• Hi! I was wondering how i enter full screen? The video without full screen, for me, is super small to where I can't see. There isn't a full screen button in the left or right bottom corner. Got any advice of how to either enter full screen or make the screen bigger?
• You should see a little square in the lower right of the video screen. Clicking on that square should take you to full screen.

• how to write number lines
• 1) Draw a long line on a piece of paper. This will be the base of your number line

2) Make hash marks on your line. This will make it look like a train track

3) On the left, start writing numbers above the hashmarks. Start with zero above the first hashmark on the left

4) Stop numbering at 20.
