One more new game to share before Halloween next week! This Ghost Game is an adaptation of a paper and pencil game that I found in a 1979 issue of GAMES Magazine. It is a variation of CrossCram. https://t.co/tRd3Uwl4fv #mtbos #iteachmath #teach180 pic.twitter.com/3V0Wwqq6VC

There aren't many opportunities in the Ontario math curriculum where you need 3D graphing but in the MCV4U curriculum when you have 3D vectors, using the new @Desmos 3D graphing calculator is the way to go. Here's some simple ways to represent vectors and vector operations,

Not only can you visualize vectors in Desmos 3D, but also perform vector operations in the expression list. Thanks for joining us as we have been #Unlocking3D🔒, and be sure to visit our Youtube page for all the videos! pic.twitter.com/kUxRtyNf95
