Well, today only you can get their iLiveMath Animals of Africa for FREE :) Gotta love that. I'll confess, I've downloaded it, and just barely played with it. I can tell you that it features beautiful photos, and lots of interesting animals in the problems.
Level 1 has problems such as: In an African animal preserve there are 3 peacocks and 4 hippopotami. What is the sum?
Level 2 has problems such as: A tracker followed a crash of 39 rhinos and a drove of 23 cattle. How many animals were tracked?
Level 3 has problems such as: Last month we saw 85 hyenas. This month we saw 8 times as many hyenas. How many total hyenas were seen?
Here's a blog post about the freebie. Go get yours.
