3) Use the third set of data to create a line plot graph with an explanation
Wednesday: Complete the Interpreting Data Sheet.
Thursday: Study for Friday’s Graphing Assessment

Finding the Mean

When working with the mean of a set of numbers, then you are wanting the average number. This means that your mean should not be greater than your highest value or lower than your smallest number. Remember, finding the mean has two steps: first step, add all of your numbers together; second step, divide the sum that you found by how many numbers are in your set of data.

For example,

George bought a candy bar for $1.50, twizzlers for $3.50, a coke for $0.75, a toy for $2.50, and a ruler for $0.75. What is the average amount he spent at the store?

Well, we know that average is the same as mean, so my first thing will be to add all of my prices together and the total George spent was $11.00.

The next step is to divide the total by how many numbers are in my set of data and George bought 5 items, so there are 5 numbers in my set of data.

The average amount that George spent at the store can be found by dividing $11 by 5 and the answer is $2.20.

Week 1

This week in math class we will be learning about mean, median, mode, and range. Take some time at home to find opportunities to help your child practice these skills in the real world. Maybe there's a graph in the newspaper, or you could even create a graph at home to use to find this information. Have fun with it and be creative!

Have a great week!

New and Exciting Year!

This year 5th grade will be rotating between teachers for Math, Reading, and Social Studies. I have the pleasure of teaching your child math for the year and I have decided to create this blog to put helpful hints for students to study and practice for classroom skills. I am open to suggestions and comments, so please let me know if a slideshow or video helped you or if I could do something to improve the tool. I look forward to working with each and everyone of you and hope we all have a wonderful school year!
