When did you learn the "magic trick" to drawing a cube? I'm pretty sure it was one of my 5th grade teachers who taught me. I've shown students before if it happened to come up and they asked, but never any students younger than 4th grade. Apparently the new Common Core math standards say that 2nd grade students need to be able to draw a cube! The 2nd grade teachers asked if I could help with this and I was very happy to assist.

After about 5-10 minutes of the students trying on their own, I finally showed them the "magic trick". The most common source of confusion comes from which lines to connect and which to erase. I asked the students to match up one set of corners at a time (top left to top left, etc.) and connect with a straight line. When it's time to erase, the students have to erase the inside of only one square which looks like a "Y" then erase a horizontal and a vertical line, each from inside the resulting rhombuses. If you keep your cubes looking transparent, you don't have to worry about it. If there was enough time left, the students traced the lines that stayed with crayon and colored each "face" of the cube a different color.
