Function Carnival is a wonderful challenge to draw graphs to represent what is happening in animated videos. View the very short video then draw a graph representing the action in the video. Watch the video that results from your graph to compare how well you represented the action. Use controls to adjust your graph. Seeing immediate feedback shows if the graph represents the correct motion, and if not, your video shows your inaccuracies. You can continue making adjustments to the graph until both videos match. Begin by creating a class and choosing a basic, advanced, or custom "carnival. " Share student instructions including URL and class code to begin. Be sure to view tips and information about the site to make the most of all features.

tag(s): charts and graphs (195), functions (70), modeling (9), motion (59), STEM (134)

In the Classroom

Function Carnival is perfect for teaching modeling and observation for math or science BYOD classrooms. Share directions on your interactive whiteboard or projector and allow students to work on graphs at their individual pace. Features built into this site allow students to see areas that need adjustment in their graphs. Be sure to include this site on your class web page for students to access both in and outside of class for practice. Have students take a picture of each graph and the result, then create annotated images including text boxes and related links using a tool such as Thinglink, reviewed here. Their explanations can describe why the slope of the graph changes, for example, when a parachute opens on the falling object.

Put math (and related science) fears behind you with podcasts with text transcripts from The Math Dude. The Math Dude makes complex math problems easy to decipher with his easy to follow explanations and tips. Listen to podcasts while viewing text explaining common math questions from basic algebra through SAT prep questions. Be sure to check out the "The Math Dude's Most Popular Tips" and "The Math Dude's Archives." Download podcasts as MP3 files and play through iTunes, QuickTime Player, and RealPlayer installed on a local computer. You can also simply play them from the site. Just be sure you click on the podcast play button and not one of the annoying videos or other ads! This site is loaded with advertisements. However, there is some great material underneath them all. NOTE: This site includes tools for blog users to interact with others. Any visitor can comment on the posts and podcasts or participate in Forums. There are also links to other tip blogs on the web page. Check your school policies on students posting comments, etc. to the web and whether they are permitted to do so anonymously and/or with name or initials.

Check ahead of time to be sure this site is not blocked at school. If it is blocked, consider subscribing to the blog via iTunes to avoid all the ads. External speakers connected to the computer will help broadcast the sound throughout your classroom. Help students follow along by opening the podcast article (transcript) ad-free using the Readability add-on reviewed here for your web browser. Project the ad-free article as you play the podcast. Share the link on your class web page or select specific episodes links to offer support for concepts you are studying, such as absolute value or sine/cosine. Extend the concept of The Math Dude by having students write and produce their own math tip podcasts or English tip podcasts to explain the grammar demons that haunt their writing.

Select a Subject (specific math topic) to view explanations and activities such as multiplying decimals or finding the mean. Choose Videos to explore over 1500 tutorials. Be sure to check out the worksheet area offering more than just print-and-use worksheets. Offerings include worksheet generators to produce and create your own problems. The free homework help forum is very useful for students and parents alike. The site also includes an excellent overview and explanations (via video) about Common Core.

Use a tool such as KeepVid reviewed here to download the videos from YouTube.

Discover and explore what is considered to be one of the best math channels on YouTube. Patrick's channel is all about sharing math ideas and content to make math easier and more understandable to all. Browse through videos sorted in the order uploaded or by popularity. Use the search to find specific content. Most videos run 10 minutes or less, making content easy to use as a supplement to existing lessons or for extra help. The videos are not done "Hollywood" style, but they do explain things well. If your district blocks YouTube, they may not be viewable. You could always view the videos at home and bring them to class "on a stick" to share. Use a tool such as KeepVid reviewed here to download the videos from YouTube. To remove all of the "clutter" and advertisements from YouTube try Quietube reviewed here.

tag(s): equations (155), functions (70), integers (41), number lines (22), polynomials (32), probability (130), problem solving (272), quadratics (32), square roots (24), variables (22), vectors (25)

In the Classroom

Share these videos on your interactive whiteboard or projector. FLIP your classroom and have students view the videos at home and discuss the content the next day in class. (This is a great option if YouTube is blocked in your school.) Use the videos to introduce math content or review any topic. Be sure to provide this link on your class website for students (and their families) to access at home for additional math practice or help. Sometimes seeing a slightly different explanation helps understanding.
