Important — please read before you order: Math-U-See's digital instruction is now a 1-year subscription, not lifetime access. The older digital version stayed with you for good; the new access card activates your online instruction for one year. If you were counting on the old forever-access, this is the change to know about. The good news: the card isn't tied to the level on this page. It carries two course credits you can spend on any two Math-U-See levels, plus five student accounts, so one card often covers two kids. If a student finishes early or needs to review, you can move a credit to a different level from your dashboard once every 30 days. And the year doesn't start until you redeem the code, so buying now for a fall start doesn't cost you any of it.
