I apologize for causing confusion about which facts the students should be assigned to on Xtra Math. It turns out I was confused. When you follow the directions on the letter, Xtra Math will link the school account and home account. Therefore, your child's account at school will start matching the one they have been using at home.
If you have any difficulty with this enrollment, please don't hesitate to call or email me. I'm happy to provide any necessary assistance.
