Printable Lesson Plan on Mastering Addition: Third Grade Math
Lesson Title:”Mastering Addition: Third Grade Math”
Lesson Objective: Students will be able to add whole numbers up to 100 and understand the concept of carrying and borrowing.
Materials:
Introduction (10 minutes): Start the lesson by reviewing the concept of addition. Write the number sentence “5 + 3 = 8” on the whiteboard and have students count out 8 base-10 blocks to show the visual representation of the problem.
Direct Instruction (20 minutes): Introduce the concepts of carrying and borrowing. Write an example of a problem that requires carrying on the whiteboard and have students work in pairs to solve the problem using base-10 blocks. As they work, circulate the room to provide assistance and check for understanding. Next, have students work independently to complete a worksheet that practices addition problems that require carrying. This will serve as a formative assessment of their understanding of the concept.
Guided Practice (20 minutes): Divide the class into small groups and provide each group with a set of addition problems that require borrowing. Have them work together to solve the problems, using base-10 blocks to visualize the process. As they work, circulate the room to provide assistance and check for understanding.
Independent Practice (20 minutes): Provide students with a worksheet to complete independently. This worksheet should include a variety of addition problems, including some that require carrying and borrowing.
Closure (10 minutes): As a class, review the concepts covered in the lesson and have students share any strategies they found helpful when solving addition problems that require carrying and borrowing. Next, create a class chart listing the strategies discussed.
Assessment: Formative assessment will be used throughout the lesson to check for understanding, including the worksheets completed during direct instruction and guided practice. A summative assessment will be given at the end of the unit to assess student mastery of the concept.
Note: It is important to relate the concept of carrying and borrowing to the base 10 system, and how digits represent different values based on their position. Also, Students should understand that when adding numbers in columns, if the sum of the digits in a column exceeds ten, they have to carry over the extra digit to the next column and so on.
