There must be many great sources of lessons that I am missing.Â Please leave me a comment to let me know which websites I need to add to the search engine.

Wow! This is amazing! Thank you so much for doing this. One other great site I’ve found is HungryTeacher.com It has some very cool project ideas, similar to Mathalicious but not as detailed. Keep up the great work!

@EdCamposJR

Thank you Ed. I actually added HungryTeacher.com to the search engine but forgot to add it to the list of sites on this page so thanks for the heads up.

This is so cool and helpful. Thank you so much for this. http://www.gogeometry.com has some challenging geometry problems.

Hi Teresa. Glad it is useful. I searched around gogeometry.com but couldn’t find anything like a problem-based lesson. Could you give me a specific link to a lesson to check out?

Thank you for this search engine. It is very helpful.

What about adding this site? http://ell.stanford.edu/teaching_resources/math

There are only a few tasks here but they focus in on our ELs.

Hi Jennifer. There are some cool lessons there but I don’t know if they would fall under the category of problem based lessons I am aspiring to capture here. Thanks for your idea!

nice work, could you share how you set this up? I like the idea of embedding a search to only look through certain sites.

Also I suggest Dan Meyer’s Graphing Stories, Fawn Nguyen’s blog and the math lab: http://www.themathlab.com/Algebra/linear%20functions%20regressions%20slope/regression%20lessons/barbie%20bungee/barbbungee.htm

Hi Shaun. Check out Google’s Custom Search at https://www.google.com/cse/. That is where you can create your own search engine. It is rather robust but not perfect. For example, it is very challenging to include a site but exclude the blog posts.

Regarding your suggestions, those are all great sites but Graphing Stories and Fawn’s awesome blog are not really within the problem-based learning domain so that is why I haven’t included them. That being said, both of them have been links on the right side of my blog for quite some time so I definitely value them both.

I am having trouble getting the Barbie Bungee jump to load but I will try again another time to check it out.

This is an old post, but I am trying to develop my own 3Acts and have a resource page of them as well.

Hi Bryan. All of your lessons are included since they are posted on 101qs.com. Thanks!

Amazing resource!!! Thank You for creating this search engine!!! đź™‚

Have you checked out the website: http://davidwees.com/

He has some pretty useful articles, especially on strategies for formative assessment.

Full disclosure:

He’s a colleague of mine so I am biased, but I do get a lot out of what he shares and apply to my own work.

Thanks Blue. David is great but I don’t believe he is creating any problem-based lessons. If he is, please list a link to where I can find them.

Thanks Kevin. Can’t believe I forgot Michael. Problem fixed.

Rob, have you come across Tuva yet? Focused on data-based problems for math, science, and many other subjects. You can check it out at tuvalabs.com.

Hi, thanks for the resource!

Would you consider these to be examples of problem-based learning?

Hello. To me the answer is both yes and no. Clearly these are problems that you can base a lesson around. However they are not of the style that we are including in this search engine. If you are interested in examples of elementary tasks of this style, check out Graham Fletcher’s problems here: http://gfletchy.com/3-act-lessons/.

I was so excited to find this resource that I immediately emailed all of the teachers in my department a link to this post. Then, I realized that I had a double block of Algebra I approaching in 15 minutes and I could use this search tool to find a resource that might raise the engagement level for my students. Sure enough…I typed “graphing quadratic equations” into the search box, and numerous resources appeared. I selected the second hit on “Angry Birds”,and it fit seamlessly into my lesson plan. The students asked such great questions and were able to clearly answer questions about the vertex, x-intercepts, and orientation of the quadratic equations that modeled the paths of the angry bird. Of course, then I had to send out another email to my department ranting and raving about my math rush.

Thank you!

Isn’t it cool when it works out! Glad to hear it was useful for you in a tight situation.
