Find math advice, tips, ideas, games, and e-books to help bring math alive. Activities focus on two age groups, 3 - 5 and 5 - 7. The free e-books have math themes. The site's origin is British, so the "maths" curriculum or terms may be slightly different from the U.S. But numbers are still numbers! The standards are from the U.K. Although the site has links to items for sale, there is enough free material to be worthwhile.

Confused about climate change and the evaluation of the data? View this free site from the EPA that compiles current greenhouse gas emissions data into an interactive map. This site visualizes the biggest emitters. Included are polluters of more than 25,000 metric tons of carbon dioxide a year. Unfortunately, not shown in the data are the smaller polluters. When using the site, keep in mind that polluters like transportation, residential, or agricultural sources are missing. This tool is useful for looking at how industry and power contribute to climate change, and which type of fuel source (coal provides 50%) provides power generation. Click on the US map and then specific blue circles (the numbers inside represent the total number of facilities) to zoom in and find the list of facilities in the left navigation panel. Clicking on each facility brings up the data of emissions. Search by specific gas emission (carbon dioxide, nitrous oxide, or methane). Change the overall view by list, map, or graph to customize how best students view the data.
