Lesson Plan on Adding Two-Digit Numbers
Lesson Title:Adding Two-Digit Numbers
Lesson Objective: Students will be able to add two-digit numbers with regrouping/carrying.
Materials:
Introduction (5 minutes): Begin the lesson by reviewing basic addition concepts with one-digit numbers. Write simple addition problems on the whiteboard and have students solve them as a class.
Direct Instruction (10 minutes): Introduce the concept of regrouping or carrying when adding two-digit numbers. Show an example of adding 35 + 24 using base 10 blocks. Explain that when we add the ones place (5 + 4), we get 9, which is greater than 10, so we need to regroup or carry a 1 to the tens place. Show another example of adding 45 + 27 and have students work through it with you.
Guided Practice (20 minutes): Provide students with basic addition worksheets that include two-digit numbers. Walk around the room and assist students as they work through the problems. Help them to understand the concept of regrouping and carrying.
Independent Practice (20 minutes): Have students work independently on additional two-digit addition problems. Monitor their progress and assist as needed.
Closure (5 minutes): Review the concept of regrouping and carrying with the class. Ask students to provide examples of two-digit addition problems that they solved during independent practice.
Assessment: Observe students as they work through the problems, provide feedback on their progress, and evaluate their understanding of the concept.
