Math Project Grade 5 Unit 2

 

Throughout the year your harvest and transport some trees on your forest. The trees you harvest vary in height but all will be cut into 8-foot logs. Use the information below to show the number of logs you will get from each trees you will cut. Also calculate the total number of logs.

 

Tree Height in Feet Number of Trees Number of Logs
64 6  
112 1  
48 15  
96 4  
80 10  

Total number of Logs _________________

 

Below is a breakdown of grading guidelines

 

Poster is neat and colorful 20 points
The log calculations are displayed and   accurate for each tree and the total number of trees 60 points
11 x 14 poster  used 10 points
Capitalization and punctuation are correct, no spelling or grammatical errors. 10 points

 

Note: 5 points will be taken off for each day it is late.

Division with Decimals          

For adding and subtracting Decimals:

  1. Align the numbers so that the decimals are arranged in a vertical line (one on top of the other)
  2. Perform operation add or subtract

 

For multiplying decimals:

  1. Multiply the  numbers without the decimals
  2. Count the number of digits after the decimal in both factors.
  3. Place the decimal in the product by counting back (right to left) the number of digits counted in step 2.

 

For division of a decimal by a whole number:

  1. Place the decimal point in the quotient directly above the decimal point in the dividend
  2. Divide the numbers

 

Divide decimals when the divisor has a decimal:

  1. Rewrite the divisor as a whole number
  2. Whatever we do to the divisor we do to the dividend
  3. Place the decimal in the quotient
  4. Divide

 

Divide decimals with a remainder

  1. Rewrite the divisor as a whole number
  2. Whatever we do to the divisor we do to the dividend
  3. Place the decimal in the quotient
  4. Divide
  5. If there is a remainder, add a zero to the dividend
  6. Continue dividing
  7. Continue adding a zero and dividing until there is not remainder or  pattern develops
