When I first took Math Kangaroo, there wasn’t really anything to compare to the kinds of math it contained. (…) the logic puzzle-type problems in Math Kangaroo were really interesting and had me looking forward to the competition each year.
Math Kangaroo is an amazing, high quality resource for challenging mathematicians 1st through 12th grade. They have an annual competition that schools or other sites an run. (…) They have a variety of resources and videos. I highly recommend Math Kangaroo for anyone who wants to help their child/student grow their math problem-solving/logic skills.
