### PRODUCT DESCRIPTION

This lesson brings together a unit on extending the number line as it applies to real world contexts.

This lesson includes:
Lesson problem (room specific for notes, build it together!)
Practice Problems (designed for back of lesson problem)
2 Exit Tickets (leveled)
Station Activities (7 – Ideal for student presentation and peer teaching)
Solutions

While it’s not necessary, it’s helpful if students have already applied the concept of elevation to the number line. New vocabulary: depth.

Students here graph and analyze elevations on a number line and distinguish comparisons of absolute value from statements about order. In other words, the greater the depth, the lower the elevation and that elevation must be below zero.

I went right in to talk about mermaids. I usually refer to the Discovery Mockumentary “Mermaids: The Body Found” and it’s fun to watch a clip if you can. When it came to independent practice, there will naturally be the temptation to position all positive numbers above zero, just point out the word depth and refer to mermaids (or whatever your hook) and they’ll remind you what that means. [We also started the entire lesson with a quick review on where positive and negative numbers reside in relation to zero.]

This lesson incorporates the vertical number line. The stations are numbered so that they could be combined with the stations I’ve posted with the Balances and Debts lesson that incorporates the horizontal number line. Also suitable for a future review. It makes differentiation easy to assign more of some or the other.

I found it helpful to assign a station for homework with impending presentation. Even if the student had already solved the problem, they will reinforce the concept by reapplying what they’ve learned and teaching it as well. Just a thought! Happy teaching ☺
