I love the site, “Math Chimp!” It is a great collection of CCSS aligned games, videos, printables and lessons for math. It has been one of my go-to sites for math resources and I thought I would share it with you. You do not have to create an account to use the resources, but you have the option to do that if you wish.
Sheppard Software Math Games
“Sheppard Software offers everything from early math to pre-algebra. Students can shoot fruit, pop balloons, and even play math man (the math version of pac man!). Fractions, place value, money, and basic operations are some of the areas that are covered.” My Kinders especially loved the Fruit Shoot games!
