Understanding Fractions and Area

In this video, Miss Williamson guides fifth graders through subtracting mixed numbers with unlike denominators. The lesson includes using fraction bars and number lines to solve problems, with a focus on finding common denominators. Students are encouraged to practice independently using provided problems.

What materials do you need to participate in the lesson?

• A computer and a printer

• A textbook and a notebook

• A piece of paper, a pencil, and something to write on

• A calculator and a ruler

What is the first step in solving the problem using fraction bars?

• Add the fractions together

• Multiply the fractions

• Draw the fraction bars for the whole numbers

• Convert the fractions to decimals

Why do we need to find a common denominator?

• To simplify the fractions

• To convert fractions to whole numbers

• To ensure the fractions have equal-sized pieces

• To make the fractions larger

How do you determine the common denominator using multiples?

• By adding the denominators

• By finding the least common multiple of the denominators

• By subtracting the denominators

• By dividing the denominators

What is the purpose of using a number line in subtraction?

• To multiply fractions

• To convert fractions to decimals

• To visualize the subtraction process

• To add fractions more easily

In the example problem, what is the area of the floor not covered by the rug?

• 2 and 5/12 square yards

• 3 and 1/4 square yards

• 1 and 3/4 square yards

• 2 and 1/3 square yards
