Math Links for Week Ending Apr. 28th, 2017

I don't know if I never noticed this or what but I love this group real world based math problems from @RobertKaplinski. Each one starts out relatively simply but he does a good job with extending some of the ideas and asking good questions. You can either look at the main page for a visual of all the problems or the detailed spreadsheet.

We just published a really simple sorting activity. In this one, you can use these cards to sort students into groups of three by having students match decimal, percent and fraction representations. And as an alternative, if you wanted students could do the same sort as a Desmos card as individuals.

Desmos continues to add to their cannon of neat activities that help kids practice their skills in graphing points. This time its with a context that deals with the classic game Battleship.

Along the same lines as the real world problems above, here is one from @MsALambert at the Critical Math site. It has some great data on the price of food in Nunavut. And there are more math related stories on the site. Check them out.
