5th Grade Math 9.1, Line Plots & Fractional Averages

A line plot is a graph that shows frequency of data along a number line. We can easily see data or compare amounts. An average (also called a mean) is the total sum of number values divided by the number of data. A line plot can help us find an average with data given in fractions. We can find how many times each fraction is recorded on the line plot, find the sub-total amount for each fraction, and then find the total amount for all. Then, we can divide the total by the number of data recorded to find the average. We can use the Order of Operations to find the average of fractional amounts. By organizing the given data into a line plot makes it easier to calculate the average in small steps. This is very helpful when given fractional amounts, but works with decimals and whole numbers too. Remember that fractions are division problems. After we add all the data numbers to get a total and need to divide by the amount of addends to get the average, we can use the dividend as the numerator and the divisor as the denominator. We think of the fraction bar as a division sign. We solve 3 word problems that involve line plots and fractional averages.
