![]() These fun online math games cover all of the math fundamentals, including early math, basic and mixed operations, fractions, pre-algebra, dollars & cents and place value. Mostly all of the material you'll find at the site is completely free for kids to use. This free section of Sheppard Software was written for children. It can be very difficult for parents to find productive and worthwhile activities for children on the Internet however fun online math games do offer a wonderful alternative. The games at Sheppard Software are well written, interactive and very fun to play. "Online math games, like the ones that you'll find for free at Sheppard Software, provide a valuable opportunity for children to learn a great deal while they're having fun. ![]() Fractions, place value, money, and basic operations are some of the areas that are covered. Students can shoot fruit, pop balloons, and even play math man (the math version of pac man!). The lessons include interactive activities to practice concepts.

In 1941, Milutin Milankovic linked ice ages to Earth’s orbital characteristics. In 1938, Guy Callendar connected carbon dioxide increases in Earth’s atmosphere to global warming. In 1896, a seminal paper by Swedish scientist Svante Arrhenius first predicted that changes in atmospheric carbon dioxide levels could substantially alter the surface temperature through the greenhouse effect. In the 1860s, physicist John Tyndall recognized Earth's natural greenhouse effect and suggested that slight changes in the atmospheric composition could bring about climatic variations. In 1856, Eunice Foote discovered that blanket, showing that carbon dioxide and water vapor in Earth's atmosphere trap escaping infrared (heat) radiation. He suggested something in the atmosphere must be acting like an insulating blanket. In 1824, Joseph Fourier calculated that an Earth-sized planet, at our distance from the Sun, ought to be much colder.
