Note from the author:
A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.
The outlined content above was added from outside of Formative.

Solve It! You want to download some new songs on your MP3 player. Each song will use about 4.3 MB of space. The amount of space available on your MP3 player is shown in the image. At most, how many songs can you download? Hint: 1 GB = 1000 MB

Enter only a whole number without a comma.

Use Your Vocabulary: A student uses the word compound in three different sentences. The sentences are listed in the right column. Tag sentences that correctly use the word with a √ symbol. Tag sentences that do not with a ⊗ symbol.
• In chemistry class we learned about various chemical compounds.
• Compound inequalities contain more than one inequality symbol.
• To simplify an expression, compound like terms.
