The student will
b)   estimate solutions and then solve single-step and multistep practical problems involving addition, subtraction, multiplication, and division of fractions. 
Essential Knowledge and Skills
  • Solve single-step and multistep practical problems that involve addition and subtraction with fractions and mixed numbers, with and without regrouping, that include like and unlike denominators of 12 or less. Answers are expressed in simplest form.
  • Solve single-step and multistep practical problems that involve multiplication and division with fractions and mixed numbers that include denominators of 12 or less. Answers are expressed in simplest form.
Essential Understandings
  • What is the role of estimation in solving problems?  Estimation helps determine the reasonableness of answers.

Explore Learning
  1. Adding Fractions (Fraction Tiles): Add fractions with the help of the Fractionator, a fraction-tile-making machine in the Gizmo. Model sums by placing the tiles on side-by-side number lines. Explore the usefulness of common denominators in adding. Express sums as improper fractions or mixed numbers.
  2. Dividing Fractions: Divide fractions using area models. Adjust the numerators and denominators of the divisor and dividend and see how the area model and calculation change.
  3. Dividing Mixed Numbers: Choose the correct steps to divide mixed numbers. Use step-by-step feedback to diagnose and correct incorrect steps.
  4. Fractions with Unlike Denominators: Find the sum or difference of two fractions with unlike denominators using graphic models. Find the least common denominator graphically.
  5. Multiplying Fractions: Multiply two fractions using an area model. Vary the vertical area to change one fraction and vary the horizontal area to change the other. Then examine the intersection of the areas to find the product.
  6. Multiplying Mixed Numbers: Choose the correct steps to multiply mixed numbers. Use the step-by-step feedback to diagnose incorrect steps.
