TAKING NOTES

1. Get out the connecting multiplying to division video.

2. Set up your Springnote journal to take column notes. Write two “guiding questions” at the top.

3. Go through your notes from earlier classes. Look for examples of long, complete sentences that you have written down. Now, read these sentences to your teacher. Watch how your teacher cuts out words you do not need.

Synthesis

The relationship between division and multiplication may seem like an easy concept to master…but can you figure out when to use which operation??

Answer the following questions and be sure to show your work. (Hint: There may be numbers you don’t need, OR there may be a few steps involved in finding the answer.)

1. If you buy a dozen eggs for $2.40, how much do you pay per egg?

2. If you stand on the corner and sell the eggs you bought in question #1 for $0.30 each, how much will you make in profit?
