This packet was made to help your kiddos practice adding 2-digit numbers in the tens/ones mat. It does not include any problems with regrouping. There are 4 worksheets with an example and 15 problems each and then 3 ticket-out-the-door assessments with 4 problems each to check for understanding. If you are interested in some regrouping practice like this I have a packet for that as well. Hope that you find this useful!
