1. Teacher Guide
This lesson is designed to teach kids to ask a critical thinking question that you can’t just put into a search box to solve. To do that, we encourage them with smaller questions that search can help them answer. Make sure that you read the notes for each slide: they not only give you teaching tips but also provide answers and hints so you can help the kids if they are having trouble.
Remember, you can always send feedback to the Bing in the Classroom team at You can learn more about the program at bing.com/classroom and follow the daily lessons on our Partners In Learning site.
Want to extend today’s lesson? Consider using Skype in the Classroom to arrange for your class to chat with another class in today’s location. And if you are using Windows 8, you can also use the Bing apps to learn more about this location and topic; the Travel and News apps in particular make great teaching tools.

This lesson is designed to teach the Common Core State Standard: Mathematics
CCSS.MATH.CONTENT.HSF.LE.A Construct and compare linear, quadratic, and exponential models and solve problems.
CCSS.MATH.PRACTICE.MP4 Model with mathematics.
Alice -- this is what I found on-line, still not sure how to find the standards with BTCH. Tried Commend F
Linear, Quadratic and Exponential Models F-LE
Construct and compare linear, quadratic, and exponential models and solve problems
1. Distinguish between situations that can be modeled with linear functions and with exponential functions.
Prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals.
Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.
Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.

2. When can you use exponential, logistic, and linear growths as a model?

Having this up as kids come in is a great settle down activity. You can start class by asking them for thoughts about the picture or about ideas on how they could solve the question of the day.

All reasonable people know that the internet was invented so that we could share cat videos. Perhaps you’ve wondered if you’re missing out on some of the cute? Relax, the Bing team has you covered. In light of the exponential growth of web searches for videos of wee bitty kitties to melt your heart, we’ve made it much easier for you to get your daily fix.
Ladies and gentlemen, welcome to the Cute Cloud.
Finally, a search engine has harnessed the power of cloud computing and focused it in the service of all things cute. Only through Bing can you access the Cute Cloud, the virtual storage space for every cute picture and video on the web. Of course, as cute begets more cute, Bing’s Cute Cloud will continue to grow, shining rainbows of cute down on each and every one of us. Like seeing kittens play with empty boxes? Search the Cute Cloud and know that Bing has opened the window to all the web’s cute.
Depending on time, you can either have students read this silently to themselves, have one of them read out loud, or read it out loud yourself.

There are a couple of ways to use this slide, depending on how much technology you have in your classroom. You can have students find answers on their own, divide them into teams to have them do all the questions competitively, or have each team find the answer to a different question and then come back together. If you’re doing teams, it is often wise to assign them roles (one person typing, one person who is in charge of sharing back the answer, etc.)

You can adjust this based on how much time you want to give kids. If a group isn’t able to answer in 5 minutes, you can give them the opportunity to update at the end of class or extend time.

You can ask the students verbally or let one of them come up and insert the answer or show how they got it. This way, you also have a record that you can keep as a class and share with parents, others.

Exponential growth is a constant rate of growth applied to a continuously growing base over a period of time, it is geometric.

The exponential growth does not level off with a maximum value, where the logistic graph flattens off and looks like a stretched S.

Exponential growth and logistic growths are similar in the beginning and middle parts of their graphs, but as x increases the logistic curve becomes more horizontal and the exponential curve becomes more vertical.

Linear growth is arithmetic and exponential growth is geometric. When graphing in the beginning they can look the same but a linear graph keeps along the same rate of change, where the exponential graph will increase very fast leaving the distance between the two graphs to change quickly.
