Free Trials from Mathalicious
If you were on a free trial on Mathalicious but hadn't yet signed up for a paid account, then your account was not migrated to Citizen Math. You can sign up for a brand new account on Citizen Math.
Expired Mathalicious Subscriptions
If you had an account on Mathalicious -- meaning you could log in -- but your paid subscription expired, then your account was not migrated to Citizen Math. You should be able to sign up with a brand new account.
Access to Old Mathalicious Lessons
If you had an account on Mathalicious and didn't get a chance to renew before the switch but would really like access to the old Mathalicious lessons, you can still add legacy access to your Citizen Math subscription. You'll need to sign up for the All Grades Full Pack Yearly ($320/year) and then email our team to have your account swapped over to a legacy plan. You must request legacy access by May 31, 2021; and read this article explaining the expected retirement of some lessons by June 1, 2022.
