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.
