Estimating & Rounding
MNU 201a
To run the tutorials simply click on the video you wish to play remembering to pause the video when attempting the questions! You should work through the exercises and homework in a squared jotter to keep all your work together. You should mark every section as soon as you finish it and write down your score.
For certain areas you will need a scientific calculator like the casio fx-85GT PLUS.
Good luck! :)
Bronze Level
Ok folks, estimating & rounding first. In our bronze video we start off easy with rounding 2 digit numbers to the nearest 10 and rounding 2 digit numbers to 1 figure of accuracy to quickly estimate an answer.
Video 1: Outcome 1 - Rounding to the nearest 10. Grab a pen and your Rigour jotter. Make sure you try all the questions!
Video 2: Outcome 2 - Rounding to 1 figure of accuracy. This is the final video in this module. After completing the questions, remember to think about your next steps!
