## Reflection: Lesson Planning Problem Solving with Triangles - Section 2: Problem solving

There are times in teaching when you have to miss class either for a meeting or due to illness. When I miss school, I many times leave problems for the students to work. Today is an example of what I do.

As many of you know there are good substitutes and then there are those that just 'babysit.' When I know I will be absent I always request certain substitutes I also have a list that I ask not to be used in my class.

When a class has a substitute teacher, students will need to depend on each other for assistance. I provide the teacher with my diagrams for the problems. Students may come up with other diagrams that will also be appropriate. The substitute will have the option of allowing students to put problems on the board and discuss the problems as a class.

I leave the bell work problem with the questions and answers I expect.
