Lesson Plan : Multiplication Discovery

Teacher Name:
 Leigh Belford
Grade:
 Grade 3
Subject:
 Math

Topic:
 Students will use tiles to create arrays.
Content:
 Drawing arrays and using manipulatives as a strategy to discover multiplication facts.
Goals:
 Students will discover multiplication facts using manipulatives and drawing models.
Objectives:
 TLW create arrays using manipulatives and drawings for a given product.
Materials:
 area model squares (24 per student); 12 classroom chairs; dry erase or chalk board; math journal or paper to record learning
Introduction:
 Put 12 chairs in front of the room. Give students the scenario "I want to set up these 12 chairs to create a classroom auditorium. What are the possible ways we could set up the 12 chairs to be in neat rows."
Development:
 Students work as a team to create possible chair arrangements using 12 chairs. Arrangments are recorded on the board using dots to represent each chair.
Practice:
 Students copy arrangments from the board. Teacher guides students to write multiplication facts that are represented by each model.
Accommodations:
 Students could work with a smaller number of chairs (perhaps 16) though this lesson seems to differentiate iteself. More advanced students are able to create all combinations while other students only create a few in the alloted time BUT all are successful.
Checking For Understanding:
 Teacher checks for understanding by monitoring students while they are doing the activity. Teacher can also see student work by viewing their math journal at a later time.
Closure:
 Students are able to 'donate' solutions to classmates in an effort to find all the combinations.
Evaluation:
 Students are beginning to understand the concept of multiplication and will soon begin to memorize tables AFTER they have a clear understanding of the concept of multiplication.
Teacher Reflections:
 This lesson was successful and I will suggest it to my other 3rd grade colleagues.
