  1. LearningMultiplication With Snowmen Group 9 KindellHolst(Group Leader) Dale Boyett Dexter Ivy Matthew Forrester Nathan Wolfford Codi Steiner

  2. Target Audience • This lesson is for third graders who are just learning what multiplying is and how to use it.

  3. Applications of Multiplying • Multiplying is simply repeated addition, used so that large numbers can be found from groups of smaller numbers. • Eight total snowmen in two groups of four.

  4. Multiplying from Addition • Multiplying is adding on a larger scale. Looking back to the previous picture, there were two columns of snowmen. Each column had four snowmen. Adding the snowmen individually gives 8 total snowmen.

  5. Multiplying from Addition • With multiplying, however, you see that adding two groups of four snowmen gives eight total snowmen. Multiplying is repeated adding.

  6. Multiplying Example To the right is another example of multiplying as repeated adding. Adding the marbles in groups gives the equation 3 + 3 + 3 + 3 = 12. If each three is a set, then multiplying would give the equation 3 x 4 = 12, because there are four groups of three.

  7. Multiplication Table • A multiplication table has a row of numbers and a column of numbers. By matching the two numbers needed to multiply, one can find out the product (the answer from two numbers multiplied together).

  8. The Scratch Program • The Scratch program accompanying this presentation has the student enter in two numbers. The first number represents the rows and the second represents the columns. The program then asks the student what they think the answer is.

  9. The Scratch Program • After the program asks for the input, it displays snowmen in rows and columns and checks the students answer. This allows the student to learn as they go along! Three columns of two snowmen each!
