Key Concepts

  • Fractions represent parts of a whole.
  • The whole must be divided into equal parts.
  • The denominator represents the total number of equal parts.
  • The numerator represents the number of parts being considered.

Learning Objectives

  • Students will be able to divide a shape into equal parts.
  • Students will be able to identify the fraction represented by a shaded portion of a shape.
  • Students will be able to write the fraction that represents a part of a whole.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they know about fractions. Show them different real-world examples of fractions, like a pizza cut into slices or a chocolate bar divided into squares.
  • Video Viewing (7 mins)
    Play the Khan Academy video "Fraction basics | Fractions | 3rd grade | Khan Academy". Encourage students to pay attention to how the shapes are divided and how the fractions are written.
  • Guided Practice (10 mins)
    Draw several shapes on the board (squares, rectangles, circles, triangles). Divide each shape into different numbers of equal parts. Shade some of the parts in each shape. Ask students to write the fraction that represents the shaded portion. Guide them through the process, emphasizing the importance of equal parts.
  • Independent Practice (10 mins)
    Give students a worksheet with different shapes divided into equal parts. Have them shade a specific fraction of each shape and write the fraction below it.
  • Wrap-up (3 mins)
    Review the key concepts of fractions. Ask students to share real-world examples of fractions they see in their daily lives.

Interactive Exercises

  • Fraction Art
    Provide students with construction paper, scissors, and glue. Have them create artwork by dividing different shapes into fractions and coloring the parts. For example, they could make a fractional flower with petals representing different fractions of the whole flower.
  • Fraction Pizza
    Use a paper plate as a pizza. Divide the plate into equal slices. Remove some slices and ask students to identify the fraction of the pizza that is missing. This can be a hands-on way to learn about fractions.

Discussion Questions

  • What does the top number in a fraction (numerator) tell us?
