Activity Instructions

Have a student toss a bean bag onto the mat. Look at the numerator of the fraction that the beanbag lands on and have that many students stand on the unit fraction, matching the denominator. For example: If the bean bag lands on 3/8 have three students stand on 1/8 to show that 3/8 is made up of 3-1/8ths. You can say, “Each of you is one eighth, so you equal 3/8ths.”
