Do Now (3 -5 min): Teacher hands a DN Worksheet to every student and asks the students to complete the worksheet independently.
Opening (2 -3 min): Teacher quickly reviews answers to the Do Now and then says, “Today, we are going to review addition. We will be learning about column addition. By the end of this lesson, you will know be able to add whole numbers up to 4 digits using column addition.”
Direct Instruction (10 min): The teacher will be teaching column addition to the students. The column-addition method for adding 2 – 3 digits numbers:
1. Draw lines to separate the 1s, 10s, 100s, and 1000s place.
2. Add the numbers in each column. Write each sum in its column
3. If there are 2 digits in the 1s place, trade 10 ones for 1 ten.
4. If there are 2 digits in the 10s place, trade 10 tens for 1 hundred.
5. If there are 2 digits in the 100s place, trade 10 hundreds for 1 thousand.
After the teacher reviews the method in which everyone will be adding today. The teacher writes an example on the board/chart. See Example Chart_4 Digit Addition. The teacher should model the first example problem and 1 – 2 more problems
Guided Practice (10 min): The teacher puts up the Guided Practice chart (See Example Chart 4 Digit Addition) and the students use graph paper to complete the problems while the teacher circulates to assist.
Independent Practice (10 min): Each student is given a piece of graph paper and asked to copy the problems from the IND Practice Chart. The students should be asked to complete it individually and turn it in.  
Closing (2-3 min): Teacher calls the attention of the students back toward the front of the class to ask what they learned about.
