Everyone loves word searches, right? But what if they were... brutal? Each of the 10 word searches in this download contain one ONE WORD, and that one word only appears once. Sounds easy, but the problem is that the grid is made up of only the letters IN THAT WORD! So you have to find "GRAMMAR" in a grid that only contains the letters G, R, A, and M! Kids love these! They make great bell work, or extra credit work, or just something to keep them occupied and quiet while other students are, s

Everybody loves a word search puzzle, right? This is a set of 10 of the hardest word search puzzles imaginable! The each only have one word to find, and that word only appears once!

Use these as "bell work" or "extra credit" or just something to keep kids busy and challenged while other kids are finishing up a test! Any time you need to keep students engaged and stimul

Here is a set of printable cards about “Exponential Functions” for use in a Precalculus or College Algebra class. I use these problems as part of teaching Chapter 3 Section in “Precalculus with Limits: A Graphing Approach” by Larson, but any Precalculus (College Algebra) textbook will have an equivalent section. Inventory of this download: Section_3.1_Group1.pdf: 56 cards (7 sheets) of problems that ask a student to determine a particular value of a simple exponential function. These problems ju

This activity uses the wild physics of the Breakthrough: Starshot initiative to teach about the Laws of Motion and the incredible challenges of interstellar travel. I have used this as a short lab, but usually this is just a classroom activity or a homework in my Astronomy class. If you aren't familiar with it, Breakthrough: Starshot proposes sending a very small (30 g) spacecraft to the nearest star system, using a solar sail for propulsion. How practical is this? How great is the accelerat
