Description: When learning 2-digit subtraction with regrouping, my students often get confused about when they should unbundle a ten. I created this resource with that skill in mind. Students look at a problem and must decide if they have enough ones to subtract or if they need to unbundle a ten. This resource will give your students the confidence to solve 2-digit subtraction with and without regrouping problems.
