This pack contains a variety of activities that can be used to review three digit addition and subtraction, with and without regrouping. The activities offer a more interesting alternative to a skill and drill worksheet and serve as a supplement to your regular math curriculum.

The activities contained within are intended for use in reinforcing the standard algorithm, once the concepts of multiple digit addition and subtraction are firmly in place.

However, as with any teaching resource, this pack can be used at the teacher's discretion. You can use the unit to provide engaging practice with the standard algorithm (relate the strategy to a written method) or as you introduce the concept of regrouping (composing and decomposing tens and hundreds) using models. I usually have my students use a set of models and a place value mat next to their assignment. They use the models to complete each step of the problem and transfer that information to their worksheet.

Feel free to modify the activities to meet the needs of your students.

The following is included in this pack:

-Suggestions for Use/Description of Activities
-Roll a Number Sentence-Addition (students roll a die to build two numbers, then add them together)
-Roll a Number Sentence-Subtraction (students roll a die to build two numbers, then subtract them)
-Spin a Number Sentence-Addition (students use a paperclip spinner to obtain two numbers; they add those numbers together)
-Spin a Number Sentence-Subtraction (students use a paperclip spinner to obtain two numbers; they subtract those numbers)
-Pick a Card- (students pick 2 cards and add them together; partners compare sums)
-Five in a Row- (students roll 2 number cubes, subtract those numbers, cover the answer on the game board; first to get 5 in a row, wins!)
-Sort it Out- (students solve a variety of three digit addition and subtraction problems, then sort them into the categories regrouping or no regrouping)
-Match Up- (students match up beach themed number sentence cards with the correct answer card; a student recording sheet and answer key are included)

This pack is aligned with the following Common Core standard (with an emphasis placed on relating "the strategy to a written method"):

2.NBT.7 Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.

Thanks for updating the game : )

This week I am being observed and I needed an introduction/review adding lesson. I teach third grade and gave a pre-assessment that illustrated how diverse my students adding abilities are. I am going to use the "Roll a Number Sentence" activity. I think the kids will love it! I wanted to scaffold the activity by forming three leveled groups. Could you possibly make a two digit and four digit activity sheet? I would be willing to pay you. I think it would end up being a great differentiated lesson!

That sounds like a great idea! I would certainly be willing to create a Roll a Number Sentence mini pack fir varying levels of abilities as I would find the materials useful myself. Could you email me at amslzr@gmail.com to discuss further? Looking forward to hearing from you!

Hi. These activities look great. On the directions for "Roll a Number Sentence" you used a comma before write it down and then in number three you used a semicolon. I was wondering if the semicolon should used be in both sentences?

Hi,

Yes, a semicolon should be used in both. I cannot believe that I did not catch that (nor did my editor). Yikes! Thank you for bringing it to my attention. I am updating the file now.

Please be on the lookout for an email from TpT/me notifying you of the update. You will then be able to download the corrected version. Thanks!
