'Taught right, every maths pupil could be a Countdown winner' In 1997, James Martin, a quietly unassuming Oxford maths PhD, entered television gameshow folklore with his stunning solution to a maths problem on Countdown. The challenge: make 952 using the numbers 100, 75, 50, 25, 3 and 6. You may use the four standard operations of addition, subtraction, multiplication and division.

Understanding Language This eighth grade (middle school) task provides students opportunities to interpret a situation, represent the variables mathematically, select appropriate mathematical methods, interpret and evaluate the data generated, and communicate their reasoning. Students work with selected formulas to model a situation, interpret given data, make approximations, communicate their reasoning in verbal and written form, and critique solutions developed by others. This task draws on understandings of rate and proportional reasoning (a CCSS focus of grades 6 and 7), geometric measurement and volume (which begins with right rectangular prisms in grade 5, and is extended in grades 6, 7, and 8), and builds toward the high school number and quantity standard of interpreting units consistently in formulas. Making Matchsticks is part of a Formative Assessment Lesson (FAL), which can be downloaded here:

Mr. B's Blog: I Volunteer as Tribute: The Final HSCN The arena set, the districts formed, the Capitol ready. Sounds like the beginning of the Hunger Games, doesn't it? This was the staging for the final HSCN: The Math Hunger Games. To bring you up to speed if you are not familiar with my HSCN, I hosted evenings three times a month where I instructed parents on math and reading. This is explored more in depth in this blog post. Free Printable Math Worksheets (from Western Samoa) Math Games on-line, timed Basic Facts addition, subtraction and multiplication quizzes (Good for any grade - improve basic skills) Math Brain Teaser (Grade 3 and up)

The 5-4-3-2-1 Challenge from Will Shortz and NPR On Sunday morning, Nancy Swank tweeted me a link to a puzzle on NPR's website. This shouldn't come as a surprise because Nancy is the entire reason why NPR spent an entire day in my classroom in 2014. I followed the link and started reading the puzzle. Within about a minute, I knew I HAD to do this puzzle with my students this week. Here's the link to the puzzle from NPR so you can check it out yourself.

NumberFix: RAFT Writing Prompts for Math Writing Across the Curriculum: R.A.F.T. Prompts for Math Class building a writing prompt that challenges students to think deeply about math Classroom writing assignments can feel very unauthentic to our students. Think about it. How to Use Handwriting in Google Documents Earlier this week John Stevens tipped me off to using g(Math) to add handwritten responses to Google Forms. This morning John sent me a direct message on Twitter to tell me that you can now use handwriting in Google Documents through the g(Math) Add-on. John wrote out step-by-step directions with screenshots here. I made a short screencast of the process. That screencast is embedded below.
