This packet was made to help your kiddos practice regrouping when adding 2-digit numbers. I use the tens/ones workmat, but also add 2 ten frames on the ones side for the kids to SEE how their numbers form another 10. There are 4 worksheets with 6 problems each and then 2 ticket-out-the-door assessments with 2 problems each to check for understanding. Hope you are able to use this in your classroom and that it really helps your kids!!
