### Who Will Get There First? Using the Rate Time and Distance Formula

This has been my favorite lesson of the year so far. I gave it to my Intro to Algebra Students during the Solving Equations unit. It just uses the simple rate*time=distance formula. The students have a lot of choices for the project. It took them 2-3 class days. The most important part of the project was explaining what the variable represented. You can see from the student examples below that they did not all do it correctly. However, overall I really was pleased with the engagement level and the end product. (See student examples below) I have given the directions to the project below as well.
Positives: Student Choice, Engagement Level, Problem Solving Skills, Messy Numbers, Differentiated learning, Real World problem, Outrageous,

To Work On: Find a way to access at the halfway point of the project. Some students don't get on track early enough.

Who Will Get There First?
You get to chose a destination.  You and a friend are going to race to a destination.  Your friend gets the faster transportation choice.   You get a 6 day head start.  Do all the calculations and see who will get there first.

Here are your modes of transportation choices.

Bike:  3.5 miles per hour average*
Scooter:  1.1 miles per hour average*
Skateboard:  1.3 miles per hour average*
Walk:  .9 miles per hour average*
Pogo Stick:  .5 miles per hour average*
Big Big Wheel:  2 miles per hour average*
Roller Blades:  2.5 miles per hour average*
Run:  1.8 miles per hour average*
*All average speeds are accounting for sleep and eating.

You may pick your own mode of transportation, but you must get it approved first.  It may not be motorized.

Destination Restrictions:  Between 500-1000 miles away from here.  Pick a city.

Equation 1:  You must have a variable in your equation to figure out how much time it will take you to get to your destination.

Equation 2:  You must have a variable in your equation to figure out how much time it will take your friend to get to your destination.

Conclusion:  You must justify who arrived first and by how much time.  Your answer MUST BE GIVEN IN DAYS and HOURS, not just hours.

You must give your results in a video link or digital document link with all information given.

Rubric
Chosen City with mileage by 10 minutes in.  5 points
Equation 1.  5 points
Equation 2.  5 points
Conclusion:   5 points

### DOC and the Magic Straw: A Story about the Benefits of Collaboration

This is a very short story about DOC who is the inventor of a magic straw.  The story carries symbolism to show how easy it is to share your work with others and also have them contribute with you.

SYMBOLISM

DOC is named after GOOGLE Doc

MAGIC STRAW:  The link that is created when you share a Google Document in VIEW mode.

MAGIC PEN:  The link that is created when you share a Google Document in EDIT mode.

I use Google Docs almost every day.  I love the ease of use.  If you haven't used a Google Doc, please take the time to try it out.  Most of all I love Google Docs because you never have to click on SAVE again.  So give it a try, and create a Google Doc and then SHARE your document for all to see.  Directions on how to share are below.
