Lesson Title:Introduction to Subtraction

Lesson Objective: Students will be able to understand and use subtraction to solve real-world problems.

Materials:

Subtraction flashcards (numbers 1-20)

Subtraction worksheets

Subtraction board game

Dry-erase boards and markers

Manipulatives (e.g. base ten blocks, counters)

Introduction (10 minutes):

Begin the lesson by reviewing basic addition facts with the class. Ask students to give examples of addition sentences, and write them on the board.

Introduce subtraction as the opposite of addition. Explain that subtraction is a way of finding out how many more we need to add to make a certain number.

Show an example of a subtraction sentence (e.g. 8 – 5 = 3) and ask students to explain what it means.

Direct Instruction (20 minutes):

Show students the subtraction flashcards and have them practice solving subtraction problems by counting backwards from the larger number.

Use manipulatives (e.g. base ten blocks or counters) to physically model subtraction problems for students.

Have students work on the subtraction worksheets to practice solving subtraction problems independently.

Guided Practice (25 minutes):

Divide the class into small groups and give each group a subtraction board game.

Explain the rules of the game and have students take turns rolling the dice and solving the subtraction problems on the game board.

Monitor students as they play the game, and provide feedback and support as needed.

Independent Practice (15 minutes):

Give students dry-erase boards and markers, and have them solve subtraction problems independently.

Walk around the room to check their work and provide feedback.

Closure (10 minutes):

Review the key concepts of subtraction with the class.

Have students share an example of a subtraction problem they solved during the lesson and explain their thinking.

Assign homework related to subtraction and set a date for a quiz on subtraction.

Assessment:

Observation of student participation and engagement during the lesson

Completion of subtraction worksheets and board game

Quiz on subtraction concepts and problem-solving
