We have two classic puzzles for your April 1st class starters.
CCSS: MP.1, MP3,4.OA, 5.G, 8.EE, 8.SP
For members we have solutions.
Or you might baffle and amaze your students with our Ghost Whisperer lesson. They will think you are pulling one over on them until they figure out the math!
Another great April Fool’s day activity would be Robert Kaplinsky’s Foil Prank.
