Thank you Loy58, I agree we need to proceed with caution. Do you think the 2-5 MAP would give us a better picture of what grade-level instruction he should be receiving? I'm sort of hoping to document that the 4th grade assessments are too difficult and advocate for the 3rd grade placement. It's just more difficult, since the time does not match up as well.
ruazkaz- Thank you for your suggestions as well. We actually have Beast Academy 3A and were using that as an independent work option at school. The problem is, sometimes he would need help (which is great!) but wouldn't really have the teacher available to help him with it. I'll look into Math Kangaroo, I've never heard of it.
