I have asked my principal for permission to not use the math workbooks and to just try using the Montessori materials and lessons. I was granted permission with the condition that if I saw it wasn't working to go back to the traditional material. So I am giving the chapter tests and trying to use my Montessori materials to teach the material covered in each chapter in addition to the sequence of Montessori lessons and individual work time.
I gave a pre-test of chapter 2 hoping I could move on but many children did not understand the concepts. So I have been doing partner work and lessons on making quanities.
I have one group (maybe half) that "get it". The others I am a little frustrated with as they are still having to count the 3 bead units and don't "see" that 1 bead and 2 beads make 3. Even though we have been writing number sentences with sets, they still don't get that their first number has to be how much is in their first set. Am I just expecting too much? I know they didn't have Montessori preschool or Kindergarten but I really thought that being 6 and 7 this would come much faster for them. Any thoughts?
