Narrowing It Down: Interval Estimates for Multiplying Mixed Numbers
Avrila at Math With Avrila
Average rating:4.9Number of reviews:(7)
In this one-time class, learners will learn to estimate products of mixed numbers and apply their skills to word problems.
Class experience
Learners will find out about and use estimation methods for products of mixed numbers in the form of intervals, such as "the answer is between 15 and 24," and use this method to work mixed number application problems on topics like baking and gardening. The method will be represented visually, using rectangles, as well as in the form of a rounding-based algorithm. If learners are interested in exact answers, as class wraps up Avrila will demonstrate extending the rectangular representation...
Learners will become familiar with overestimates, underestimates, and interval estimates. Learners will estimate products of mixed numbers using rectangles. Learners will estimate products of mixed numbers using rounding. Learners will use estimates for products of mixed numbers in application problems. Learners who are interested will become familiar with exact methods for multiplying mixed numbers using rectangles.
Something to write on and something to write with. Graph paper would be handy for drawing rectangles on — printed out or made by drawing vertical lines onto lined notebook paper will be good enough. If you can't get graph paper, that's OK; just label your rectangles carefully. Parents can also let learners use any other tools they usually would use for multiplication, like a chart, calculator, or counters.
In addition to the Outschool classroom, this class uses:
TeacherMade is a site designed for school use which allows learners to access worksheets, tutorials, and practice problems. If they wish, such as for added privacy, learners can sign in using a nickname or pseudonym. Explain Everything is a shared whiteboard, similar to Google Jamboard but more flexible. Learners do not need an account and can access the board to write on it through a link. Learners who do not specifically want to write on the board don’t need to access Explain Everything at all – I will share the screen in Zoom and they can watch.
