This site is very kid friendly. It is called Hooda Math so that in itself is amusing for kids and the games are presented by icons so the students can just click and go.
This is great. It has so many games for math. it has math jeopardy and math millionaire. It also has the games broken down by what math lesson is being taught.
This site has tons of math games for many ages. It also has games for spelling, geography, science and more. I actually used this site in MAT141. It is really neat.
This site gives resources, strategies and activities for teachers to use in lesson plans. All you do is type in the subject and the site will give you options. Also it has recommended lessons. For example with black history month coming up it has special lessons to incorporate black history.
