In 2014 we were introduced to CTCMath and discovered the benefit to an online school program and the joy that can be found with such an addition to our homeschool day. CTCMath has been renewed in our homeschool going on our third year, and we are reviewing this one-year subscription to CTCMath Homeschool Membership thanks to our participation with the TOS Homeschool Review Crew. What a blessing this is! CTCMath is an online math program. We successfully use it on my iMac desktop, Linux-based Ubuntu laptop running a moderated Chrome browser, iPad1, iPad2 both in the Safari browser with little to no issue. We’ve enjoyed it in years past, and this year my turning-five-years-old-next-week daughter is really getting the benefit of the program as well! We use the program daily during the weekday and sometimes on weekends as well. The girls are both eager to work with CTCMath and consider it a reward. . .
