Division and fractions are not two distinct concepts even if your curriculum separates them into different modules or units.
I recommend moving from equal group problems with whole number solutions to fractional amounts less than a whole within the same context/problem. #iteachmath #mathsky #edusky

There is a push for students to use algorithms because they are "more efficient" and the standards say so.
I argue that it's more important to understand different strategies and flexibly choose which one to use based on the context and the numbers. #iteachmath #mathsky #edusky

In Counting Collections, it's important to allow mathematicians to take the lead. (Even if their strategy seems "inefficient" to you.) This group started with groups of 4 but struggled to count by 4s. I asked, "How can do to make this collection easier to count?" #iteachmath #mathsky #edusky

Launching counting collections in a 3rd grade classroom, we started with choral counting by 10s. Then, students worked with partners to organize and count a collection. Snap photos and use them as image talks with your mathematicians. #iteachmath #mathsky #edusky

Simple modifications to the Eureka curriculum makes it more engaging and accessible for all learners. Consider launching with an image to preview vocabulary and offering number set choices to provide scaffolds and extensions within the same problem. #iteachmath #mathsky #edusky #iteach

The Mathematics Framework is as incredible as it is lengthy. I had the opportunity to lead professional development for this fabulous group of middle school teachers and we dug into Chapters 1 and 7 of the mathematics framework. #iteach #mathsky #edusky #backtoschool

What do you notice?
What do you wonder?
In what context is this true?
I was waiting in line and a young man behind me was wearing this t-shirt. My brain got to mathing as I tried to figure this one out. After solving it I was reminded that context really matters. #iteach #mathsky #edusky

I love connecting read alouds to high-impact math activities. These Are My Rocks by @bethanwoollvin.bsky.social explores what makes a collection. It ends with a call to action, start your own collection. What a beautiful way to launch counting collections! #iteach #mathsky #edusky

Consider image talks inspired by summer destinations. This photo was taken in the shop exiting the Astro Blasters ride at Disneyland.
How can we invite students to share photos from their summer vacations to inspire problem solving contexts?

This question and the data is yielded is really important for us to see. 99 fourth and fifth graders responded to this group's survey.
-What do you notice?
-What do you wonder?
-How can these representations lead to change in how and what we are teaching?

Best way to spend a Saturday morning! We collaborated with UCLA Math Project on a Family Workshop series and it was amazing! Also a great excuse to hang out with some of my favorite educators including @joannahayman.bsky.social and @berkeleyeverett.bsky.social, Leah, Kumi and Stef!

Sometimes the problems in our curricula are too easy for our students. Consider posing open-ended extension questions that engage them in problem-solving using the same context. This keeps everyone immersed in the math and creates space for conferring with learners. #iteachmath #mathsky #edusky

I created this number string to invite 3rd graders to revisit addition, hoping to bring out relational thinking as students solved these problems using mental math strategies. #iteachmath #edusky #mathsky
