Sheppard Software offers one online stop for many learning games and activites in the content areas of Language Arts, Math, Science, and Social Studies.
Many of the activities are very brief and offer a great way to reinforce a concept. In addition to the games there are also quizzes over the topic areas of Chemistry, Health, History, Nutrition, and Seasons.
There are quite a few Geography activities/quizzes that can be found on the site by clicking on World Geography Games or US Geography Games at the top of the page. The games are all based upon the idea of locating a requested area/country/city on a map.
In the Science section of the site you will find activities on the topics of dinosaurs, seasons, life cycles, cells, endangered animals, and deep sea science. Several different life cycles can be re-enacted on the Sheppard Software site. The life cycles of the butterfly, frog, and bird are all accessible and operated by the user placing the stages of the life cycle in the correct order.
In the Math section of Sheppard Software there are activities on basic operations, mixed operations, fractions, place value, time, money, early childhood math, and pre-algebra.
Language Arts activities that are found through the site primarily pertain to various parts of speech and vocabulary (all the way up to SAT and GRE vocabulary prep).
Take a look at Sheppard Software and see what activities would be helpful to your students. With the "game-like" environment of some of the activities, some students may even find this site as a fun place to spend a little time this summer on a rainy day =)
