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!

Citizen Maths: A Free Course to Build Adult Math Skills

Do you want to improve your grasp of math so you can help your children understand their homework? Did math pass you by at school, or have your skills grown rusty over the years? Do you find it hard to apply what you know to the real-life problems you need to solve now—‌like using spreadsheets, interpreting data, or assessing risks?

If so, then the free, online, work-at-your-own-pace Citizen Maths course may be just what you need. Instead of abstract routines, the course uses practical problems to help you grasp some “powerful ideas” in math and see how these ideas apply in work and in life.

High school math teacher Chris Rime posted three wonderful review calendars for middle and high school students on his blog.

The links at Chris’s blog will let you download editable Word docx files. If you’re cautious about internet links and prefer PDF, here you go:

Chris writes:

There are no explicit instructions about process being more important than the answer on these, so you’ll need to stress that in class.

I remind students that everyone already knows the answer to each of the questions, and that one of the things we’re practicing is explaining our reasoning…

Enjoy!

And if anyone else has a math review calendar to share, for any grade level, please add your link in the comment section below.

Pi: Who Needs That Many Digits?

From Numberphile: Pi is famously calculated to trillions of digits – but Dr. James Grime says 39 is enough.

How you round it off makes a difference:

An extra note from Dr. Grime: “Since pi39 ends in 0, you may think we could use pi38 instead, which has even fewer digits. Unfortunately, the rounding errors of pi38 are ten times larger than the rounding errors of pi39 — more than a hydrogen atom. So that extra decimal place makes a difference, even if it’s 0.”

Pi and Buffon’s Matches

From Numberphile: Dr Tony Padilla’s unique (and low budget) twist on the Buffon’s Needle experiment to learn the true value of Pi.
