I am the math dept chair for a high school that has an associated middle and elementary school. 75% of our class comes from our middle school, but 25% comes from all sorts of different schools. It’s tough to match their curricula with ours and I had a thought that to fill the gaps I could assign the topics they seem to be missing on IXL or DeltaMath for the summer before they join us. It would be for 15 or so students, not sure how the pricing works (not really that interested in either for wider use). Anyone have any thoughts for me about this?
