Exploding Dots

3.1 Welcome

Lesson materials located below the video overview.

Society loves working in base ten. So let’s stay with a \(1 \leftarrow 10\) machine for a while and make good sense of all the arithmetic we typically learn in school.

We have just seen how to write numbers. Next students usually learn how to add them.

Let’s start by exploring addition, and then go on from there. Woohoo!
