Brief Description

Students use this math-based card trick to convince their friends that they can read minds!

Objectives

Students will
  • follow instructions to perform a trick.
  • critique fellow students efforts to help them perform to maximum level.
  • explain the math concepts behind the trick.
  • learn to use a video camera (optional).

Keywords

magic, math, card, trick, puzzle

Materials Needed[shopmaterials]

  • a deck of cards
  • a friend
  • pencil and paper

Lesson Plan

In this activity, students learn a cool card trick they can try on friends, siblings, and parents. Let them perfect the trick on their classmates first.

To incorporate technology into this activity, you might have students write their magician's spiel in script form, videotape one another, and critique the performances.

For detailed instructions for this activity, go to the Math Explorer Web site to find the The Mind Reader activity.

Assessment

Students will write a paragraph that explains in their own words the math behind this trick.
