Wylie's Learning Lagoon - Fraction Edition - Part 4 of 9

Let’s add and subtract fractions this week as we explore Grade 4 content and benchmark MA.4.FR.2.2


Save Wylie’s Weekly Problem below to use with your students:


How can we support students in learning this concept?


Before students see this problem:

  • Continue learning from grade 3 by having students name fractions and then write an equation based on a model - such as the problem below.


  • Focus on the final shaded area as the sum of the fractions shown on the left of the equation.


  • Introduce students to other methods of modeling fraction addition and subtraction, including number lines and drawings


Give students this problem:

  • Give students time to work on the problem on their own, encouraging them to select a method that works best for them.

  • Have students compare their sums and methods with partners or a small group.


  • Discuss the sum and methods used as a whole group - ask students to justify why a given sum and model is or is not correct for the problem.


After students see this problem:

  • Give students the model below.


  • Ask students to come up with 3 different expressions that have a sum shown in the model.


  • Ask students to come up with 3 different expressions that have a difference shown in the model.


  • Give students time to work independently or in small groups to complete the task, then list all expressions for the class to see


  • Give students time to look through the list of expressions and determine if they agree that all have a sum or difference equal to the value in the model

    • If expressions do not, ask students to justify why not and ask how the expression can be changed to have the same sum
