I had the opportunity to talk about math on a recent episode of “Rad Parenting” hosted by author and self-esteem expert Anea Bogue and comedian and record label owner Joe Sib.
Anea asked me to speak about math in the Common Core era and how parents can best support the mathematical development of their children. You can find the episode here.
In our conversation, I referenced three tips to guide parents in their math conversations with their children. I also mention several resources parents can use to support and guide their efforts. This post recaps those three tips and shares links to resources.
I hope it also starts a math conversation with parents. If you’re a parent and have questions about how best to support your child’s mathematical development, please submit them in the comments on this post. Anea and I hope to have a follow-up conversation on the podcast to answer questions from parents.
Estimation Stations are 10-minute activities for teachers to use to build number sense, promote statistical literacy, and foster purposeful student discourse about estimations in the elementary, middle, and high school classroom. These activities can be an ongoing, weekly instructional routine that teachers can use to invite students to have meaningful and purposeful conversations about their reasoning and work together to refine their accuracy as estimators (individually and as a class).
I have a problem, and I need your help. I love teaching young students about data and statistics. And I enjoy finding ways to make data and statistics matter more to young students. I’m troubled by how we teach students to think about data and statistics, and I have some ideas on how we can […]
Welcome back math geeks!
I love teaching young students about data and statistics. And I enjoy finding ways to make data and statistics matter more to young students. But I’m troubled by two curriculum practices about how we teach students to think about data and statistics, especially at the K-6 level. This post is Part 2. In my first post, I wrote about how data is often represented to students in heavily scaffolded textbook pages that rob students of the opportunity to purposely engage in thinking, wondering, and discourse…and a solution to this practice. (If you missed Part 1, click here.)
In this post, I’ll outline another troubling practice and my attempt to help to teachers work around this obstacle.
Welcome back math geeks! I need your help making a lesson better.
I love Price is Right because many of the games require contestants to make predictions. This often involves estimating prices of products. But sometimes contestants have to make choices of a different nature, and these choices are ripe opportunities to think about probability and expected value. And I love when a fruitful 3-Act Math opportunity presents itself. (I’ve written about one before here.)
The example I want to share now doesn’t seem to fit a 3-Act format. Maybe that’s because it’s not truly a 3-Act Math lesson. But I don’t know what else to call it. I’m curious about your thoughts on how to make it better.
Some questions I’m asking:
Is it too clunky?
What grade levels will find this lesson useful?
What concepts/standards does it best target?
What opportunities did I miss?
What extensions can be made?
I’m inviting your feedback in the comment section. Thanks for helping me get better!
What is Abductive Reasoning?
I’m going to share my new favorite term: abductive reasoning. Maybe you’ve known about it for years and never told me about it. (If that’s the case, you might be a jerk.) Or maybe it’s new to you too. (If that’s the case, let me know because I’m a little embarrassed I haven’t learned about abductive reasoning until recently.)
To recap, deductive reasoning is about making specific conclusions from general statements (like a math proof). Inductive reasoning is about making generalizations about specific observations (like a science experiment).
By comparison, abductive reasoning is about making your best prediction based on incomplete information.
Abductive reasoning?!?!?! Where have you been all my life? Welcome to my lexicon. Have a seat front and center and let’s talk.
(Update: This post is the second in a series about my learning and thinking about argument and how it relates to our work in the math classroom. Click here to read the first post. Click here to read the third.) Welcome back math geeks! Last week, I was preparing for a workshop facilitating the learning […]
I went searching for more knowledge about argument. I fell into a rabbit hole. Help me make sense of this. Do you agree? Disagree? What are your thoughts?
“…there is a difference between mathematical arguments and scientific arguments. The difference is that scientific arguments are always based on evidence, whereas mathematical arguments never are. It is this difference that renders the findings of science provisional and the findings of mathematics eternal…Blurring the distinction between mathematical and scientific arguments leads to a misunderstanding of what science is about.” -NGSS Appendix L
I worked with a team of amazing 2nd grade teachers this week as a part of an ongoing lesson study. They were in the latter chapters of their curriculum where the Measurement and Data content is often stuffed away as an afterthought because they aren’t “Focus Standards.”
And it’s a drag too because there’s so many rich opportunities for meaningful student discourse about data. That is, if it’s done right. Most textbooks suck all the life out of the content. Students need to understand that data tells a story; it has contextual meaning that is both cohesive and incomplete. Students need to learn how to ask questions about data and to learn to identify information gaps. In other words, students need to learn to be active mathematical agents rather than passive mathematical consumers.
We’d like to share with you what we learned about using Numberless Data Problems and crafting an open investigation into bar graphs that is engaging for all students. As always, feedback welcome. Let’s get better together.
Have you seen the amazing visuals over at www.fractiontalks.com? They’re ideal for any teacher looking to get all students, regardless of ability levels, talking about equivalent fractions (4.NF.1), comparing the value of fractions (4.NF.2), and expressing mathematical reasoning. This activity could also work for 3rd grade students that are exploring fraction equivalence (3.NF.3). We used one of images to introduce 1/2 as a benchmark fraction to some 4th grade students. We learned a lot and the students did too! We’d like to share our learning with you.
