Solving Systems by Substitution Resources

I asked the #mtbos if anyone had resources for solving systems by substitution that is not a worksheet. I have some nicely scaffolded worksheets to introduce substitution and elimination in this unit so I don't want to worksheet them to death for practice. And maybe they won't need any more practice but every year is different.

I had a lot of great responses so I thought it was worth sharing here.

Each pair solves and becomes an "expert" on a system that's printed on a slip of paper. Then one half of the class rotates by 1 seat, and the new pairs exchange problems and solve/check each other's work.

You could do an Add ‘em up where they find the intersection point but only add up one of the values. I found one online, but I’m not sure who it came from

is a fun website of emoji puzzles, the medium difficulty level is perfect for practicing substitution method. Students get really into it, and you can have them create their own, and try and solve them.

I make cut out pizzas, topping, and pizza order forms. Students have to work in a group to solve the system and figure how many if each topping goes on the pizza and deliver it. They get fake tip money for their fast and correct service.

There’s also a clue game out there that someone made a while back where students had to solve a system in a scenario to find the murderer, the weapon, and where the crime was committed. I’m not sure who created it though, but I used to use it when I taught algebra 1.

Unit Circle Art V

It's that time of year again for my unit circle projects!

My requirements are that it can't be made out of paper and has to contain radians, degrees, and ordered pairs.

See my previous posts here:  Unit Circle Art III, III, and IV.

We like to eat!!

And here is a link to the rubric. My goal with the project is to help them memorize the unit circle, notice patterns, and do a little work outside of class.


The Function Notation Trident

Three years ago I blogged about using the function notation slider and every year I tweet about it for #teach180. One year someone suggested I make the slider have a third prong for the answers too. At first, I was appalled that someone didn't love the slider as is and then randomly this year I decided it was a great idea and I should do it. Now. lol

And it was a great idea! I love how it turned out and it's my favorite use of the Boomerang.

Here's the file:


Written Response

This year I wanted to work on having students read and respond to somewhat academic articles.

My first attempt was posting the link to this article for my older students in Google classroom. I asked them to read it and then come back and type a comment about how they could relate to this article but not post it. Then, I counted to three and we all posted at the same time. Next they had to read everyone's comments and respond to at least one. I liked this idea because everyone's voice was 'heard' but nobody could be accused of copying since we all posted at the same time. And some students were surprised to see that almost everyone felt the same way.

I have to share some excerpts:

My second attempt was with this article. I posted a list of questions as a google doc and students had to write a short written response. Here is the link to a copy of the doc. As I was grading them, I pulled one quote from each person's paper. I posted all of the quotes, with names, as a google classroom post. I asked them to read all of the comments and then respond with either "I agree with ____ because ____" or "I disagree with ____ because ____". This did not go over nearly as well as my first attempt. I would recommend either the comments or the written response rather than this weird combination of the two, to be honest.

I do a semester paper twice a year so I considered this a baby version of that since it was less than a page. I'm mostly looking for their ability to follow directions, meet a deadline, and to put their thoughts into sentences. But I also wanted to do a little check to see if they actually read the article so I gave this 5 point pop quiz. Spoiler alert: they did not all read the article.

Next up are these two articles.
