September 26 2017

Tuesday 9/26/17 – Math

Welcome to Math!

Please take out:

  • Module 4 packet
  • pencil
  • Chromebook

Warm-Up:

  • Counting by 6’s: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
  • Mod 4 Are You Ready?
  • Module 4 Real-World video

Lesson 4.1: Applying GCF and LCM to Fraction Operations

Learning Target copy

 

Learning Target: Students will be able to explain the meanings of GCF and LCM and use them when adding, subtracting, and multiplying fractions.

Engage:

Suppose you want to make half a batch of muffins and the recipe calls for 3/4 cup of pecans. What amount of pecans should you use?

Getting to ISE 4.1 (Interactive Student Edition):

  • Unit: Number Operations —> Module 4: Operations with Fractions —> Lesson 4.1: Applying GCF and LCM to Fraction Operations

Explore:

  • Multiplying Fractions Example 1, p. 79
  • Dr. Burger video
  • Discuss:
    • Does the order in which you multiply two fractions matter? Explain.
    • How can you tell when it would be easier to simplify before multiplying than to simplify the product?
    • Remember that the multiplication sign x means “of.” So, 1/2 x 1/4 means “What is 1/2 of 1/4?”

Explain:

  • Do Your Turn, p. 80 (1-6).
    • Remember to simplify either before or after multiplying! Final answers should always be in simplest form.
  • Multiplying Fractions and Whole Numbers Example 2, p. 80
  • Discuss:
    • Why can you write 18 as 18/1?
  • Dr. Burger video
  • Reflect, p. 81
    • If you are taking a fraction of 18, will your answer be more or less than 18?
  • Do Your Turn, p. 81 (8-13).
    • Estimate the product first by using benchmark fractions or easier numbers.
    • Ex: 5/8 is close to 1/2. 1/2 of 24 is 12. So my answer should be close to 12. Will it be more or less than 12?
    • 1/3 x 8 is close to 1/3 x 9, which is 3. Will my answer be more or less than 3?

Homework:

  1. Do Guided Practice p. 82 (1-10).
  2. Continue working on dashboard assignments until you are all caught up.
  3. Having a hard time? Study this page on How to Solve Fraction Questions in Math.
