Weekend Warriors: Incredible Equations

Weekend Warriors: Part Two. What you didn't know? Yep, this is a two day affair.

In case you missed it- yesterday's post Counting Gloves was the debut of Weekend Warriors. Each month we are posting with TWO days of tips and tricks.... we can't use the word "Warrior" in our title for just one day... right?

Today I am sharing an idea that I shared once before on this blog back in February of 2013. So if you read it already I am sorry... but I am guessing this is new for most of you  all of you, but a small few.

Incredible Equations! This is something I use as a time filler or as part of my calendar- I've done this in both kindergarten and first grade.

The little ones tell me equations that match the number for the date. For example, on May 20th, the number we used was 20.


In the beginning you really have to model it A LOT, but they get the hang of it quickly.

I usually add this to the game in about January - but if I were to try it out between September and December I may just keep rotating through numbers 1-10 rather than adding the higher numbers, but now they impress me every single time with how well they can deal with the larger numbers!

Right now they are really into these types of equations: 20+100-100=20. One clever friend figured that thing out and now they all just think it is the best... and really, I think it is too!

I like this because ALL the kids can participate. I have some throwing out equations without any hesitations and others who can't create their own but after they hear "9+1=10" they can tell me "1+9=10." I mean, this is the commutative property of addition, isn't it?

And as you can guess, after seeing "15-5=10" one little friend may try "5-15=10" and this leads to a great conversation and pretty soon they get it. Some years subtraction doesn't show up on the scene for a while, but that is all dictated by what the class is ready for.

Sometimes we add the tally marks and/or the tens frames to help them build equations. Sometimes we fill the paper up and sometimes time only allows for a few equations. Really it is up to the kids what goes on here.

Oh, I do have one rule... and that is the good ol' "1+1+1+1+1+1 etc" can not be used on any numbers greater than 10, but on the 1-10 days it is almost always the first equation thrown out there.



Have you ever bought the packs of stickers (or punch outs) and you use the letters, but what do you use the numbers for? They just seem to accumulate over time...... well, that is why I use the stickers. Sometimes I just keep it simple too, though:

This is on a clip board on my calendar wall and each day I draw a name to take home the Incredible Equation from the day before. They love taking these home.

  1. O.M.G!!!! I thought yesterday's post was amazing, this one blew it out of the water!!! I remember doing incredible equations during student teaching, but I forgot all about it until now! And I LOVE the idea of choosing a kid to take the incredible equations home AND I love that you used stickers for the numbers!!! I'm kind of obsessed!!! Do you ever feel brave enough to give up control of the marker and have your kids come up and write the equation??

    1. Ahhh thanks! Glad you love it. You know back in the day when I had first grade I did let them write the equations... but I never have done that with K... maybe I should?!?

  2. this is such a fab idea - a simple but effective way to practice basic facts and the kiddo's get to learn from each other as well - thanks for sharing :)
