My homeschool co-op classes had a lot of fun creating this April calendar to hand out at our end-of-semester party on Friday. It’s not as easy to read as a traditional calendar — it is more like a puzzle. The expression in each square simplifies to that day’s date, so families can treat each day like a mini-review quiz: “Do you remember how to calculate this?”

Oh my gosh, I don’t know why, but this tickled me! A lot of my students’ parents are highly educated, so I think I may pass out this calendar (with your URL at the bottom, of course, so they can visit you themselves) as a little April Fool’s gag. I teach two- and three-year olds, so to tell their parents that we’ll be working on those skills for the next month would be fun.
I love your blog, by the way. I don’t comment much but I follow because I like math. Thanks for all you do.
That’s so fun! What a great idea.
Thanks for the reminder, Patti! The pdf file now includes a copyright notice at the bottom with a link to my blog. Of course, you are welcome to copy out as many as you want for family, classroom, math club, or whatever personal or educational use.
Hey guys,
Thanx heaps for your blogs. I have been using it as well. I find them very useful. By the way I am from Sydney Australia.
This is great! Thank you so much for sharing it. I am going to hang it and have the picklets do one each day as a “challenge”.

I also liked this the moment I saw it. Another way to use it would be to get the kids to produce a blank calendar and a seperate list of the questions in jumbled form and then get their class mates to insert them on the calendar in their correct positions!
Hi,
I hope you do the calendars every month. The April one was sent to me which is how I found out about this website and we love it.
Thanks,
