Math Links for Week Ending April 3rd, 2015

This week we published two similar Easter related activities. The first was a review activity for grade 9 applied math (though it could be used for academic as well). The idea is that students are in groups, they choose plastic eggs that have questions in them and collect points

The second one uses the same template but the topic is a review for analytic geometry in grade 9 academic (though it could also be used in grade 10 applied). Both of these also have versions that have a halloween theme. They have the same questions but you would use them in the fall rather than the spring.

To help students problem solve it is always helpful to give them some strategies to get there. From the Math=Love blog comes some examples of a strategy called SOAR (Show, Organize, Act, Reflect). These are done in the form of posters and prompts shown around the class for reminders. Take a look at all of them here.

I love it when teachers see a math problem in something they do and then take then take the time to collect the data to make it happen. In this case, Michael Fenton took a screen shot of his phone every four minutes for over 2 hours until it was fully charge. And in doing so created a linear data set about phone charging and put it all in the form of a 3Act Task. Well done.

I have always liked Geometer's Sketchpad and I love their blog where they turn sketches into web based interactives. This one is a symbolic representation of a system of equations. They are meant to be solvable by trial and error rather than some more algebraic methods. In fact, the post is trying to show that kids in elementary school can do these types of problems. This would be a great activity for introducing the idea of systems of equations. Make sure you scroll through the pages in the sketch for the ability to make your own problems and for a three term system.

Last week I featured a new website wodb.ca (which one doesn't belong). This week @alexoverwijk shows us how he uses them in his class. Actually what he does is have his students create them. Check out his two blog posts to see how he does it and then has the students rank them.

You might find some things that might be a fun ice breaker on this YouTube channel. Lot's of Math Raps (and some science raps too). Integers, Pi, Calculus and more. Thanks to Free Technology for Teachers for this one.
