Image of the Week: Give It a Go!

Give It a Go!

Alongside our amazing Look-Think-Talk activities, we offer another routine, Off You Go, and you should give it a go. In Off You Go, you show students an image that represents a concept that they have seen before but where they can still deepen their understanding. This could be a number, shape, pattern, structure, or relationship. You invite them to notice this concept in the image and then you send them off to find example of that concept in their environment that they can bring back to share and discuss.

What’s truly amazing is what happens when students bring back their examples. They might take photos, bring objects, draw sketches, or make lists, but no matter how they collect their examples, the class creates a museum of the many ways the mathematical concept can look. The collections your class assembles can tell you a lot about how they are understanding the concept, and where their thinking is stretching – or needs to be. In fact, my colleagues Geetha and Thomas and I wrote a paper for NCTM’s journal last year about all that students can learn – and all that you can learn about students – from Off You Go.

Look at this week’s Off You Go image. Here we are inviting students to think about the many ways they might see arrays in their world. Arrays are everywhere in the man-made world, taking on every conceivable dimension and proportion, from the windows on a skyscraper to the nubs on a Lego. But most often, students only see arrays as rectangles partitioned into squares, like we shared a few weeks ago in our Array Talks.

When students are repeatedly exposed to the same ways of seeing concepts (like only seeing AB patterns or equilateral triangles), they often don’t understand the diversity within that concept. Some students may at first struggle to see the arrays all around them, but this activity can turn on a mathematical lens for examining tiles on the floor, bins on a shelf, and eyelets on a sneaker, among endless others. When you gather to discuss the arrays that students have found, be sure to discuss the central questions, What is an array? How did you know what to look for? How did you know when you found an array?

We designed the Off You Go routine so that it can be used in at least two ways. You can use this kind of activity as a scavenger hunt in the classroom or school, or try it as an outside walk around your school building or neighborhood. Launching the focus, taking students on the hunt, and then discussing their findings can be an entire rich lesson. Alternatively, you can send students home to look for examples and then hold your class discussion the following day. This is a rich use of homework and widens the possibilities for examples students might collect from their homes, school buses, and neighborhoods. Off you go!

And we invite you to follow us on Twitter! Tweet us the fascinating ideas you students have about our activities or how you’re trying these activities in your space. We can’t wait to hear from you!

To multiplicity, cheers!
