Free 2nd Grade Fractions Lesson Plan (Math)

Topic: Introducing the concepts of fractions

Objectives & Outcomes

• By the end of this lesson, students will be able to identify and understand basic fractions, including halves, thirds, fourths, and eighths.

Materials

• Cardstock or construction paper
• Scissors
• Glue
• Markers or crayons

Warm-up

• Ask students if they have ever seen a fraction before. Ask them to describe what the fraction looks like and what it might be used for.
• Show students a picture of a fraction, such as a third, and ask them to describe what they see. Ask them to use their own words to describe what a fraction is.

Direct Instruction

• Introduce the concept of a fraction as a part of a whole. Show students a whole object, such as a piece of fruit, and ask them to identify all the parts of the whole object.
• Next, show students two parts of the whole object and ask them to identify which part is smaller and which part is larger.
• Introduce the names for the parts of a fraction: the numerator is the top part of the fraction, and the denominator is the bottom part of the fraction.
• Show students different examples of fractions, such as one half and three quarters, and have them identify the numerator and denominator of each fraction.
• Have students work with a partner to create their own fraction by dividing a whole object into equal parts.

Guided Practice

• Have students work with a partner to identify the numerator and denominator of each fraction shown on the board.
• Have students work with a partner to create their own fractions by dividing a whole object into equal parts.
• As a class, discuss and compare the fractions created by the students.

Independent Practice

• Have students work on a project-based activity in which they create a model of a scene or object using fractions to represent the size of the different parts. For example, they could create a model of a classroom where each student represents a fraction of the class (e.g., 1/5 of the class) and they have to work together to create a functional classroom.

Closure

• Review the main points of the lesson-fractions can be used to represent parts of a whole, they can be added and subtracted, and they can be written as a fraction bar or as a fraction-decimal combination.
• Ask students to share their project-based activities and how they used fractions to represent parts of a whole.

Assessment

• Observe students during independent practice to see if they are able to use fractions to represent parts of a whole and use proper notation.
• Collect and review the projects-based activities to assess understanding of the concept of fractions.
• Administer a brief quiz to assess student understanding-have students work through a few problems using fractions to represent parts of a whole, have them write the fractions as a fraction bar or as a fraction-decimal combination, and have them add and subtract the fractions.
