# Mental Math (Printable Puzzles)

Mental math. It causes so many students anxiety, but it’s a critical skill to be able to do more complex math. I’ve seen ideas similar to this, but they seem to use more prep (like writing things on craft sticks), so I’ve made my own. If you want each student to complete this puzzle, I recommend giving this page to each student, having them cut out the strips and glue them on a piece of paper in the right order. If you only want one set for your classroom, be sure to print it on card stock and then laminate the strips so they last longer!

# What’s My Equation? Array Math Puzzles

Here’s a simple idea that one reader submitted. Cut out a bunch of paper fall leaves (or any seasonal shape, like snowflakes for winter, hearts for Valentine’s Day, etc.) and laminate them. Then attach a magnet to the back.

Then put an array up on your white board. Ask your students what equation is depicted. There will be more than one way to write the equation.

Then discuss the answers as a class. For younger grades, the answer could be “4+4+4 = 12″ or +3+3+3+3=12”, but for upper grades the answer could also include “4×3=12” or “3×4=12”.This would make a great warm up for math lessons.

# Fact Families Graphic Organizer

I saw this idea somewhere and fell in love with it! This little house is home to a “fact family.” You could use this for addition/subtraction or for multiplication/division. Â I’ve made a full page version and a half page version. Sometimes having to complete aÂ half sheet (rather than a full sheet) seems less intimidating to kids even if it’s got the same thing on it. I’ve included a page to use as an example of how to complete the graphic organizer.
