Where they match

How each one plays by grade

CTCMath

Grades K-12

The K to 2 levels run thin on paper practice, and owners add a handwriting or manipulative supplement there. Elementary is well attested by long-term users. The high school levels have almost no independent owner reports, and the publisher itself used to recommend CTCMath as a supplement rather than a spine past grade 6.

UnLock Math

Grades 6-12

Foundations targets kids with arithmetic gaps who need to catch up. Pre-Algebra and Algebra 1 draw the most enthusiasm for reversing math dread. Pre-Calculus is the advanced ceiling.

UnLock Math

Consistently praised

  • Ends the math tears and turns attitudes around
  • Kids work it independently, freeing the parent
  • Instant feedback and rework-until-right build confidence
  • One problem at a time reduces overwhelm
  • Constant review keeps skills sharp

Reported as challenges

  • Pricier than several online options, and recurring
  • No live class or human teacher, just chat
  • Auto-grading and drawing tools have a learning curve
  • Some advanced kids find it less rigorous

Who CTCMath fits

Best when somebody else needs to teach the math: large families juggling several grade levels, or a parent whose own math anxiety makes lessons tense. A mathy kid who needs problem-solving depth, or a young hands-on learner who still needs manipulatives, won't get enough here.

Who UnLock Math fits

Fits neurodivergent, math-anxious, or previously frustrated students, and parents who don't want to teach or grade math at all. Families chasing top-tier rigor for a STEM kid, or wanting a live instructor, will do better with Derek Owens or a live class.
