## Learning Coach Notes:

Lesson # Lesson Title Notes
1 28.1 Subtracting Multiples of Ten Give your student 5 subtraction problems where they have to subtract multiples of 10.
2 28.2 Shapes within a Group Have your student try to find different shapes in various objects such as toys, books, furniture, etc.
3 28.3 Sides and Corners Please have your student draw the shapes they learned about in this lesson in their math notebook and write how many sides and corners each shape has.
4 28.4 Shapes with Straws Extend the activity in this lesson to see how many more shapes your student can make using straws. Maybe have them try to create 3-D shapes as well.
5 28.5 Adding within 100 Have your student practice adding numbers horizontally by giving them a variety of addition problems to solve in their math notebook.

## 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.
