## Learning Coach Notes:

Lesson # Lesson Title Notes
1 Dividing Number Lines
2 Identifying Fractions on a Number Line In their Math notebook have your student draw a number line that goes up to 10 and label where the fractions would be.
3 Equivalent Fractions In this lesson have your student complete the practice activities first before looking at the answer keys. Be sure to monitor this. When they check their answers using the key have them circle what they got wrong and talk about why they got it wrong and make corrections.
4 Common Denominators In this lesson have your student complete the practice activity first before looking at the answer key. Be sure to monitor this. When they check their answers using the key have them circle what they got wrong and talk about why they got it wrong and make corrections.
5 Greatest Common Factor Have your student practice finding the GCF by giving them five different pairs of numbers and finding the GCF for each pair. Then have them find the LCM for each pair using the GCF like it was taught in the lesson. They can write their work in their Math notebook.
6 Least Common Multiple Have your student practice finding the LCM by giving them five different pairs of numbers and finding the LCM for each pair in their Math notebook. In this lesson have your student complete the practice activity first before looking at the answer key. Be sure to monitor this. When they check their answers using the key have them circle what they got wrong and talk about why they got it wrong and make corrections.

## Module Guiding Questions:

When a student starts a lesson ask them questions to check for prior knowledge and understanding and to review concepts being taught. At the end of the lesson ask the questions again to see if their answer changes.

## Module Video Questions:

When a student watches a video take time to ask them questions about what they watched. Suggested questions for the videos in this module are listed here. Suggestion: Have the student watch the entire video first all the way through. Then have them watch the video a second time, as they watch it pause the video and ask the questions.

## Module Suggested Read Aloud Books:

Take time to read to your student or have them read aloud to you. Read a different book each day. While reading the book point out concepts being taught. You may purchase these books or find them at your local library. Suggested things to discuss while reading the book:

• What is the main idea?
• What are three things new you learned?
• How does this book relate to what you are learning about?
