K14 – Supply and Demand

How do live lessons work?

Live lessons are interactive slides and course outlines that are used to teach Treeway Live Classes. Click on the arrows to navigate backward and forwards through the slides.

How Do I Use the Lesson Plans?

Read this lesson plan before class to familiarize yourself with the ideas and concepts you’ll be teaching the students. You may print this page out if you need to use it as a reference point during live classes.

This lesson is a guide, but feel free to expand on the content or decrease/increase what you teach depending on the learning levels of the students in your class or the amount of time you have to cover the material.

Can I show videos in live classes?

Yes, feel free to include additional material to supplement the class lesson material. Videos, Physical Objects, Games, Activities, etc. are okay to share in live classes.

Videos should have no advertisements or logos and should be viewed by you before showing them to the students to ensure no offensive or questionable content is included.

The video should make up only a small portion of the live class.

How do bookmarks work?

Bookmarks help you keep track of lessons you’re going to teach in future live classes. The bookmarks you see are for all your bookmarked lessons across all grades.

You can bookmark a lesson by visiting the lesson you want to bookmark and clicking the “bookmark” button in the bookmark section.

You can remove a single bookmark by visiting a lesson you’ve bookmarked and clicking the “bookmark” button again to unbookmark it.

You can clear all of your bookmarks by clicking the “clear all bookmarks” button. Be careful, this will erase all of your bookmarks.

Lesson Slide

K13 – Consumers and Producers

Main Teaching Points

Supply is how much there is of a good or service.
Demand is how many people want to buy a good or service.
If the supply or amount of an item is low and the demand is high, there will not be enough for everyone.
When there’s not enough of something to go around, because not enough of it has been made, it is called scarcity.
We can’t always have everything we want, so we have to make choices based on availability. This is called economics.
