How do we improve retention in the secondary school math classroom?

Dan Meyer’s 3 Act Math Problems

Click here to see the list with links to many 3 act math problems.

Description: Part of conceptually understanding a topic in math is being able to apply algorithms and procedures to open ended problems. Dan Meyer is a leader in the field of giving students well though-out, open ended problems to promote conceptual understanding. He uses the concept of “3 Acts” to a problem meaning progressively more specific questions as you go through each act and then other teachers can add questions to the “sequel.” The link above will take you to a google doc that Dan Meyer has created that lists links to many of these “3 Act” problems.

Gizmos

Click here to go to the Gizmos website.

Description: Gizmos says they are “The world’s largest library of math and science simulations.” Gizmos is free with a sign up required, but with that account you get access to all of the simulations the website has to offer. One interesting part about this site is you can find simulations based on what province’s curriculum you are in and what class and grade level you are teaching.

Didax: Virtual Manipulatives

Click here to go to the Didax website.

Description: Didax is a website that has many different free virtual manipulatives that can be used in the math classroom including Algebra Tiles which have been proven to improve memory retention and a better conceptual understanding (See Research section). There are many other free virtual manipulatives including fraction tiles, geoboards, and prime factor tiles. Along with these manipulatives are “how to” videos that explain how to use each virtual manipulative and specific activities for the classroom that use each virtual manipulative.
