Authentic Lessons for 21st Century Learning

Thinking Outside the Equation for High School Math Teachers: Learning Activity 2 of 6 - Spatial Reasoning

Lindsay Hawkins, Cacey Wells

Essential Questions

  • How does one engage in non-routine mathematical tasks?

  • How can non-routine tasks promote spatial reasoning?

Learning Goals

  • Develop participants’ understanding of authentic researched-based mathematical practices.

  • Explore and develop non-routine math tasks that correlate to appropriate grade levels.

  • Demonstrate the incorporation of strategies and instructional tasks that foster a growth-mindset for flexible mathematics.

  • Deepen participants’ understanding of number sense and mathematical concepts through interactive, non-routine tasks, and student inquiry.

Materials List

  • Droodles

  • 8.5 by 11 copy paper cut to 8.5 by 8.5

  • Pen/Pencil

  • Scratch Paper

Engage

To kick things off, participants will engage in a short activity involving Droodles. These are pictures with interesting shapes on them, many of which contain interesting shapes and lines.

Set out the Droodle Pictures on a table. Ask participants to come up to the table to choose a Droodle that they like, find interesting, or that "speaks to them."

Upon returning to their tables, ask participants to make mental notes about what they see in the Droodle and to rationalize why they chose it.

Depending on the size of your PD, ask participants to share why they chose their Droodle to the whole group (less than 15 participants) or to their table-mates (15 or more participants).

After participants have shared, ask them to discuss at their groups the geometry they see within the Droodle.

Part 1: Constructing and Analyzing One Star Building Unit

Using the Unit Origami Handout, follow the steps on pages 586-587. This will allow you to construct one star building unit.

After construction, unfold what you've created. Yes, unfold it after all your hard work...

Answer the following questions and discuss with your tablemates:

  • What do you notice?

  • What geometric shapes and/or structures are present?

  • What symmetries do you see?

  • How many parallel lines exist? Transversals? Perpendicular lines?

Part 2: Constructing a CubePart 2: Constructing a Cube

Constructing a cube is simply a puzzle. Once you have either reassembled your deconstructed unit or rebuild a new one, you can build a cube with a little more work.

Make six star building units in the exact same fashion as in part 1

Begin fitting the units together. This takes some time and practice, but the goal is to use the flaps and "arms" from the star building unit to fit together to form a cube.

Explain

Still working in groups, pose the following question to participants in a Think-Pair-Share: What did you learn/notice about the activity?

Think: Ask participants to think about the question in terms of mathematical content and application to their classrooms for about 1 minute.

Pair: Have participants share with one person within their group. Give each participant about 2 minutes to share.

Share: Solicit a handful of responses from those willing to share with the whole group. Respond to each participant or open the floor to others to share their thinking.

Extend

Metacognitive Reflection: Ask participants to take a few minutes to silently reflect and write about TWO of the following questions:

  • Thinking about growth mindset in your practice, what things would you need to change and how would you change them in order to implement this task?

  • What mathematics are students being engaged in?

  • In what ways was this task low floor/high ceiling?What was the task?

  • How is it meaningful to students?

  • How can you implement this into your class with your students?

  • What standards were addressed within this activity for my grade level?

  • Where do you see students' potentially growing in their spatial reasoning skills?

Evaluate

This particular PD did not have an evaluate section for this learning activity. However, feel free to use the following instructional strategy as a way to evaluate participant learning:

3-2-1

What are three things you are thinking about now that you have finished this learning activity?

What are two things you could try in your classroom?

What is one question or concern you have?

Research Rationale

Mathematics education has a rich and complex history, shaped largely by major educational reform initiatives. At the turn of the twentieth century, mathematics classrooms were often seen as learning laboratories which incorporated hands-on lessons and inquiry-based learning scenarios similar to what one might see in a science lab (Kilpatrick, 2014). Influential educators, like Dewey, were at the forefront, implementing constructivist pedagogies hinged on students constructing knowledge and making meaning for themselves (Dewey, 1950; Kilpatrick, 2014; Schiro,2013). These pedagogies were in stark contrast to traditional, lecture-based disseminations of information during this period in history. Throughout the decades following, political agendas and industrial demands in the US aimed at producing more mathematicians and scientists, along with international competition to be the best in mathematics, have retrograded pedagogical strategies to less progressive eras in history. Major educational reforms driven by federal initiatives like “A Nation at Risk,” “No Child Left Behind,” and “Race to the Top” have placed major emphasis on efficiency in mathematics education, thus promoting a factory model for schools (Kilpatrick, 2014; Schiro, 2013; Teitelbaum, 2014). As a result, teaching and learning today looks very similar to how it did in the nineteenth century, but with more emphasis on holding teachers accountable to teaching prescribed standards. So, it is no surprise then that the US has consistently fallen behind other countries in terms of mathematics achievement (Kilpatrick, 2014; Teitelbaum, 2014). Despite pushes for efficiency in mathematics education, educators like Boaler (2016) have been essential to the survival of progressive mathematics education. She and others view mathematics learning as less of a gift and more of a learned discipline. She has championed for pushes to foster growth mindset in mathematics teaching and learning, which is where this professional development is rooted. Boaler (2015) shares that students’ mindset about mathematics greatly shapes their beliefs about themselves as learners and impacts their confidence in constructing mathematical knowledge. There exist two types of mindsets: fixed and growth. People who have fixed mindsets about mathematics tend to view themselves as being able to reach a limit for how much they can understand. On the other hand, those who have a growth mindset are more inclined to persevere through mistakes and tend to have positive beliefs about themselves as mathematics learners as they essentially have endless potential to learn (Boaler, 2015; Yeager & Dweck, 2012). Furthermore, mindset tends to be infectious. Students whose teacher has a growth mindset about mathematics were shown to have higher achievements and better mathematical performance, even those students who were tracked into lower-level courses (Dweck, 2010).
