Students are encouraged to use base 10 blocks to show regrouping skills when it's first introduced. They create the top number in base 10 blocks, and then physically move a ten to the ones place when we need to regroup.
The first 12 cards have base 10 blocks printed on them so students can cross them out (when laminated, dry erase markers work great) or students can use real base 10 blocks. A follow-up sheet is included to check for understanding.
The next set of 12 have the ones and tens place with a line drawn through them, so students can focus on the ones and tens place. Some of my students still use base 10 blocks with this set, but some students are becoming more independent as they practice this concept. A follow-up sheet is included with the tens and ones split, similar to the cards.
The last set of 12 are subtraction (no lines, no base 10 blocks). A worksheet is included for students to complete. This can also be used as a center once students have become more confident!
Also included in this set is a poster for students to refer to as they master this concept.
All problems are two-digit since students are just learning this concept.
I hope you find this packet useful. Please download the free preview to view and use the poster!
