I have posted a new #GETMath task for March 2014. http://bit.ly/1fA0GGf This task is based on Goldbach's Conjecture. I selected this task because there are some similarities to the Sums of Consecutive Numbers task from February. It might be interesting to discuss the ways in which the two problems are alike and how they differ.
This task also has multiple entry points. Students are adding two numbers - which students begin to do in grade 1. For students who might struggle with computation, you can give them a calculator. For students who might not know the prime numbers, you can give them a list of the prime numbers.
For students who need an extension, they can explore finding prime numbers and how one might generate that list. These students could also work to generalize or write a rule for the patterns.
Remember that the purpose of these tasks is not necessarily to focus on content. While mathematical content is important, these tasks lend themselves to the Standards for Mathematical Practice - an essential part of mathematical learning. Use these as an opportunity to engage your students in mathematics and get them excited about mathematics so they are eager to learn additional content!
I hope that you will share your thinking and pictures on Twitter! I look forward to seeing what you have to share!
