Evan's dog weighs 7 times as much as Oxana's dog. Together, the dogs weigh 72 pounds. How much does Evan's dog weigh?

Multiplication model

Let "n" represent how much the dogs weigh. What do they weigh in total?

How many boxes are there? How much do the two dogs equal together?

8 x ? = 72

The value of "n" is how much whose dog weighs? Oxana or Evan's?

if Evan's dog weighs 7 more, we need to use 7 in the equation. Multiply it with how much Oxana's dog weighs.

How much MORE does Evan's dog weigh. Evan goes in the bigger box with 63 because that is his weight. 9 and Oxana go in the small box

take Evan's weight (63) and subtracts Oxana's weight (9). What does 63-9 equal?

The value of "n" is 54

Multiple Choice

The value of n is

• how much more Evan's dog weighs

• how much more Oxana's go weighs

This is a hard lesson, let's do the homework together!

Stacey made a necklace using 4 times as many blue beads as red beads. She used a total of 40 beads. How many blue beads did she use.

We need 4 blue boxes because she used 4 times more. We only need one red box. In total, there are 40 beads.

There are 5 boxes, but we don't know how many in each box. ?x8=40. 5!

Number of blue beads, take 5 x # of boxes blue has (4)

How many boxes do we need for monkeys?
