  3. What is Multiplication? • Multiplication is just repeated addition! • It is a fast way of adding a series of numbers. • Examples: 2 x 4 = 8 • Look: 2 + 2 + 2 +2 = 8 • 3 x 3 = 9 • Look: 3 + 3 + 3 = 9

  4. What is multiplication cont. • When you multiply numbers, you multiply the factors. The answer you get is called the product. • 4 x 1 = 4 factor product factor

  5. Word Problem examples: • Multiplication can be used to solve all types of every day problems. For example: • You make $2.00 an hour. You work 3 hours a week. How much money do you make a week? • $2.00 X 3 hours = $6.00 • You make $6.00 per week. • Multiplication is repeated addition: • 2.00 + 2.00 + 2.00 = $6.00

  6. Word problems Cont. • You are making a batch of cookies. The original recipe calls for 1 egg. But you need to triple the recipe. How many eggs do you need? • 1 egg X 3 recipes = 3 eggs • See, multiplication is repeated addition! • 1 egg + 1 egg + 1 egg = 3 eggs

  7. Examples… There are 2 students with 2 apples each. The teacher has no apples. These students give their apples to the teacher. How many apples does the teacher have now?

  8. Student 1 + + Student 2 = ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ = Teacher
