I wouldn't take away reading or free time at home for either child unless your dds wanted to! When I mentioned that we used Aleks at home, it was because our ds was bored with his math at school, absolutely *loves* math and wanted to work ahead, so for him, it wasn't a trade-off I put in place, it was his idea and something he wanted to do.
I think it sounds like the school is trying, so that would give me the incentive to gently keep pushing forward with the school. I would also add - your dds are not going to regress, so even if they made no progress forward in math this year, chances are all will be ok if they're happy with their school days.
Best wishes,
