Introducing one-step and two-step linear equations with bar models (Part 1)

(Part 2)

I know the acceptable term is "bar models" but I've always called them equation strips. I have a bunch of resources for teachers in this blog post I made if anyone is interested: #mathchat #mtbos #iTeachMath

I love relating the idea of solving equations to this representation! Students solve problems like this in early elementary school using part-part-whole models. This could help student relate this new idea to something that they already know.

Bar models are amazing. Every one of my 7th graders could intuitively solve 2-step equations using bar models... naturally using algebra moves.

@GlobalMathDept Nice work Howie!!

Keep posting here. I like your explanation.

Definitely showing this to my 7yo kiddo, thank you.

Don’t get it?

I really like this! How would you draw it if you had subtraction or negative numbers?

Loved hearing your talk at CAMT!!!
