Pre Algebra


I have been teaching pre-algebra for 10 years. This is the best pre-algebra course I have seen. Every lesson is crystal clear. The video explanation after every practice problem is the best part of Cratoo.

My daughter was afraid of Algebra. After doing this course, she is now ready for Algebra 1. She would not do math before but I was surprised to see her watching Cratoo videos when we were driving! Thank you for building such a nice platform.

Finally, Algebra feels simple. The teachers will make every topic so easy! I was watching a few videos with my son and I thought this is so simple! Thank you.
