### In this session we will discuss:

• Likes and Differences of spreadsheet math and mathematics

• Basic Math Calculations in Excel

• Order of Operations

• Percentages

• Cell References

• Formulas and Functions

• Absolute and Relative

• Solving problems with Excel

• Giving students a real world visual—charts

• Interesting Excel Projects and Ideas

• Summary and conclusion

Spreadsheets may appear to be very complicated and difficult to work with, but actually they can be a great tool to calculate complex calculations as well as repetitive ones and projects that contain large amounts of data.

Using applications such as Microsoft Excel in math classes gives the student a new perspective on how to complete problems and correlate the value of what they are learning to real-world situations by introducing software that is used worldwide in many different types of settings.

Another positive aspect of using Excel in the math class is that it allows students to use technology/computers to complete problems that would ordinarily be completed using a calculator, pencil and paper.

Excel is very easy to get started with; there are only a few basics you need to know when working with entering data in a spreadsheet.

• Spreadsheets consists of rows and columns. Columns are lettered

• beginning with the letter A. Rows are numbered starting with the

• number 1.

• The intersection of a row and column is known as a cell.

• Cells are labeled by taking the column letter and the row number

• and combining to refer to a specific location on the spreadsheet.

• Example: B4 is the cell where Column B and Row 4 intersect.

• Spreadsheets contain only text, values and formulas.

• Types of information found in cells:

• Text—Any non-numeric character (letters, symbols and

• sometimes numbers like social security numbers, grades, ID

• numbers)

• Values—numbers (This does not include commas, hyphens,

• parenthesis)

• Formulas—mathematics

• Functions—formulas coded into Excel that make the math

• simpler to calculate. (SUM, MAX, MEAN, AVERAGE)

• Another interesting fact about spreadsheets is the copy feature. Information in cells can be copied to other locations using either relative means or absolute methods. Relative copying is the default method of copying and in this method cell references are updated to the current location. For example if you have data in C2 and copy it to C3 the formula will automatically adjust itself to C3. This feature works on formulas, text and values.

To copy using the relative method, simply place the cursor (+) on the bottom right edge of the cell and drag if the cells are adjacent to one another. The data is updated immediately as soon as you start to drag.

Sometimes you may not want a cell to be updated when copying it to another location or in a formula. In this case, you will want to use the absolute method of copying data. In this method, the data is copied exactly as it is in the original location. An example of a formula using an absolute copy reference is one where you are calculating a percent of a total, where you want the total to remain the same. To indicate you want a cell or row or column to be absolute, simply place a \$ in front of the letter if you want the column to stay the same or in front of the number if you want the row to stay the same. You can place one in front of each if you wish the entire cell data to remain the same.

Examples: \$A2 – Column will remain A but rows will change.

B\$5 – Column changes but row remains the same.

\$C\$3 – Data will stay the same as it is in C3 wherever it is

copied.

Calculations in Excel are completed much like those done in a math class.

Order of Operations is the same---PEMDAS

Symbols for addition, subtraction, multiplication and division are: +, -, * and /.

Equal sign (=) is entered first to identify to Excel that you are entering a mathematical formula or function. If the = is not the first item in the cell, the formula will be treated as a number and no calculation performed.

Once a formula has been entered the result of the calculation will be shown in the cell in which it was entered.

Examples of simple formulas:

=A1 + B1

=B2*B4

=4*(A2+A5) + 3

Now that we have covered the basics, let’s look at ways to incorporate spreadsheets into math classes to assist in addressing the standards.

Circumference and Area of a Circle

Histograms

Surface Area

Volume

Circle Graphs and Box Plots

Scatterplots and Line Charts

There are many mathematical functions that are built-in to Excel. For a complete list, you can access them at the following link from Microsoft.

Basically, any mathematics can be calculated using a spreadsheet as long as you have the formula and enter it using correct format.

Excel’s charts and graphs features are a great way to address standards and make for a fun way to engage your students!

Here are some types of graphs you can create using Excel:

Column and bar charts—to compare data

Line charts—to illustrate change over time

Pie charts—to illustrate parts of a whole.

Area charts—trends over time, can be 2D or 3D

Scatter plots -- relationships among the numeric values in several data series, or plots two groups of numbers as one series of xy coordinates.
