## The One with Individual Tangent Practice

### Image

I’m a bit more into individual practice, these days. A few years ago, I think I was more “all groupwork, all the time”, but I’m appreciating the fact that a decent culture of groupwork at our school helps support our kiddos when they’re working individually while also allowing them to spend time on what they need.

We’re still working through how reference angles are related to tangent ratios (without really calling them that – most kiddos are sticking with opposite and adjacent sides). Also trying to balance procedural work (especially with ratios) and conceptual thinking. Someone made a decision with this curriculum to round some of the tangent ratios to numbers that made it easier to solve for unknown numbers. While this may take away from the actual ratios (which are a calculator button push away, anyway), it did give a lot of kiddos access who weren’t familiar with solving ratios. Lots of struggle today and I’m hoping kiddos got something out of it.What do you notice? What do you wonder?

## Similar or Same: The One with Academic Language

### Image

That sinking moment when it becomes clear you didn’t teach vocabulary as much as you should have. There were some things that went well with this unit and a whole lot of new ideas for the next time we teach it, but I wish I’d done a better job emphasizing academic language, especially when the kiddos mistake “similar” for “same”, which is…reasonable, but problematic.

## Measure the Height: The One with Rubric Revisions

Some test revisions and explanations based, somewhat, on review day and a rubric.

## Which Triangles are Similar?: The One with the Similarity Group Test

### Image

Similarity group test to prepare for Friday’s individual test. Relatively solid in most of the classes

## Transamerica Pyramid: The One with the Scribblings

### Image

I’m a sucker for anything that involves kiddos labeling diagrams. Using diagrams of similar shapes to find missing sides. Especially proud that some of the kiddos circled the numbers (a strategy we learn in our 3 Reads protocols)

## How High?: The One Where We Estimate the Height of the School

### Image

First in a series of approximating the height of the school. Note the change in finding the second of the similar triangles.

Bonus points if you leave a guess for the height of our school in the comments.

## The One with Many Dilations

### Image

It’s fascinating to see how the kiddos think of dilating shapes. One of my big takeaways from this unit (slash, this year?) is that our lessons feel stronger when there are many ways to do the problem and we let students do the thinking. Obvious? Maybe.
