I am planning on CLE math for my upcomigng first grader, but I am researching other options just in case this doesn't work for her. :)
I see many people here use Singapore and I am curious as to what made you choose this over another program. Do you switch to another program once they are in the upper grades? If so what? Also, I see a lot of people supplement when using Singapore and I wasn't sure why? Do you have to supplment? Oh, and US edition or standards edition?
Thanks!
