Work Out with Pi

Work Out with Pi is a Grade 7 circle-measurement game where playing cards generate a decimal radius. Red and black suits determine which digits fall on each side of the decimal point, then students calculate both circumference and area using 3.14 for π. Correct work lets the player collect the four cards used to build the radius.

Use it for partner or small-group review when students are applying both circle formulas and working with decimal dimensions. The card-built radii keep the problems varied while the paired calculations reinforce the difference between circumference and area.
