CREATE GRAPHS AND CHARTS ONLINE
Infogr.am is a free online tool for creating four basic types of charts: bar, pie, line and matrix. Each chart type can be edited to use any spreadsheet information that you want to upload to your Infogr.am account. The information in that spreadsheet will be displayed in your customized chart. When you place your cursor over your completed chart, the spreadsheet information appears in a small pop-up window. Your Infogr.am charts can be embedded into your blog, website or wiki. To use the online tool, you must have a Twitter or Facebook account to sign into Infogr.am. Soon you’ll be able to create interactive infographic posters on Infogr.am.
MATH LIVE
Math Live presents students with animated stories that teach mathematics lessons. In all, there are 23 lessons for elementary school and middle school students. The lessons are divided into four categories: Number, Patterns and Relations, Shape and Space, Statistics and Probability. Each animated lesson is accompanied by a mathematics worksheet that students complete either while watching the lesson or after viewing the lesson. Each lesson is divided into sections, and students can advance or rewind as needed. An interactive glossary explains math terminology and concepts using text, images and animations.

YUMMY MATH
The Yummy Math website presents mathematics problems and scenarios based on things happening in the world today. For example, an activity for January 26 has students study historical Super Bowl data to reflect on average (mean, median and mode) losing scores, winning scores and range of scores. They are asked to judge which of these central measurements seems the most meaningful and explain their reasoning. Another activity has students plot the cost of a 30-second Super Bowl ad over the past 45 Super Bowls. How has the cost of a Super Bowl ad changed over time? Has it grown linearly? exponentially? Yummy Math lists activities chronologically as well as by mathematics subject area.
