Google My Maps in Math

When one thinks of incorporating Google Maps into their curriculum, the first thought is Social Studies. While that’s quite natural, I have incorporated Maps into most subjects. My latest brainstorm came when I was teaching adding and subtracting fractions. Yup, you read that right, I have students adding and subtracting fractions using Google Maps.

One simple option is to plot a point and place a real-world problem in the description box. Good start, but what if the students used distances to find the sum or difference?

screen-shot-2017-02-06-at-6-23-22-pm I created this map of our town and included lines (using the draw line tool) to various locations in our town. This is where it got #eduawesome! The distance (which is displayed once the line is chosen) is shown in decimals! This means they have to convert the decimal to a fraction or mixed number, find the common denominator, and THEN add or subtract! And just to make life a bit more fun, I wasn’t too precise on all my lines. This means they also had to ROUND to the nearest hundredth and in some cases simplify!

For example:

Find the difference between Route A and Route B.
Route A – From school to a local Mobile Home Park (0.753 mi)
Route B – Keefer’s Inn to the high school (0.599 mi)

In this case, Route A was rounded to the nearest hundredth (0.75) while Route B was rounded to the nearest tenth (0.6). Then students had to convert this to a fraction and simplify. Route A = 75/100 = 3/4. Route B = 6/10 = 3/5.

Finally, the students were tasked with finding the difference. There were a lot of steps in there, but it was so much more fun than writing out and solving problems in the workbook. This was more in depth than any workbook I’ve seen, more fun, easy to create, and used a variety of acquired skills. I will be doing more things like this in the future.
