Hello Enriched students, sorry I couldn’t hang out with you today!
The substitute teacher has given you notes to fill in as you watch the video below.  He or she will check your notes when you are done watching they video.  They will look to see that all your notes are filled in, and they will check the last slide to make sure your problems are correct.
When the teacher “okays” your notes, you may then work on the homework, which is page 229: 3-37 odd (skip 25). ¬†Even if you’re using mental math, make sure to show your work like I did in the notes!
