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 3D 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.
