High school math teacher Chris Rime has done it again. Check out his November 2015 printable math calendars for Algebra 1 (in English or Spanish), Algebra 2, and Geometry students. Enjoy!
Things to Do with a Math Calendar
At home:
Post the calendar on your refrigerator. Use each math puzzle as a daily review “mini-quiz” for your children (or yourself).
In the classroom:
Post today’s calculation on the board as a warm-up puzzle. Encourage your students to make up “Today is…” puzzles of their own.
As a puzzle:
Cut the calendar squares apart and trim off the dates. Then challenge your students to arrange them in ascending (or descending) order.
Make up problems to fill a new calendar for next month.
And if you do, please share!

I love this idea! I have never seen anything like this before. I really like that if you do the problems with your students on a daily basis, then they already know the answer (since the answer is the date). This stresses the importance of the process of problem solving and wrestling with a problem and places less emphasis on just getting the right answer at the end. I will definitely be using something similar to this Math Calendar next semester during my student teaching!
That was always my math club kids’ favorite thing about math calendar problems. Even if I scrambled the days, they knew the answers would always be simple whole numbers — which let them relax and focus on thinking through the process.
