Did I mention Pepper is doing school online? I thought I'd share some of the cool links I've found for her. Really, you can teach your child everything they need to know, for free, online.
There is the pattern block site I already shared. If you go to their main page, they have lots of other interactive math manipulatives.
One she has really enjoyed is multiplication.com. Her especial favorites are the ice cream scoop game and the fairy game. This is a second grader who is gifted at math, but hasn't really begun multiplying yet. Yet, for the reward of fairies, she was doing 4x9.
Practicing her states.
