Modeling Multiplication Equations
t = 32 c = 181.42 r = 43
Correct – The solution is 2. Example 1: Willie has 8 pieces of gum to divide between his 4 friends. How many pieces of gum does each friend get? Choose the answer from the set. {2, 3, 4} 4(2) = 8 4(3) = 8 4(4) = 8 Correct – The solution is 2.
Example 2: Choose the correct answer to the equation from the set. 5(6) = 35 5(7) = 35 5(8) = 35 Correct – The solution is 7.
Example 3 : Dan has $6. 00 that he is dividing evenly among 2 friends Example 3 : Dan has $6.00 that he is dividing evenly among 2 friends. How much will each friend get? Use a scale model to solve. 2x = 6 Divide the 6 evenly between each x. x = 3
Example. 4: How many packs of paper can you buy with $35 if one package costs $7? Use the bar model to solve. 7p = 35 $35 7 7 7 7 7 1 2 3 4 5 x = 5
What is another way the bar model can be used to solve 7p = 35? x = 5
Example 5: Solve the equation using the scale model. 4x = 12
24 x = 4 Example 6: Solve the equation using the bar model. 6x = 24 4
Practice Solve using the scale model or the bar model. 3x = 15 2r = 18 6y = 72 8p = 800 x = 5 r = 9 y = 12 p = 100
