1. Monday, March 31, 2014 POTD Ms. Tyler bought 4 types of crayons. She bought 30 of each kind. She also purchased some markers, but bought 5 times as many markers as crayons. How many markers did Ms. Tyler buy?

2. POTD Answer Ms. Tyler bought 4 types of crayons. She bought 30 of each kind. She also purchased some markers, but bought 5 times as many markers as crayons (this means the amount of markers is greater!!). How many markers did Ms. Tyler buy? 4 types of crayons x 30 each = 120 total crayons Crayons x 5 = markers so, 120 total crayons x 5 = 600 markers

3. Multiplication as Comparisons • Define the following terms • Factor • Product • Multiplicative Comparison is a situation in which one quantity is multiplied by a specified number to get another quantity. • compares two quantities by showing that one quantity is a specified number of times larger or smaller than the other • It helps to remember that the equal sign really means "is the same as." • EX: 4 groups of 7 • 4 x 7 is the same as 28. • 28 is the same as 4 x 7. • 28 is the same as 4 sets of 7. • 28 is 4 times as many as 7.

4. Let’s Practice  • 64 is eight times as many as... • 42 is six times as many as... • 35 is five times as many as... • 99 is nine times as many as... • 8 x 9 = 72 72 = 8 x 9 72 is 8 times as many as 9 72 is 9 times as many as 8 • 3 x 6 = 18 2 x 5 = 10 6 x 4 = 24 3 x 7 = 21 • 4 x 5 = 20 6 x 7 = 42 7 x 8 = 56 9 x 4 = 36

6. Tuesday, April 1, 2014 POTD Mrs. Talton is having a party. She needs 100 ounces of chocolate for her fondue machine. At the store, she can only buy 8 ounce and 12-ounce packages. What is the least amount Mrs. Talton can buy and still have enough for her party?

7. POTD Answer Mrs. Talton is having a party. She needs 100 ounces of chocolate for her fondue machine. At the store, she can only buy 8 ounce and 12-ounce packages. What is the least amount Mrs. Talton can buy and still have enough for her party? 7 packs of 12-ounces= 84 ounces 2 packs of 8-ounces = 16 ounces Total of 9 packs and 100 ounces… best answer 8 packs of 12-ounce = 96 ounces 1 pack of 8-ounce= 8 ounces Total of 9 packs but, 104 ounces…still 9 packs, but contains more ounces….

18. Wednesday, April 2, 2014 POTD JABIZ town can hold 300 students at a time. The table below shows the attendance for the last 5 days. If JABIZ town had been at max capacity, how many more people would have attended in the 5-day period?

19. POTD Answer JABIZ town can hold 300 students at a time. The table below shows the attendance for the last 5 days. If JABIZ town had been at max capacity, how many more people would have attended in the 5-day period? 1st way. 5 days x 300 max= 1500 total people. 1500 max - 989 actual = 511 more people 2nd way Find the difference each day from 300 max and add the differences together. 87+157+202+21+44= 511 more people

20. Homework Review Multiplicative Comparison Problems Write equation and use the bar model to solve. 1. Aaliyah can do 6 push-ups in one minute. Jeremiah said he can do nine times that amount.
