problems on the worksheet. Turn the worksheet in for extra credit.

TIME: It should take the students 10 to 20 minutes depending on the ability of the student. A calculator is allowed to shorten the time.

SPECIAL CONSTRUCTION: Each square is laminated and a magnet was hot glued to the back of each one. A magnet was also attached to the cloth where the squares will be placed. Each square is carefully made (calculated) so that each side of the square will match up with another side of another square. There also should be no repetition of numbers so the students are less confused.

CREDIT: The student will receive 5 extra credit points for completing the worksheet.

OTHER COMMENTS: In order to decrease the amount of time the students should be allowed to use their calculators. Also by having them answer six questions at the bottom of the worksheet (according to the squares) the teacher will know that they appropriately matched all of the squares instead of finding the answers to the questions from other students.
