Problem-Solving Strategy: Make a Table

#1 Rosa knits sweaters to sell. Each sweater takes 4 balls of yarn. How many balls of yarn will she use if she makes 23 sweaters? This is a simple multiplication problem. 23 x 4



#2 You will need to use the answer from #1 to help you solve this problem. The first thing you need to find, is the total amount of money Rosa will earn if she sells 23 sweaters for $35. That is 23 x 35. You can use a calculator to find that product. You will see That if Rosa didn't have to buy yar, she would have made a profit of $805. But in the real world, Rosa had to buy yarn. According to problem #1, Rosa needed to buy 92 balls of yarn (shhh yes I know I just told you the answer to number 1), and this problem told us that each ball of yarn cost Rosa $6. That's 92 x 6. That means that Rosa had to spend $552 on yarn. Now you need to take the number she would have made if yarn was free, and subtract the amount she spent at the store to find her earnings. 805 - 552



#3 This is one doozy of a question! Follow me very closely...

Step 1 - Divide the total he made selling portraits by the amount he's selling each one for

180 / 15 You can use a calculator here. He sold 12 portraits.

Step 2 - For every 7 pictures he takes, he has one portrait, so now we need to multiply 12 x 7

That will give you the answer to this problem.



#4 This is a two step problem. If Hannah practices 12 times a day for 5 days, you will need to multiply 12 x 5 to find out how many times total she practices. She practices 60 times in a 5 day week. If she pracitces for 4 weeks, how many times will she practice total? You need to multiply her 60 times by the 4 weeks. 60 x 4



For numbers 5 and 6

Please put the numbers in order from least to greatest. Remember that mode is the number you see the most, median is the middle number, and the outliers are found when you subtract the first two numbers and the last two numbers. If you need a refresher, scroll down to the blog post about median, mode, and outliers.
