Hi, I'm a mom to a highly gifted second grader who has lost the love to learn, at least in school. His math has not progressed in two years! The work is still all review - basic addition - and he's craving more. I am working with the school to try to get him what he needs, but the process is so slow (I requested an I&RS last year, which at least got him attention). What is out there that can replace the Pearson worksheets but still go along with the Common Core curriculum? Anything? I'm desperately seeking some way for the teacher to differentiate. Thanks so much!
