As I am cleaning/reorganizing my office, I wanted to share one of my shelves. The black abacus near the front of the second picture was a gift, but all of the rest were made for me by students.

Today for #BlackHistoryMonth, you should learn about Benjamin Banneker. He had very little formal education, but had a strong interest in mathematics and built America's first clock. It was a wooden device that struck every hour. #math en.wikipedia.org/wiki/Benjamin_…

We discussed nets and polyhedra in my education class today, so this is their homework. Create a dodecahedron full of different nets and their properties.

Finally, I look at finding the area of a triangle, knowing SAS using @geogebra. I also want to make a video of this one and discuss why this works! #math #iteachmath #mtbos geogebra.org/m/qavdkk38

For a different way to calculate area of a triangle, here is Heron's formula using @geogebra. I want to make a video explaining why this works soon! #math #iteachmath #mtbos geogebra.org/m/djpswb2w

Next up is an exploration on the area of general triangles using @geogebra. For this one, we use the formula for the area of the right triangle. #math #iteachmath #mtbos geogebra.org/m/u3x46gee

I always show memes in my classes. This is the one that always gets a super positive reaction from students. It is always their favorite.

This is my go-to math kit for the fall semester. I will bring it to every class so I always have appropriate materials and we can create the math as we go! Any suggestions for things to add? #mtbos #iteachmath
