Algebraic and Geometric Thinking in the PreK-6 Classroom
Stephen Pape, Johns Hopkins University
Stephen Pape, Johns Hopkins University
This lesson was developed as part of a course titled Algebraic and Geometric Thinking in the PreK-6 Classroom, which was part of a 6-course sequence of courses. The program courses sought to support the development of mathematics content knowledge and pedagogy as well as instructional leadership skills. This program may lead a student to an endorsement as an instructional leader for the PreK-6 context.
The goal of this course is to support PreK-6 content knowledge for teaching related to the following topics: patterns; numbers and operations; measurement, statistics, and probability. Connections of these topics to an integrated approach to curriculum and instruction are emphasized. The course will model the process standards of problem-solving, reasoning and proof, representations, connections, and communication within the context of algebraic and geometric thinking (NCTM, 2000).
By the end of this course, you will be able to:
The Backwards Design+ Framework* supported the conceptualization, design and implementation of this segment of instruction. The remainder of this document is framed around the stages of the BD+ framework.
There were two types of assessments within this lesson, discussion within the online forum and an activity that was ongoing across several sessions. Students were asked to make their mathematical thinking explicit within this latter assignment.
The Discussion for the week asked students to consider an activity in which they engaged (see Activities 2 & 3 below). Students were asked to reflect on these activities and consider how the activities allowed for the following:
The second assessment was a content reflection within their online journal. In these content reflections, students were required to consider the readings and activities within the session and provide evidence of their learning. The instructions for this journal entry included the following:

Each session within this online course began with an overview and session learning objectives as well as a checklist to guide the work that students were required to complete during the session.
The Overview and Objectives were presented in two formats, a slide presentation and a PDF (see Appendix A). The overview provided students with a description of the content of the session. The purpose of this material was to orient the students to the content they will explore during the session.
The objectives outlined the learning that students would engage in or the skills they would be able to do by the end of the session.
In addition, this material for this session included the NCTM standards for Algebra (https://www.nctm.org/Standards-and -Positions/Principles-and-Standards/Algebra/).

As you continue to explore algebraic thinking, you are encouraged to explore the notion of a connected function machine, which is simply a single function that takes an input, runs it through the network inside, and produces an output.
As you complete this online interactive activity, you will control a network of function machines by controlling the input and the operation performed by each function machine.
As you complete a series of activities exploring connected function machines, draw a function machine network or print out a copy of the function machine network provided on the website to help you answer Problems C1 - C5.
In order to access this simulation, you will need to navigate to E-reserves and select Session 3, Part C: Function Machines from the Session 3 list. Because this is a Flash-based simulation, you will need to open it in Foxfire or Edge, and activate Flash.

The next segment of the session asked students to engage with a mathematics task. This established the mathematics goals for the session to focus learning by providing students an initial experience with the mathematics content. This engagement with a mathematics investigation as an anticipatory activity began participants’ thinking about the mathematics content they would explore during the session. It was also intended to reveal their initial mathematical thinking at an adult level.

Overview
Although algebra is a word that has not commonly been heard in elementary classrooms, the mathematical investigations and conversations of students in these grades frequently include elements of algebraic reasoning. Algebraic reasoning involves students forming generalizations from their experiences with numbers and computation and formalizing their ideas with the use of a symbol system and exploring the concepts of patterns and functions (Van De Walle, Karp, and Bay-Williams, 2018). To develop algebraic thinking, it is important for every teacher to provide students with multiple opportunities to use algebraic concepts to investigate situations and solve mathematical and real-world problems using numbers, words, and symbols. The more time students spend developing meaning for the arithmetic operations of addition, subtraction, multiplication, and division the better sense of the uses of mathematical concepts they have leading to greater success in algebraic thinking and functions in the upper grades.

During each session, the faculty provided an overview of the content with which students would engage. This overview was in the form of a brief written description of the content and a video presentation. The overview for each segment of the session was intended to further orient the students to the content of this segment (e.g., Presentation, Reading, Activities).

This week’s readings will be focused on children’s understanding of patterns, relations, and functions. You will have an opportunity to concentrate on your grade level. These videos will build upon the instructor’s weekly announcement where examples from your online weekly journals will be shared as a way to continue to support your development of algebraic thinking.

Activity 1: Orange Problem
Directions
Solve the following (remember to capture all your thinking/work – this should be uploaded into your weekly online journal).
A grocer was asked how many oranges he had sold that day. He replied: “My first customer said I'll buy half your oranges and half an orange more.” He then said, “My second customer said the same thing… I'll buy half your oranges and half an orange more.” Then he stated, “My third customers said the same thing... I'll buy half your oranges and half an orange more.” Finally, he stated, “When I had filled all three orders I was sold out and I did not have to cut a single orange all day." How many oranges had the grocer sold in all?
Building from the scenario above, answer the following questions:

Following engagement with the mathematics activities, students were required to engage in a discussion about their experience. This discussion was an initial reflection on the activities, their learning within the activities, and focused on the potential for these activities to support their students to learn important mathematics content. Throughout the remainder of the session, students were to come back to this discussion forum to continue the conversation with their colleagues and instructor.

This activity was an ongoing reflection that students were to complete after each session (see Appendix B). In this reflection students were to demonstrate their content understanding and draw connections to their classroom practice. This activity could be completed in either written or video format. Students were provided a research-based description of an academic reflection with the intended purpose of supporting content acquisition, problem solving, and application. The learning objectives aligned with the assignment are clearly described in the assignment description (see Appendix B), and a rubric is provided to guide student completion of the assignment and instructor assessment of the students’ work.

Students in this course were required to construct an ongoing content analysis (see Appendix C for assignment description). This assignment required students to consider the mathematics content, historical perspectives, the interconnectedness of the concepts revealing how they built upon one another, and a reflection on their learning process. They were also required to provide evidence of the connections to the NCTM Principles for School Mathematics, the Standards of Mathematical Practice, and the InTASC standards. Finally, this assignment required them to plan an activity they would enact with the school students attending to the diversity within their context.
The assignment description page included a clear alignment to the course and program learning objectives as well as a rubric to guide students’ completion of the assignment and instructor assessment of the students’ work.
