Title: Introduction to Fractions

Grade level: 3rd grade

Objective: Students will be able to identify and understand fractions as parts of a whole.

Materials: - Fraction manipulatives (circles, squares, rectangles) - Whiteboard and markers - Fraction worksheets - Fraction game (optional)

Procedure:

Introduction (10 minutes): 1. Begin by asking students if they have ever shared a pizza or a cake with someone. Ask them how they decided how much each person would get. 2. Introduce the concept of fractions as a way to represent parts of a whole. Write the definition of a fraction on the board: a fraction is a part of a whole. 3. Show students different fraction manipulatives and explain that they can be used to represent fractions.

Direct Instruction (20 minutes): 1. Demonstrate how to represent fractions using the manipulatives. For example, show how to represent 1/2 using two equal parts of a circle or square. 2. Have students practice representing different fractions using the manipulatives. 3. Write different fractions on the board and have students identify the corresponding manipulative.

Guided Practice (15 minutes): 1. Distribute fraction worksheets to students. 2. Have students complete the worksheets, using the manipulatives to help them. 3. Circulate around the room to provide assistance and answer questions.

Independent Practice (15 minutes): 1. Divide students into pairs or small groups. 2. Provide each group with a set of fraction manipulatives and a fraction game (optional). 3. Have students play the game, using the manipulatives to represent fractions.

Closure (5 minutes): 1. Review the definition of a fraction and ask students to share one thing they learned about fractions today. 2. Collect the fraction worksheets and fraction manipulatives.

Assessment: - Observe students during the guided and independent practice to assess their understanding of fractions. - Collect and review the fraction worksheets to assess individual understanding. - Use a formative assessment tool, such as a quiz or exit ticket, to assess overall understanding of the lesson.
