Unit/Lesson Overview:
These lessons came from Lessons for Extending Mulitplication by Maryann Wickett & Marilyn Burns.During these lessons, students explore factors of numbers from 1 to 50. Students gain practice with basic facts and multi-digit multiplication problems, commutative property, and understanding of the link between multiplication and division. This also adds to the students' understanding of division through having them examine rectangular arrays and representing them symbolically with division equations.

Extension:
To extend this lesson, students can discuss prime and composite numbers. Students will recognize that certain numbers have only two factors while others have more than two factors.Discussion could follow regarding the result of multiplying two odd numbers, (Odd x odd = odd), two even numbers, (even x even = even), and an odd number by an even number (odd x even = even).
|
Guiding Questions:
How many ants were chasing the littlest ant? What other ways could they have lined up?What do you notice about the even and/or odd numbers? What happens when there are left over ants that aren't in lines with all the other ants?
|
Summary Questions:
What did I notice about my numbers?What did I notice about my arrays? Can I tell all of the factors of a number?
