Rename the multiple of 10. Solve. 70 x 4 Apply the associative property, find the product, write the equation and solve.
What is 70 x 4 = (7 x 4) x 10 = 28 x 10 = 280

Number Strings: Solve the following mentally. Explain how you solved it. 99 + 38
What is taking 1 away from 38 and adding it to 99, making it 100 + 37 which would add up to 137.

9 x 6 = Split one factor and using partial products, show your answer. Work must be shown to demonstrate the partial product equations (or rectangles) solved to add and find the final answer.
What is 5 x 6 = 30 4 x 6 = 24 30 + 24 = 54 so 9 x 6 = 54

Rename the multiples of 10 in this problem: 30 x 50 Rearrange the factors, apply the associative property and find the product. Show work.
What is 3 x 10 x 5 x 10 = (3 x 5) x (10 x 10)= 15 x 10 x 10 = 1500

You solve for the product of 90 x 5 and got 450. Why are the products for 90 x 5 and 9 x 50 th same ?
What is they are the same because when you rename the multiple of 10 and rearrange the factors, you are multiplying by 5, 9, and 10 in both expressions.

An online store gives away 8 samples of peach yogurt. It gives away 4 times as many samples of honey yogurt. How many fewer peach samples does it give away ? Model the word problem, show how to solve the problem, give the final answer.
What is a model with one block for peach, representing 8 Another bar model for Honey with 4 blocks, representing 4 x 8 = 32 To find out how many fewer peach samples does it give away, you must use the model to determine there are a difference of 3 times as many for Honey. 3 x 8 = 24 The store gives away 24 fewer peach samples.

These are the steps to add groups of 7 to 5 x 7 = 35 to find out how many 7's there are in 49. (Show work)
What is: 5 x 7 = 35 +7 6 x 7 = 42 +7 7 x 7 = 49 There are 7 seven's in 49.

Dave's Goal is to write 20 reviews on his blog each week. Last week, he wrote 3 reviews each day for days. How many reviews did Dave write last week ? Did he meet his goal ? How would you model this problem ? How would you solve this problem? How many review did he write last week ? Did he meet his goal ?
What is model a bar model with 7 blocks, labeling one as 3. Solve by multiplying 7 x 3 (7 days at 3 reviews a day) Dave wrote 21 reviews. His goal was to reach 20 and he met his goal, yes.

Katie is selling iPhone 7s in a family plan that comes in groups of 4 phones. She gets a bonus if she sells more than 45 iPhones. She sells 10 family plans, did she make a bonus? If not, how many more family plans does she need to sell to get a bonus? Show how to solve using a bar model.
What is: Equal groups problem Draw one bar, split up into ten groups of 4. Label the variable on top of the bar. n = 4 x 10 n = 40. She has sold 10 family plans with 40 phones total. She needs to sell two more family plans, or 8 more phones to have sold more than 45 phones and get her bonus.

Solve for the following question using a bar models to represent your answer. Raj makes 50 marketing calls. Fiona makes 8 times as many marketing calls. How many more marketing calls does Fiona make?
What is: Compare Problem. Draw one bar to show Raj's 50 marketing calls. Draw a longer second bar and split it into 8 equal groups of 50. The variable is over 7 equal groups of 50, which represents the difference between Raj's and Fiona's marketing calls. n = 7 x 50 n = (7 x 5) x 10 n = 35 x 10 n = 350 Fiona makes 350 more marketing calls than Raj.
