FINDING TRENDS/INTERPRETING GRAPHS

• What is a trend? Take a few moments and write down your ideas. If we are talking about math, what do you think a trend means in math?

FINDING TRENDS/INTERPRETING GRAPHS

• Put simply, a trend is a pattern in the data.

FINDING TRENDS/INTERPRETING GRAPHS

• Let’s watch the Learn 360 video “Cyberchase: Return to Sensible Flats” to gain a better understanding of how we can spot trends in graphs and how we can use them to make predictions.

• While watching the video answer the questions on the next slide.

Cyberchase: Return to Sensible FlatsVideo Questions

• After constructing the first line graph what trend did they discover? What information were they able to gain?

• What information was gained from the second line graph? How did the pattern help them to gain this information?

• Using the third graph how were they able to predict where the water level would be in the near future?

Responses to Video Questions

• The water level went down steadily after a period of time.

• If it doesn’t rain soon the lake will dry up in about 4 more days. “No rain, no water in the lake”.

• They knew how much the water level had risen in 5 minutes. They then calculated where the water level would be if it continued to rise to the same level every 5 minutes.
