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 and add those numbers together; also includes a blank spinner)
*Spin a Number Sentence-Subtraction (students use a paperclip spinner to obtain two numbers to subtract those numbers; also includes a blank spinner)
*Pick a Card- (students pick 2 cards and add them together; partners compare sums)
*Solve, Cut, Glue Flap Book-Addition (students solve a set of addition problems, cut them out, and glue them beneath the correct flap)
*Solve, Cut, Glue Flap Book-Subtraction (students solve a set of subtraction problems, cut them out, and glue them beneath the correct flap)
*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)
*Word Problem I Spy (students go around the room to solve a set of word problems; a recording sheet and answer key are included)
*Match Up- (students match each number sentence card with the correct answer card; a recording sheet and answer key are included)
*Scoot Addition and Subtraction Mixed (students scoot from desk to desk on your cue and solve the addition/subtraction problem posted at each desk; a recording sheet and answer key are included)
