How do modern primary-school math curricula like Everyday Math, Bridges, TERC, etc. approach the "problem" of providing enough challenge to young students who are very comfortable with math and who learn math concepts very quickly relative to peers?
I'm asking because my 2nd-grader (in California) tells me that her Bridges math class is "too easy" and from what I've seen I admittedly agree with her. The class is working on concepts she "gets" already like basic multiplication. She wants more challenge.
How do primary school teachers using these new curricula deal with this problem? How do they keep the fast learners engaged given the new curricula's emphasis on group learning and avoiding "tracking" fast learners in separate "gifted" groups (like was common when I was in primary school long ago) ? If you're an elementary teacher, how do you challenge a kid who's already working 1+ years ahead of grade level and who feels like the class is moving too slowly?
