Today we discussed how to solve addition and subtraction word problems. Homework is addition and subtraction problem solving worksheets.
Seventh Grade
Math - Mean, Median, Mode, and Range. If you forgot your notes, here is how to solve each:
Mean - This is the same as the average (mean ole average!). Add the numbers and divide by the number of numbers. Round to the nearest whole number or nearest cent.
Median - Write the numbers in order from least to greatest. The median is the middle number. If there is an even number of numbers, the median is the average of the middle two numbers. For example:
5, 6, 6, 7, 9, 13, 14, 14, 15, 16
In the above list, the 9 and 13 are the middle two numbers. Add them together - 22 - and divide by 2. The median is 11.
Mode - The mode is the number that occurs most often. There can be more than one mode if more than one number occurs the same number of times. Sometimes there isn't a mode if there are no numbers that occur more than any others.
Range - This is the difference between the greatest and the smallest number.
Geography - There is a test tomorrow over Chapter 3. Be sure to study! The essay will be to write about the similarities and the differences between a direct democracy and a representative government.
