2nd Grade Addition Of Numbers Lesson Plan Example

Topic: Addition of numbers

Objectives & Outcomes

• Students will be able to add two numbers in a vertical way.

Materials

• Two sets of numbers cards (one set with even numbers, one set with odd numbers)
• Whiteboard and markers
• A jump rope (optional)

Warm-up

• Review the concept of even and odd numbers and how to identify them. Ask students to give examples of even and odd numbers.
• Give each student a set of numbers cards and have them sort the cards into two piles based on the number's even or oddness.

Direct Instruction

• Introduce the concept of adding numbers that are vertically aligned (such as 1+2 or 3+4). Tell students that this is called "vertical addition."
• Use the whiteboard to demonstrate how to add vertically. Start with a single-digit number on the left and a single-digit number on the right. For example, 1+2.
• First, find the sum of the digits in the left-most number. In this case, 1+2=3.
• Next, add the digits in the right-most number. In this case, 2+0=2.
• Finally, add the results from steps 1 and 2 together to get the final answer: 3+2=5.
• Repeat this process for two-digit numbers. For example, 3+4=7.
• Ask students to give examples of vertical addition with numbers cards.

Guided Practice

• Give students practice problems to solve on paper, starting with single-digit numbers and moving on to two-digit numbers.
• Have students work in pairs or small groups to solve the problems. Have them use the whiteboard or a dry-erase marker to demonstrate their work.
• Have a few students share their answers with the class and discuss any issues or questions they had along the way.

Independent Practice

• Give students a set of addition problems to solve without assistance.
• Have students solve the problems on paper, using their grid method.
• Have students use the whiteboard or dry-erase marker to show their work and explain their reasoning.

Closure

• Review the steps for adding vertically: align the numbers vertically, add the columns, and carry the -
• ones.
• Ask students to share their strategies for adding vertically and how they used the grid method.

Assessment

• Observe students during independent practice to assess their ability to add numbers in a vertical -
• manner. Have students complete a worksheet with addition problems using the grid method, with -
• several vertical addition problems. Have students use the addition grid to solve the problems and -
• show their work. Evaluate their answers to assess their understanding of the concept.
