Changing Up Popular Warm-Up Routines

As with any task, whether it’s a warm-up or a curricular task, I try to think of ways to get more student engagement, tap a different thinking modality, and just to change things up. WODB has become a common acronym in classrooms for good reasons. (Actually, does it qualify as an acronym like NATO since […]

Common Denominator

I already wrote about dividing fractions here and here. I use the explanation of “dividing by one” to explain why 5/6 divided by 2/3 is the same as 5/6 times 3/2. But when I was asked recently about how the “common denominator” strategy worked, my muted response was, “Because it does.” I didn’t mean to […]

Math Worksheets

I often create worksheets for my students, even though every district-adopted math curriculum we’ve had has worksheets for students. I do this for two reasons: I teach differently — sometimes slightly, sometimes quite a bit — than what the curriculum writing team was thinking. There’s a particular structure/scaffold that reflects how I see the content […]

Jelly Beans or No Jelly Beans

What’s not to love about Would You Rather; I use it with my students and always recommend it as one of the great warm-up routines. This one caught my attention last week. Each entry always includes this statement: Whichever option you choose, justify your reasoning with mathematics. This statement is important, especially the word “mathematics,” because […]

Euclid’s Algorithm

I show my 6th graders this image, pointing out that this picture represents the two numbers 1 and 1 that I’d entered at the top. I then ask them to give me two new numbers — any two positive integers [that are 10 or less, for now] — and the computer will draw a new […]

Solving an Equation with a Fraction

From CPM: The Sutton family took a trip to see the mountains in Rocky Mountain National Park.  Linda and her brother, Lee, kept asking, “Are we there yet?”  At one point, their mother answered, “No, but what I can tell you is that we have driven 100 miles and we are about 2/5 of the way there.” […]

dudamath.com

Ethan Hall, teacher and web entrepreneur from Israel, emailed me this morning asking me to check out his visual patterns generator on dudamath.com. There’s a lot of cool graphing tools other than the VP generator. I’m kinda blown away. Go play! Go do math!

Dividing Fractions

Dividing by one Common denominator It’s completely intentional that we work with the number line and rectangles first. I want my kids to see the answer and that it should […]
