Thinking About the Operation and Algebraic Thinking

Operation and Algebraic Thinking is a critical domain in elementary mathematics. It forms the foundation for advanced mathematical concepts as students progress through their education.

Let’s explore the significance of Operations and Algebraic Thinking for grades 2,3, and 4, share a sample lesson plan, and provide resources such as worksheets, patterns, representations, concepts, and examples to assist teachers and parents in promoting mathematical success.

Understanding the Domain

Operation and Algebraic Thinking primarily focuses on developing students’ fluency in addition, subtraction, multiplication, and division.

However, it goes beyond basic calculations and encompasses core concepts such as understanding patterns, creating and interpreting representations, and applying logical reasoning to solve problems.

Lesson Plan: Introduction to Patterns

Grade Level: 3rd Grade

Objective: Students will be able to identify and create patterns using numbers and shapes.

1. Warm-up Activity: Begin the lesson by engaging students in a pattern hunt around the classroom. Encourage students to identify patterns in the environment, such as the arrangement of books on a shelf or the pattern in a tile floor. Discuss their findings as a class.
2. Introduce Number Patterns: Display a pattern on the board using numbers, such as 2, 4, 6, 8, __. Ask students to identify the pattern and predict the next number. Discuss the concept of a rule or pattern in number sequences.
3. Create Number Patterns: Provide students with a worksheet that contains incomplete number patterns. Students should fill in the missing numbers to complete each pattern. Allow students to work independently or in pairs.
4. Identify Shape Patterns: Show students a sequence of shapes (e.g., circle, square, triangle, __) and ask them to identify the pattern and predict the next shape. Discuss the concept of a rule or pattern in shape sequences.
5. Create Shape Patterns: Distribute a worksheet that contains incomplete shape patterns. Students must complete each pattern by drawing the missing shape. Encourage creativity and exploration of different shapes.
6. Wrap-up Discussion: Lead a class discussion to review the various number and shape patterns created. Ask students to share their strategies for identifying and completing patterns.

Additional Resources

To reinforce lesson concepts and provide practice opportunities, the following resources can be utilized:

• Worksheets: Provide students with worksheets containing various number and shape patterns to practice identification and completion.
• Patterns Representations: Use manipulatives such as pattern blocks, cubes, or tiles to create physical representations of patterns for students to explore and comprehend.
• Online Tools: Explore online platforms and apps that offer interactive pattern games and activities, allowing students to engage in a gamified learning experience.

Using Technology to Understand Math

If you are using the Common Core State Standards, you are already familiar with the Operations and Algebraic Thinking strand listed in the Math CCSS.  As I was thinking about things I would use in the class for this strand, I remembered a wonderful website I have used with students in the past and wanted to make sure I passed it along to you all!

If you have never used the Thinking Blocks website, I highly suggest checking it out!  It correlates with CCSS standards for grades 1-6 and is completely free!

I originally found this site after learning about Singapore Math and modeling word problems.  This site seemed to exactly match the big ideas I learned from that training. 

Personally, I had to really re-train my own thought processes to understand how to model the problems myself, but the students understood it right away and showed me how to do them! 

That just shows that the students “got it” immediately and it clicked.  They were so excited about this site and wanted to do all the problems right then and there.  (That should be a victory flag moment all on its own!)

I encourage you to stop by and see Thinking Blocks for yourself – especially if you are looking for new ways to make the OA, NF, and/or RP standards stick.

I also have some additional ideas for sponge activity time fillers for your math time for my 4th grade friends!

Common Core Skill Sharpeners:  Grade 4 Operations and Algebraic Thinking!

62 pages in all, this packed activity set can be used for centers, intervention resources, or as a filler activity for those early finishers. Make sure to have them on hand to use in the case of emergency sub plans. You will never have to hear “I don’t know what to do” again!

Just grab the simple materials listed (hard goods such as the books are not included – only digital files), pop them into an accordion file folder along with the directions and blackline masters included in the set, and place them in a spot on a shelf in your classroom that is easily accessible to students.

If they have two minutes or 20, they can work on the skills in the set to reinforce those so important Common Core State Standards all day long.

This set includes six-different literature-based learning, hands-on, math journaling, and open-ended problem solving activities! Perfect for your early finishers – or as a reward for those who need an extra incentive!

Find all available Common Core Skill Sharpeners located HERE.
