    Lesson Title:”Understanding Subtraction”

    Lesson Objective: Students will be able to understand the concept of subtraction and use subtraction to solve problems involving taking away.

    Materials needed:

  • Subtraction flashcards (or subtraction problems written on index cards)
  • Unifix cubes or other manipulatives (one set for each student)
  • Whiteboard and markers
  • “Subtraction” worksheet (attached)

    • Introduction (5 minutes): Begin the lesson by reviewing the concept of addition and the related vocabulary (e.g. “more,” “sum,” “total”). Then introduce the concept of subtraction and the related vocabulary (e.g. “less,” “difference,” “remainder”). Use the whiteboard to write the equation “7 – 3 = ?” and ask the students what the answer is. Write the equation “10 – 5 = ?” and ask the students what the answer is. Explain that subtraction is the opposite of addition and it is used to find out how many are left when some are taken away.

    Direct Instruction (10 minutes): Using the flashcards or index cards, model how to solve subtraction problems. Show the students a flashcard with the problem “7 – 3 = ?” and use manipulatives (e.g. Unifix cubes) to physically take away 3 from 7. Write the answer, “4,” on the whiteboard. Repeat this process with different problems, and ask the students to give the answer before filling it in.

    Guided Practice (15 minutes): Give each student a set of manipulatives and a subtraction problem written on an index card. Have the students work with a partner to solve the problem using manipulatives. Walk around the room and provide support and guidance as needed.

    Independent Practice (20 minutes): Distribute the “Subtraction” worksheet to each student. The worksheet includes a variety of subtraction problems that can be solved using manipulatives. Review the instructions with the students and give them time to complete the worksheet independently.

    Closure (5 minutes): Ask the students to share one problem they solved on the worksheet and how they used manipulatives to solve it. Remind the students that subtraction is the opposite of addition and it is used to find out how many are left when some are taken away.

    Assessment:

  • Observation of students during guided and independent practice
  • Completion of “Subtraction” worksheet
  • Student ability to explain how they used manipulatives to solve a subtraction problem

    • Note: This is a basic lesson plan, it is important to adjust the duration of each part according to the class dynamics and the student’s learning pace. Also, it is important to keep in mind that for first graders it is important to use manipulatives and visual aids to help them understand the concept, as well as to keep the numbers small and manageable.

    Addition Strategies Lesson Plan for Teachers

    /in , /by

    Lesson Title:Addition Strategies

    Grade Level: 1st

    Lesson Objective: Students will be able to understand and use different strategies for solving addition problems, including counting on, making a ten, and using a number line.

    Materials:

  • Addition worksheets
  • Number lines
  • Dry erase boards and markers
  • Manipulatives (e.g. counting bears, blocks)

    • Introduction (5 minutes): Start the lesson by reviewing the concept of addition and the numbers 1-10 with the students. Remind them of the symbols for addition (+) and equality (=). Then, introduce the idea that there are different strategies for solving addition problems.

    Direct Instruction (10 minutes): Introduce the first strategy, counting on. Show the students how to use this strategy by counting on from the larger number in an addition problem. For example, if the problem is 5+3, start counting at 5 and say “5, 6, 7, 8, 9, 10.” Explain that the answer is 10 because you counted on 3 numbers from 5.
    Next, introduce the strategy of making a ten. Show the students how to use this strategy by using manipulatives or number cards to make a ten and then counting how many more are needed to solve the problem. For example, if the problem is 7+5, show the students that by combining 3 and 7, they make 10. Then, they can count how many more are needed to make 5, which is 2. The answer is 12.
    Lastly, introduce the strategy of using a number line. Show the students how to use this strategy by using a number line to count how many spaces they need to move to get to the answer. For example, if the problem is 4+6, point to 4 on the number line and move up 6 spaces to reach the answer of 10.

    Guided Practice (15 minutes): Distribute the addition worksheets to the students and have them complete the problems independently. Provide assistance as needed. Ask them to use different strategies for different problems, and also have them explain their thinking process.

    Independent Practice (20 minutes): Give the students additional addition problems to solve on their own, using the different strategies. Monitor their progress and provide feedback as needed.

    Closure (5 minutes): Ask the students to share their answers and explain which strategy they used to solve each problem. Review any misconceptions and provide additional instruction as needed.

    Assessment: Observe the students as they complete the independent practice problems and the worksheets. Use this as an informal assessment to determine their understanding of the different addition strategies. Additionally, you can use a formal assessment by administering a quiz or a test on addition.

    Note: As students become more comfortable with these strategies, you can also introduce more complex problems, such as 2-digit addition. Also, encourage students to use the strategy that they feel comfortable with, and avoid forcing them to use a specific strategy.
