If you have ONE MORE DAY (or two or three), try out a few of these creative extension ideas"
BuildinG A BIG TETRAHEDRON
TIPS for constructing larger tetrahedrons:
Use packing tape: it works best for the long edges. The more tape…the better! Using cardstock paper also gives larger tetrahedrons more stability.
Reinforce connection points with straws or popsicle sticks: To prevent sagging, tape straws, rulers, or sticks along weak spots.
“Quality control” is important when taping and joining tetrahedrons...so is teamwork and cooperation.
Decide the size first: Tetrahedrons grow by four: 4, 16, 64, 256, 1024, 4096. Hint: A 64 piece one takes about one hour. A 16,384 piece one could take several months and requires a very large space (see photo).
Other fun ideas…
COOKING/MATH: Have a BBQ sauce tasting competition. Use potato chips or crackers to sample sauces. Compile, chart, or graph results.
ART: Create cartoon-style illustrations inspired by the artwork of James Harris III.
WRITING: Choose one of the seven characters and write one more chapter in their voice telling about their future life.
GROUP PROJECT: Develop and plan a world record attempt for your school.
Fill a bus with soup cans for a food pantry, or read a thousand books...
TECH/COMPUTER: Design a promotional website, video, menu, or Podcast
for Willy Q’s BBQ.
ART/TEAMWORK: Have each classroom choose a scene in the story and
“design a door” to recreate that scene. Give out prizes for the best doors!
More great tetrahedron extension activities can be found in this article in the
Mathematical Association of America magazine.
DISCUSSION: Describe a special food or family recipe that evokes a strong memory for you.
