## Learning Coach Notes:

Lesson # Lesson Title Notes
1 Triangles
• When your student completes the activity in this lesson have them check their work with the answer key circling what they got wrong. Go through any problems they got wrong and discuss how to correct it.
• In their Math notebook have your student write a description of the types of triangles they learned about (equilateral, isosceles, scalene and right triangles) and include a picture of each type.
• When your student completes the activity in this lesson have them check their work with the answer key circling what they got wrong. Go through any problems they got wrong and discuss how to correct it.
• In their Math notebook have your student write the definition of a quadrilateral, parallelogram and trapezoid. Have your student draw a trapezoid, and draw and label the parallelograms (rectangle, square, and rhombus).
3 Polygons
• When your student completes the activity in this lesson have them check their work with the answer key circling what they got wrong. Go through any problems they got wrong and discuss how to correct it.
• In their Math notebook have your student write the definition of a polygon, regular polygon and irregular polygon. Have them draw examples of each.
4 Symmetry in Shapes
• When your student completes the activity in this lesson have them check their work with the answer key circling what they got wrong. Go through any problems they got wrong and discuss how to correct it.
• In their Math notebook have your student write what symmetry means and draw an example of symmetry.
5 Lines of Symmetry
• When your student completes the activity in this lesson have them check their work with the answer key circling what they got wrong. Go through any problems they got wrong and discuss how to correct it.
• In their Math notebook have your student write down the different types of lines of symmetry a figure can have and draw an example showing each type (a shape with a horizontal line of symmetry, a shape with a diagonal line of symmetry and a shape with a vertical line of symmetry). Next have them record the rule for the lines of symmetry in regular polygons and draw an example illustrating the rule.
6 Tessellations
• When your student completes the activity in this lesson have them check their work with the answer key circling what they got wrong. Go through any problems they got wrong and discuss how to correct it.
• In their Math notebook have your student draw some tessellations.

## 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?
