TODAY YOU WILL LEARN HOW TO USE REPEATED ADDITION AND DRAW AN ARRAY TO DO MULTIPLICATION

VOCABULARY MULTIPLICATION- A quick way to add the same quantity many times MULTIPLICATION- A quick way to add the same quantity many times FACTORS- The numbers that are multiplied together. EX. 5x2=10 5 and 2 are the factors. FACTORS- The numbers that are multiplied together. EX. 5x2=10 5 and 2 are the factors. PRODUCT- The answer in multiplication. PRODUCT- The answer in multiplication. EX. 5 x 2 = 10 10 is the product EX. 5 x 2 = 10 10 is the product

PROBLEM This morning at the breakfast table, there were 5 plates. There were 3 muffins on each plate. This morning at the breakfast table, there were 5 plates. There were 3 muffins on each plate. What was the total number of muffins on the plates? Discuss- How would you solve this problem?

REPEATED ADDITION This morning at the breakfast table, there were 5 plates. There were 3 muffins on each plate. This morning at the breakfast table, there were 5 plates. There were 3 muffins on each plate. What was the total number of muffins on the plates? One way to solve this problem is by using repeated addition. One way to solve this problem is by using repeated addition. 3 + 3 + 3 + 3 + 3 = 15 3 + 3 + 3 + 3 + 3 = 15

MAKE AN ARRAY You can also make an array. An array is made of rows of objects, with the same number of objects in each row. 3 rows of 5 or 3+3+3+3+3 or 3 x 5

AN EQUAL GROUPS MODEL You can also draw out a model by drawing out equal groups You can also draw out a model by drawing out equal groups

Let’s Try Another Problem Bill has 4 pencil boxes. Each pencil box holds 2 pencils. What is Bill’s total number of pencils? Bill has 4 pencil boxes. Each pencil box holds 2 pencils. What is Bill’s total number of pencils? Since there are 4 groups of 2, we can use repeated addition, an array, or mulitplication to solve. Since there are 4 groups of 2, we can use repeated addition, an array, or mulitplication to solve. 2+2+2+2 = 8 2+2+2+2 = 8 OR 2 x 4 = 8 OR 2 x 4 = 8
