Here's a draft of a sequence of 6 tasks. Included in the speaker notes are sample hints/prompts to support/challenge/extend thinking, sample teacher moves and assessment considerations.

In this sequence @MSBJacobs shows that you don't have to create lessons with a lot of moving parts to have students develop understanding. In this case, we are looking at algebraic expressions with a combination of virtual tiles and vertical surfaces. Check out the entire thread here:

I tried this activity in @MsLyon16 's MTH1W class using Polypad on @MathigonOrg to help illustrate algebraic expressions. First Q: if this is x + 2 what would 3(x+2) look like? Students go to the VNPS to work in small groups: pic.twitter.com/H4EOyLnLvF

Having just done a workshop at NCTM about visualizing multiplying and dividing fractions (https://bit.ly/nctm2022petro), I totally resonate with this post.

As a former physics teacher, I totally love the mix of @Desmos and other interactives on this sight. Check them all out. Even if you don't teach physics directly, you may find some that are perfect for your math class.

The first time I was introduced to the #DebateMath idea was at Twitter Math Camp in 2017 in Atlanta and it was a pretty cool idea. I think that having some of these debate cards makes doing this in your class that much easier.

It looks like @JRappaport27 has really been doing a good job of taking resources from all over the Twitterverse and consolidating them into solid lessons. Here's one set dealing with fractions:

Each task follows this sequence:
1. Which One Doesn't Belong
2. Build fractions using cuisenaire rods, adding constraints along the way.
3. Fraction Talk to consolidate, connect and extend.

Behold one of the mightiest tools in mathematics: the camel principle.

I am dead serious. Deep down, this tiny rule is the cog in many methods. Ones that you use every day.

Here is what it is, how it works, and why it is essential. pic.twitter.com/cevNDm2ASe
