Workshop: Add and Subtract Fractions

This Workshop provides opportunities to review and practice strategies for adding and subtracting fractions. Prepare to observe and assess students' use of these strategies using the following Expectations:

E1.

Identify and find equivalent fractions using tools (e.g., area models, number lines) and multiplication and division strategies.

E3.

Represent addition, subtraction, multiplication, and division of fractions with area models, number lines, and number sentences.

E5.

Solve word problems involving addition, subtraction, and multiplication of fractions.

E8.

Add and subtract fractions including those with unlike denominators using area models and paper-and-pencil methods.

E9.

Estimate sums and differences of fractions using benchmarks and mental math strategies.

E10.

Find common denominators and use them to add, subtract, and compare fractions.

Students will identify their level of confidence with a particular concept and choose problems from Workshop Menus. Use your own evaluation of students' progress to help guide their choices. See the TIMS Tip for more about Workshop Menus.

Plan to organize the class into partners, small groups, or stations based on the problems chosen from the menus. Students may work with different groups or partners as the Workshop progresses.

Students will have an opportunity to play Circle Duets or Closest To near the end of the Workshop. Distribute the game materials you collected at the end of Lesson 3 and Lesson 5. Make copies of the Closest To Recording Sheet Master so that students will have new recording sheets for the Workshop game.
