Two and Three Digit Addition: Puzzle
Adding Two-, Three-, and Four-Digit Numbers (Practice Sheet 1)
Adding 3-digit Numbers with Regrouping-Money
Obtain some one-inch square graph paper and cut it into strips of ten squares. Give these to your students along with some counters such as pennies, Unifix® cubes or chips. Tell your students that each square can hold only one counter. Then do some hands-on addition problems that are easy, such as: get out 2 counters and put them on the strip. Now add 4 counters and put them on the strip too. Have students count to tell you how many you have in all. Write the problem on the board 2+4 = 6. Continue doing this, but make all of the answers be under 10; that way they will all fit on the strip.
Then do a trick problem such as 8 + 3. Suddenly there is no room for the extra counter. What can we do? We have to get a second strip. Continue to build on these skills until you need a third strip. Repeat this game for several days before expecting students to do the operation with abstract numbers and no counters.
