Take 10 cards from pack including the 10 Diamonds.

Lay out card in 3 columns in a pattern of 4 down, 2 down, 4 down.

Group students around. You turn your head away and ask a student to point to a card.

You carry on, think allowed and then ask your assistant to point to cards asking:

Is it this one?

No.

Is it this one?

Awesome Math Mural

May 28, 2018

This math mural is on a high school wall, somewhere. It works because it has a street art vibe. Not a grade school math book look. That’s cool. 

Why not do something like this for your school.

Trick 6: Freaky Math Medium

May 27, 2018

Write the word carrot inside your math text book. Do not show students.

When Mathspig was a mathspiglet we used to play this trick. It doesn’t work on everyone, but it works  often enough.

Ask a student to say 15 times 15 fifteen times.

Then ask them to name a vegetable. Students say carrot 90% (I’m guessing) of the time.

To make this trick more dramatic send 10 students out of the class before you begin and tell the other half what you are about to do. Students return one at a time. How often do they say ‘carrot’? What % of students say carrot?
