Lesson Plan
Dear Volunteer Teacher,
The lesson plan provides an overall picture of what you need to teach. It is recommended that you follow the objectives and the learning outcomes stated in the lesson plan.
We suggest that that you read the chapter thoroughly and research on how to teach the topic effectively to meet the learning outcomes.
Kindly note, while the lesson plan is a guide to teach, you can also add your own teaching elements to enhance the learning process of the children.

Activities
[Contributor - Apoorva Shetty]
1. The class should be divided in three groups xy2,x2y,x2y2.
2. Each child should be assigned the group randomly along with an integer co-efficient. (Eg. 9x2y2,6xy2 etc.)
3. They need to find their team-mates and tally the total sum of the group.
4. The teacher can verify this and whichever team can get the correct tally the fastest wins.
5. You can also divide the class in this way to form polynomial expressions and add/multiply them.
