Carole's Gift to You

This month’s free book is Pattern Grid-unLocks By Carole Greenes and Tanner Wolfram. Engage students with puzzles where they use pattern clues to complete grids. Along the way they will develop critical thinking, spatial thinking, creativity, and persistence.

Enhance your students' algebraic reasoning talents with this free puzzle book by Carole Greenes and Tanner Wolfram: Alge-Grid: What's the a?

And...check out Make It Proper, 1 a special bonus book by Carole Greenes and Tanner Wolfram. To solve puzzles, students use spatial clues to complete grids as they practice rewriting improper fractions as proper fractions.

Carole's Creative Puzzles, Problems, and Tasks

December 25, 2021: A Prime - Time
Lots of fun little problems and facts!

Who is SMOOT? What is a SMOOT? Learn all about this here!

The CUDI Challenge! CAN YOU DO IT? Students use math talents and logical reasoning to complete a 3X3 grid. Then…ask students to create their own CUDI Puzzle, submit it, and we'll publish them in an online book.

Carole's Commentary

I spent a great many years teaching at Boston University. Near BU is the Harvard Bridge that connects Boston on the south with Cambridge in the north. On the Cambridge side is the Massachusetts Institute of Technology.

What is different about the bridge is the length of stripes on the road. On federal and state roads, stripes are 10 feet long. On the Harvard Bridge, that changed in 1958. What happened?

Check out the SMOOTS problem in Carole's Puzzles, Problems, and Tasks to find out!

Great Ideas from the MathLink’s Team

The new and improved 2nd edition of the MathLinks Core curriculum will be available in about a year for Grades 6, 7, and 8. Here is a sneak peak at one of the Activity Routines that will be built into the program.

Picture Talks


Welcome to Carole’s Corner!

CMAT is honored that Carole Greenes is joining our CMAT team as a distinguished contributor. I personally met Carole when she wrote and directed the 50th anniversary musical celebration for NCSM. Her energy and spirit are contagious, and now Carole is part of the CMAT family.

We are so excited that Carole will be sharing some of her engaging puzzles, projects, tasks, and wisdom with all of us through Carole’s Corner. Every month, Carole will share her thoughts of the moment in Carole’s Corner. We also will post some of Carole’s activities, puzzles, tasks, and projects, with connections to MathLinks materials. Carole would like these selected materials (and solutions) to be free to you, so download, enjoy yourself, and use with your students!


Thank you, Carole,
