April showers have ushered in May flowers — and a second Math Calendar, with daily puzzles from my homeschool co-op students. Get your copy here:
How to Use the 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, then challenge your students to arrange them in ascending (or descending) order.
Make up problems for the next calendar!

Well, I probably won’t have another calendar until fall, when I put some new students to work on creating problems. But you could try Theoni Pappas’s 2009 math calendar.
