A lot of students did not practice their math facts over the summer, and are feeling a little rusty this September. Subtraction practice can be more challenging than addition, so here is a fun way to get the subtraction connections in your brain oiled and ready to go.
Minus Mission : Keep the alien blobs from overwhelming your base! Kids can adjust the range of numbers they practice, increase or decrease the speed, and work their way up through different levels.
There are lots of other fun math fact games at http://www.mathplayground.com/ASB_Index.html
Have fun! Kids, challenge your parents to a race on Math Playground!
