I have never used this math program before, and the search function in the forum is not working for me today. Can anyone tell me the approximate amount of time that it takes to do a lesson? We are required to do one lesson a day. We are on lesson 1.4, and a good number of my 2nd grade students are not making adequate progress on the Recognizing Student Achievement problems. From what I understand, the first lessons are dealing with review. Does this mean that my students did not master the material in grade one? I will be very grateful for any help or insights you can provide.
