Math Magic Trick

This discussion is part of a collection:CCSS Practice Standard 8

This trick gives students good number skills practice as they make up their own grids. Then they can take them home and impress their families. A good way to make the home connection. You can differentiate by varying the kinds of numbers used to make the grid, depending on the levels of students.

Do others have suggestions for math activities that children can engage their families with?

Hi cmead. I've used this scheme for students learning integer arithmetic. You can even plan to have the 'mystic' sum be zero. Here's a sample.
