We have had great success with montessori for my dd from 2nd grade thru 6th. My ds began in kindergarten and it has been great for him thru his current 4th grade. At our public charter school the 7th grade is quite different from the typical montessori classroom. I see that my daughter needs the classroom structure montessori offers in the lower grades so that she can then pursue her work with passion to the depth and width she so desires. The 7th grade is very teacher driven, not challenging enough and too loud. WE are partial homeschooling now and looking for options for next year. The school has been very flexible and really willing to work with us.
