This site offers a vast array of resources and information for working with Fibonacci Numbers, Golden Section Numbers, and the Golden String. Although the site design is "plain vanilla," the content is quite good. Be sure to check out the quick introduction page mentioned at the beginning of the site to find information on Fibonacci in nature along with images and activities. Links to activities are clearly marked with a pencil icon for quick access. Also included is an in-depth biography of Leonardo of Pisa who became known as Fibonacci in his later years. Students will love some of the number tricks found on the site under the Mathematical Magic of Fibonacci Numbers.

tag(s): puzzles (203)

#### In the Classroom

Share the site on your interactive whiteboard or projector; then allow students to explore the site on their own or in small groups. Provide the site as a resource to students when studying famous Mathematicians. Present the first portion of the Mathematical Magic to students and challenge them to find out why it works. Provide this link on your class website for additional practice outside of the classroom. Invite students to create highly visual Fibonacci online posters using Canva, reviewed here.

This site offers an in-depth look at statistics starting with looking at numbers then discussing ways to "lie and cheat using statistics." Range, median, mode, and standard deviation are explained with examples then methods of collecting data are discussed. The third page takes a look at ways that data is presented and what it really does or does not tell us. Although this site is rather "plain vanilla" as many math sites are, it does offer a lot of useful information on a topic that is sometimes hard to find.

tag(s): data (161), statistics (127)

#### In the Classroom

This site would be perfect to use on your interactive whiteboard or projector as an introduction to statistics. After viewing and discussing this in class, have students bring in examples found in the newspaper, Internet, or on TV to analyze. High school social studies or government classes can look at this statistical information as they follow and debunk political claims during election cycles. Have cooperative learning groups create short presentations on video demonstration what they found. Share this videos using a site such as SchoolTube (reviewed here).

The goal of the Lemonade Stands activity is to maximize profits over 30 days. You choose the price per cup, lemons per pitcher, sugar per pitcher, and ice per cup. Since the weather is random, you must be careful in deciding how many paper cups, lemons, sugar, and ice cubes to buy. After making your choices, set the game into motion to see the results. Feedback is given at the end of each sales day to help make adjustments throughout the month. The site requires JAVA.

tag(s): money (185)

#### In the Classroom

Create a link at classroom computers or the computer lab to use as a center during an economics unit. Chart students' results and have a contest to see who can obtain the highest profits at the end of 30 days.

This site is part of the Mathtrain.com Project and was created to host student-created math video lessons all in one place. It was created by Mr. Marcos and his students at Lincoln Middle School in Santa Monica, CA. Videos are searchable by topic or by most viewed, most recent, or most discussed. The site is highly interactive and has an option to subscribe to their free podcast through ITunes. In addition to the student-created videos, there are also teacher-created videos with explanations on different math topics. Most videos are under 2 minutes in length making them perfect to use for introduction or review with different math topics. This site runs in conjunction with mathtrain.com.

tag(s): equations (151), podcasts (57)

#### In the Classroom

Choose a student-created video to use as an introduction for a new math topic. For example, when working with multi-step equations, show one of the student's videos on the site on your interactive whiteboard as an example of how one student solved the problem. Use this as a springboard to classroom discussions on problem solving equations. There are several videos on the site with this topic, so a new video can be shown each day as examples of different problem solving methods. Use the student examples in your classroom to demonstrate how students can explain different math topics, then create your own explanatory video or audio presentations. Have students create podcasts using a site such as PodOmatic (reviewed here). Or challenge students to create a video and share using a site such as SchoolTube (reviewed here). Post student work to your classroom website or blog for students to use at home for review.
