## 5 Spook-tacular Ways to Bring the Halloween “Spirits” Into Your Classroom

Posted 10/06/2021 by Ellen Fishpaw (@ellenfishpaw)

Halloween is the first big holiday of the school year, and teachers would be ghoulish not to take advantage of students’ excitement and the Halloween spirit. Here are five of our favorite ways to tap into the Halloween spirits with Texas Instruments. No tricks, only treats!

1. Write creepy code on your calculator
Code your calculator to draw ghosts like in the image below. Have your students draw the ghost and pumpkin using transformations of functions. Here’s a snippet of code to get you started with a ghost:

• 0→Xmin: 0→Ymin: 264→Xmax: 164→Ymax: For(N,0,20,1): Pt-On(132-N,120-(1/10)N²,1,20): Pt-On(132+N,120-(1/10)N²,1,20): End
• For(N,0,10,0.5): Pt-On(132-N,120-(2/5)N²,1,20): Pt-On(132+N,120-(2/5)N²,1,20): End
• For(N,0,2,0.1): Pt-On(132-N,120-10N²,1,20): Pt-On(132+N,120-10N²,1,20): End

1. Explore exponential growth with zombies
Exponential growth and decay is often taught in the context of human populations, but what about zombie populations? This STEM Behind Hollywood activity explores the concept of exponential growth in the context of a zombie apocalypse. Trigger an outbreak of learning and infectious fun in your classroom — STEM Behind Hollywood: Zombie Apocalypse.

1. Dress up your TI-84 Plus CE or the TI-84 Plus CE Python graphing calculator
Gather some orange and black filament and 3D-print a spooky spare case for your TI-84 Plus CE graphing calculator. Here is the Pumpkin Pi edition of our Halloween-themed slide case that you can print from a link on Thingiverse: https://www.thingiverse.com/thing:3901650.

1. Create a calculator costume
In the teacher world, Halloween is the one day a year when math teachers can dress like a TI-84 Plus, and no other teachers can say anything else about it. All you need is some construction paper, scissors, tape and ribbon to transform from a teacher to a TI-84 Plus.

1. Haunted! Or hoax?
Put your students on a creepy case as they explore STEM and the ghost of Dead Man’s Curve. Ask students to analyze the science to decide if there’s even a ghost of a chance that a ghost is haunting the highway. Designed to complement middle school physical science and high school physics, the ghost of Dead Man’s Curve engages students in explorations of electromagnetism, the relationship of wavelength, and frequency and practical applications of electromagnetic principles with the TI‑Nspire™ CX or TI‑Nspire™ CX II graphing calculator.
