## Assessing math vocabulary

Assessing math vocabulary is important because math is a language and if you don’t know the words, you will have difficulty speaking it. Here are a couple of good links on making vocabulary assessments.

Also remember that Math Spelling City gives math vocabulary tests online and lets the students print them out!

## All About Triangles

Videos are a great way to get students to think. Good ones keep students engaged and teach. Here is a great video about triangles by Grover and Rita. It’s funny, well-done and pushes on students’ narrow conceptions of geometric shapes. It is a great springboard into a discussion about attributes!

Grover and Rita present triangles.

Here is also a great song about triangles (more upper elementary).

## Teaching Number in the Middle

Strategy work is important. Here is a great approach when teaching double plus 2 facts. You can begin teaching these facts in first grade towards the end of the year, but really it is often a 2nd grade strategy. Some people call this *Monkey in the Middle*, while others just call them 2 apart facts. I like calling it *Monkey in the Middle* — it is kid friendly. The kids tend to remember it. See these links to get started:
