Before the holidays (16 activities)

We have tons (well, 16) of activities to bring to your class in this last week before the holiday break. Movies, science, art, cooking, economics, weather and the logic of calendars. Enjoy!

Whole lot of cookies

Jennifer Fairbanks from Hopkinton, MA sent us this picture of the cookies that she baked in 4 hours using 13 eggs and 5 cups of sugar. Do you see some math here?

Inflation and the cost of gasoline

In 1980, a gallon of gas costs $1.22.  Today’s prices are a lot higher.  Is that because the price has gone up or because in 1980 you could buy a lot more with $1.22 than you can buy today?

Mystical Mathematical Mind Reader

The GHOST WHISPERER now has a replacement!!!! John Tranter of Transum Mathematics has created the Mythical Mathematical Mind Reader and we’ve updated our activity to accompany the fun.

Bowl by the hour or the game?

Students consider the posted pricing of this bowling alley. What must they consider when choosing how to pay? What do you expect will be the best deal? How do you know?

Will one roll be enough?

Students can use the man or the basket as a reference as they try to approximate the size of these gifts and how much wrapping paper will actually be needed. Approximation, surface area, reasoning explanation, and diagraming! An X-box is…

Wrapping presents on the diagonal

In this activity students determine if this method for minimizing wrapping paper is actually more efficient then the traditional method. For a hands on learning experiment, have students actually wrap a small rectangular prism using any available paper in both the traditional and diagonal methods. Then let them compare the two quantities of wrapping paper and decide which method uses less paper and by what percent.

End of Daylight Savings time confusion

In this activity students try to figure out how time settings will change as they move from place to place and what variables are involved in the daylight savings time shift. Day length? Latitude?
