Learning Objectives

Students will be able to identify halves and fourths within whole shapes. Students will be able to create different variations of halves and fourths using the same shape. Students will be able to recognize shapes which are divided equally into fractions.


(5 minutes)
  • Take out the watermelon manipulatives, and review the concepts of the different names for the fractional pieces represented.
  • Have the students take out their circle fraction manipulatives from the previous lesson.
  • As you show the pieces of watermelon, ask the students to hold up their corresponding shape that matches, naming the corresponding equal share (fractional part). Continue with fourths and eighths.
  • Have the students put their circle fractional manipulatives away.
  • Tell the students that they are going to be slicing the same shape in different ways to create similar fractions. Emphasize that the parts of a shape must be equal.
  • Show the students “non-examples” of watermelon shapes that do not represent equal parts. Explain that fractional parts must match all of the other shapes inside the whole.
