A maths investigation is more than completing exercises. It involves thinking, planning, writing, calculating and reflecting. In this lesson, you will learn more about calculation tools that are really useful in maths investigations. It is time to watch a short video explaining how useful Excel is for you today, in next week's group investigation, and in the future.
Written and verbal communication skills are just as important as calculation skills. In this lesson, we focus on spreadsheet skills in Excel so that sourced data can be stored, calculated and interpreted. However, there are other equally important skills and resources, including this video below, which you must watch to complete the activity below.
Activity hint: You may want to clink to this video's link to have them side-by-side.
For homework, follow the instructions in this lesson and prepare a spreadsheet using Excel. This is the exercise the class will do next week however, it provides an opportunity to practice in the meantime:
1. Go to the Bureau of Meteorology (www.bom.gov.au/climate/data) by clicking this link: BOM
2. Select rainfall.
3. Enter your location, then select your town and nearest weather station.
4. Press the "get data" button.
5. Record the daily and monthly totals in your created Excel table.
6. Find the average (mean) daily rainfall by dividing the total rainfall by the number of days.
7. In writing, compare the data with the other months' data.
