Student Name: Math Teacher: HIP Manager: Module # 4 of 15 Multiplying Fractions With & Without Models 7th Grade Students: Please return your completed module to your HIP teacher. Your HIP teacher will forward your completed module to your science or math teacher to make sure you receive credit for the work you have completed. Remember, your future is extremely important to us and we are here to help you! Get your next module and keep going – you will be SUCCESSFUL!!!

Math Dragon Presents “multiplying fractions with and without models”

How do you multiply fractions using models? Use the BOX method.

Box method You will need two different color writing instruments. 3 2 4 3 Step 1: Draw a rectangle. Step 2: Divide the rectangle vertically into rows by looking at the denominator of the first fraction. Then shade in the number of rows based on the numerator. Step 3: Divide the rectangle horizontally into rows by looking at the denominator of the second fraction. Then shade in the number of rows based on the numerator with a different color. Step 4: Determine your answer by counting the total number of rectangles for the denominator and the total number of squares that are shaded by both colors for the numerator. Then simplify if necessary. 6 12 1 2

Review turning a mixed number into an improper fraction We will make a MAD face to help us remember the steps. x Multiply Add Denominator stay the same 3 2 17 x 5 5 Multiply the 5 and 3 to get 15. Add 15 and 2 to get 17. The 17 becomes the new numerator. The denominator stays the same.

Multiplying mixed numbers Step 1: Turn any mixed numbers or whole numbers into improper fractions . Step 2: Reduce the first fraction if possible. Step 3: Reduce the second fraction if possible. Step 4: Reduce both fractions if possible 1 2 Step 1 1 2 1 Step 4 12 1 Step 5 1 Step 5: Multiply straight across. Step 6: Do not leave answer as an improper fraction. Reduce final answer if possible.

We will first look at multiplying monomials; then we will multiply monomials by polynomials; and finish with multiplying polynomials by polynomials.
