Activation
Everyone brushes their teeth on a daily basis. But do we all brush our teeth the same way?��Think quietly for a bit about how you brush your teeth and the steps you take. Be prepared to share your steps.
Did everyone have the same steps?
Did we all end at the same goal – clean teeth?
LESSON VIDEO
APPLICATION ACTIVITY
Using the coding map provided, create two algorithms for your bot to follow to get to the charging station.
You may want to move the “bot” along as you write the algorithm. Directions can be written at the bottom in the boxes or you may write in the boxes up top. When you have finished, have a partner try out your algorithms.
Are they both different and do you reach the goal in each?
CLOSURE
Take a walk around and look at some of your classmates maps. Look for similarities and differences. What do you notice?�
Did everyone have the same algorithm?
Was there a strategy that you used to complete the algorithm (shortest route, least amount of turns)?
Extension Activity
Materials Needed: Students can work in a group and each group will need a Sphero Indi Car.
If your school does not have a set of Sphero Indi Cars, you may borrow one through the St.Lawrence-Lewis School Library System’s Media Library Catalog at: https://sllboces.insigniails.com/Library/Home, or local lending library.
Sequence: Students would create multiple tracks that all end up next to the bathroom in their classroom. How many different ways can the Indi Car get to the bathroom?
