I know that the whole point behind Math U See is for students to master each lesson before moving on, so really it could take any amount of time to complete each lesson in each level of Math U See...
How quickly do you and your children make it through a level of Math U See? I'm just trying to get a general idea because it seems like we might go through Alpha pretty quickly and might need to follow up with Beta before the end of the year.
Does one level of Math U See last you a full school year? Or do you tend to do two levels in one year?
