I will introduce third graders to the fundamentals of multiplication
(1) How multiplication is a quicker and neater form of addition
(2) How numbers in multiplication are placed into groups (or sets)
(3) How students within the classroom can simulate the concept of groups and
(sets) to construct the visual effect of multiplication by way of forming
groups of (2's) (3's) and (4's)
papers folded in half, thirds and forth
prop used to show an example of groups, pairs or sets
Students will learn to add numbers and objects but the count will be equal in
numbers and amounts
Students will learn with repeat addition that the larger your sum the longer and
tedious your operation
Students will learn that addition is a slow type of multiplication
ex. 3 groups of 2's is 2+2+2=6
Students will reverse the order of 3 groups of 2's to 2 groups of 3 both
operations will equal 6 as a product
Students will learn to put problems into simple word problems - ex. If 2 stamps
cost 3 cents each how much will they cost? 2 groups of 3 is the same as 3+3=6.
Six is your answer.
Students will take 3 sheets of paper that have lines dividing it into halves,
thirds and quarters. Horizontal lines interval of one inch from top to bottom.
Students will fold all 3 sheets along the fold lines.
Students will be given a problem 3 groups of 2's. The student will then take
the paper folded in halves and then the student is to tear 3 groups of the
horizontal lines so that they hold 3 strips the students will now count each
fold which should equal 6.
Students will work cooperatively in groups of 3's.
This program is design as an introduction of multiplication for third graders.
I feel that the strips of papers can be another option for the teacher so that
the class does not become to "cut an dry".
