Amsco Integrated Algebra I: Numbers as Measurements
 This is a free lesson from our course in Amsco's Integrated Algebra

 This lesson explains the concepts about how to find measurements of object/shapes. The skill building here is backed up from learning in previous sections defining the subsets of the real numbers and use of measuring instrument. The measured values are approximate values as they depend on the accuracy and precision of the measurement. The error in measurement is a mathematical way to show the uncertainty in the measurement.  It is the difference between the result of the measurement and the true value of what you were measuring. You’ll also learn here basics of significant digits, precision/accuracy, ways of expressing error in measurement etc. (More text below video...)

 The Integers The Irrational Numbers
 (Continued from above) The precision of a measurement is determined by the place value of the last significant digit. The accuracy of a measurement is determined by the number of significant digits in the measurement. The video above with help of several examples will help you to find out.

 As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Trigonometry by clicking here. The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
