Welcome to the Blog for Room 217 at Dovercourt Public School. In 2010, back in Room 52, at Alexander Muir/Gladstone Avenue PS, the idea for developing a blog took place. It is a place to begin lessons, open up discussions, and display the learning taking place.
So, why I may never find myself in Room 52 again, it serves as a reminder of a school community that was central to my development as an educator. Thanks for visiting.

Introducing Measurement and Place Value, Math textbook questions, and the rounding of decimals
A former colleague passed on this book to me about the metric system. Eventually, a YouTube video, from the original 1977 film, showed up. Thanks for the book, Kris Janssen!
The book and video serve as interesting introductions to a portion of the Measurement strand of Math, which relates to conversion among measurements in the Metric system.
Often, when I have done this, I have used a chart for converting.
It has been influenced by my Grade 8 teacher, Charlie Binkley, Laydin Bowles and Derek Fereira, both former colleagues. Now, the trick to remembering what the prefixes mean can be found in the expression: King Henry died, drinking chocolate milk. It is true and here is the evidence:
Now, since we are combining some aspects of measurement with the place value chart, I had this bright student named Avery, who made me rethink the original chart and came up with this:
In the homework, you will be asked to do some conversions. You can use the handouts I give you to speed up the process, but you may want to see the conversions in action. I will do some in class and you can refer back to a few YouTube videos, as your guides.
Here are a few Math questions, for the weekend. For some of you who may not want to bring the textbook home, here they are:
In this unit, there will be some rounding going on and this REPETITIVE VIDEO (yes, I know, that is the point) will help you understand how to round decimals.
