## 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

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

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

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.

When you don’t speak the same language, but you still all have to explain to the Mister:
