I think the color is unnecessary - it is either an entire entry or is separated from the rest of the text by some type of punctuation. so what you did seems good. Following that same reasoning, I would not keep the bold on Math Reasoning (as you did not keep the bold on Social Studies Connection).
The other thing I noticed was the dash before the first entry - STARTING THE UNIT. I believe that is just a stylized print line and would not consider that a dash.
It looks like you are considering the text at the bottom of the page a reference note. If you only keep the bold o the word Algebra within the text, it would follow the rules in Section of BF - and a TN is required stating that bold words have a reference at the end of the page.
I'm glad you find Ask An Expert to be a benefit! Thanks for posting.
