Math 24 Activity
Object of the game: Make the number 24 from the four numbers shown. You can add, subtract, multiply and divide. Use all four numbers on the card, but use each number only once. You do not have to use all four operations. All number nines have a red center, so you can tell a nine from a six. Can you solve the card below?

Vertical Angles: Two nonadjacent angles formed by intersecting lines or segments. Also called opposite angles.
Complementary Angle: Two angles whose sum
is 90 degrees. A + B = 90⁰
Supplementary Angle: Two angles whose sum is 180 degrees. A + B = 180⁰

6. Vocabulary
Regular Polygon: A polygon with all sides equal (equilateral) and all angles equal (equiangular).
Irregular Polygon: A polygon with sides not equal and/or angles not equal.
Circumference: The distance around a circle.
Pi: The relationship of the circle’s circumference to its diameter, when used in calculations, pi is typically approximated as 3.14; the relationship between the circumference (C) and diameter (d),
