Explain the Remainder

Explain the Remainder

Suppose you have 134 stamps in your collection.  You want to display them on 5 pages of an album with about the same number of stamps on each page.  About how many stamps should go on each page?

To solve, first we have to estimate. There are many different estimates. 150/5, 135/5 and even 130/5. Any of these estimates are reasonable. To check your work you can do the real division which results in 26 r 4. This meant that 4 of the 5 pages would have 27 stamps and one page would have 26 stamps.

This week, please write your own word problem that

• uses division to solve
• requires estimation
• requires the actual answer
• results in a remainder
• requires an explanation of that remainder

Make sure you write the problem and do all the work!

Greetings Math Class

Mrs Lynch is redoing the floors in the bedrooms of her house. She has one bedroom that is 9.5 ft by 10.4 ft. She also has 3 bedrooms that are 8.4 ft by 9.35 ft. The amount of flooring is determined by finding the area of all four rooms. Write an equation to show the problem that needs to be solved, use a variable that helps tell the story. Explain your variable. How much flooring does she need?

(9.5 * 10.4) + 3(8.4 * 9.35) = s 

s = square feet of flooring

(9.5 * 10.4) + 3(8.4 * 9.35) = s 

     98.8       +  3   (78.54)    = s

     98.8       +      235.62     = s

              334.42                  = s  

             334.42 sq. ft

Your turn. Use the comment box to write your own word problem similar to the one above. Make sure to ask the same questions and include the answers using the same format. Type this ahead of time in a document. notes, etc. Then copy and paste it into the comment box. 

Special notes: 

• * means to multiply
• parenthesis next to a number means to multiply
  3(4) = 3*4=12
  or 3(9-4) = 3*5=15
• Do not forget the order of operations

Can You Model Your Work?

Write a real world problem that uses subtraction and can be solved drawing a picture and using two different equations. Show your pictures if you can, write both equations and write your answer.
