Using the problem solving method, this lesson focusses on using mental math and estimation to solve addition and subtraction problems.
There are four parts to my lesson:
1. Moving Your Mind
In this section, the teacher will spend about five to ten minutes to get the student's minds thinking about the concept that will be discussed in the lesson.
2. The Problem
In partners, students work through the problem. This should take approximately twenty minutes.
3. Making Sense Of It
The students will now share their work, explaining to the class how they solved the problem. Not every student will present, just the ones that the teacher selects that will be able to show different strategies the students used to solve the problem. Attempt to select a variety of strategies. Ensure that the teacher clears up any misconceptions.
4. Show What You Know
The students will now answer a problem that is very similar to the one they worked on in a partnership. This is the independent practice. The teacher will be able to quickly check who understands it and who does not. This can guide your next math lesson.
