My dd5 (6 next week) started Alpha in May. We just started lesson 5 which is Adding +1. Yesterday we watched the video and she did 5A but didn't want to use the manipulatives because it's faster for her not to. Today I pulled out some flash cards and drilled her on the +0 and +1 facts and she had no problems with them. It wasn't lightning recall but it didn't take her more than 3 seconds to answer any of them. So should I just move to lesson 6? What constitutes mastery of a lesson? I don't want to push her through and then have her struggling later on because we didn't take the time to cover something thoroughly enough for her.
How do you go about having your children teach a lesson back to you? Or what exactly do you say to prompt that?
