Sixth grade math covers many different topics, including addition, subtraction, multiplication and division of decimals and fractions, percentages, negative numbers, and graphing on a coordinate plane. The following problems are examples of word problems a sixth grader might encounter.
This problem involves adding and subtracting decimals:
"Helen is raising money for a class trip. She receives donations of $33.50, $10.00, $14.99, $28.00 and $0.75. How much money has Helen raised? How much more does she need to raise if her goal is $100?"
To solve this problem, first add the donations. The total is $87.24. Then, subtract this total from $100. The result is $12.76 remaining for Helen to raise.
This word problem involves percentages:
"Grace wants to buy a book that costs $9.50. There is an additional sales tax of 5%. Is $10 enough money? If not, how much more money will Grace need?"
To solve this problem, first find the value of the sales tax. It is $0.475 (which rounds to $0.48). Then, add the tax to the book price. The total is $9.98, so $10 is enough money for Grace to buy the book.
This word problem involves negative numbers:
"The warmest temperature ever recorded on Earth is 134° Fahrenheit, and the coldest temperature ever recorded is -128° Fahrenheit. What is the difference between these two temperatures?"
To solve this problem, subtract -128 from 134. The result, 262, is the difference between the two temperatures.
