• http://www.mathsisfun.com/numbers/casey-runner.html (click on “Flag Race”)

Standard, Expanded, and Expanded Exponential forms

Work with a partner to find a helpful web site on these 3 different ways to write numbers. Share your web site as a comment on this post. And the winners are…

The best link shared by your classmates:
#1) http://www.emints.org/ethemes/resources/S00001385.shtml shared by Garrett — has many excellent links including some of our runners-up…a great resource!

The runners-up:
#2) http://www.aaamath.com/plc31d-placevalue-add.html shared by Brody, Abby, and Tylan — has a good description of place value and expanded form, along with an interactive practice game.
#3) http://www.studyzone.org/testprep/math4/d/hp/standard.htm shared by John, William, and Chase — has an interactive practice game for expanded form.
#4) http://www.icoachmath.com/SiteMap/ExpandedForm.html shared by Ellie, Sadie, Allison, Amanda, Charley, and Kelsie — has an excellent description of standard and expanded forms, but some students seemed to be getting a message that this site may require you to install extra software to view it correctly?
#5) http://mathcentral.uregina.ca/QQ/database/QQ.09.07/h/kent1.html shared by Alex, Ryan, John, Tyler, Carissa, Alex, Molly, Tyler, Dylan, Allison, Amanda, Kenzi, Kaitlynn, Charley, and Kelsie — a very popular site and one of the only ones in this list to explain expanded exponential form!
#6) http://mathforum.org/library/drmath/view/57137.html shared by Michael and Molly — another good explanation of standard and expanded forms.

Welcome!

Welcome to the 2009-2010 school year! I hope you have a great 7th grade year, and I look forward to helping each and every student succeed to his or her highest potential. Keep an eye on this blog for assignments, web links, and more — just use the tabs at the top of the page to navigate the site.

Math Textbook — Online Student Edition

The online student edition of our textbook is an excellent resource! I strongly encourage both parents and students to use the online edition, especially the “Resources” tab. One of the best Resources that accompanies each lesson is the “Personal Tutor”, where real teachers have created videos that walk you through an example problem for each different concept in each lesson. Please make use of the online student edition — the web site is http://www.glencoe.com/ose, and if you’ve lost your access code, just e-mail Mr. Smith to get the code again. Enjoy!
