LOL Isa, It's the Pie!
Aleks didn't help DS understand any Math, but it was great for showing me what he does and doesn't know, what to learn next, inspiring him to 'really check before he answers' and those lovely pie charts are so yummy.
We used to keep 'homework helper.com' open on a different page, and if we got to something I couldn't explain, then I'd read the directions in homework helper and teach him. Before Aleks, I couldn't teach him anything, after Aleks he got the idea that 'yes, it isn't shameful to learn something from someone else.'
Haven't used Mathletics, but call them or email them and ask for a free trial, and they Might say yes!
