Unit: Shape Explorers: 2-D Shapes

Lesson 1 of 10

Title: Let's Meet Our Shapes

---

Standards Alignment

• Georgia Standards of Excellence for Mathematics (Grade 3):

  • MGSE3.G.1: Understand that shapes in different categories may share attributes and that the shared attributes can define a larger category.
  • MGSE3.G.2: Partition shapes into parts with equal areas and express the area of each part as a unit fraction of the whole. (Introductory awareness connection)

• Common Core State Standards for Mathematics (Grade K) – as foundation:

  • K.G.1: Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.
  • K.G.2: Correctly name shapes regardless of their orientations or overall size.

Note: Although the lesson targets 3rd graders, initial understanding and revisiting foundational shape naming sets strong conceptual groundwork for deeper 3rd-grade geometric reasoning.

Learning Objectives: (Using "I can" statements)

• I can identify and name circles, squares, triangles, and rectangles.
• I can recognize shapes in different orientations and sizes.
• I can describe attributes of these shapes (e.g., number of sides, corners).
• I can use shape vocabulary correctly when talking about objects around me.

---

Success Criteria

• Students can confidently name and point to circles, squares, triangles, and rectangles in pictures and the classroom environment.
• Students demonstrate understanding by describing basic attributes of these shapes during discussions or games.
• Students actively participate in the shape identification game with minimal prompting.
• Students show comprehension through informal formative assessment by correctly identifying shapes on flashcards and storybook images.

---

Language Function

• Describing
• Identifying
• Comparing attributes
• Using spatial/location words (beside, above, below)

---

Content Vocabulary

• Circle
• Square
• Triangle
• Rectangle
• Sides
• Corners (vertices)
• Shapes
• Attributes

---

Syntax and Discourse Features

• Use of descriptive sentences: "This is a triangle because it has three sides."
• Comparative language: "A square has four equal sides, but a rectangle has four sides with two longer and two shorter."
• Language frames: "I see a ___ because it has __ sides."

---

Materials and Resources

• Shape flashcards (circles, squares, triangles, rectangles)
• Large poster with shapes shown in various orientations and sizes
• Storybook focusing on shapes (with visuals) — teacher-read aloud (e.g., “The Shape of Things” or a custom simplified story linking shapes to everyday objects)
• Whiteboard and markers
• Shape sorting mats or trays
• Dyslexia-friendly printed storybook or handout versions (simple font, large spacing, sans-serif typeface)
• Visual aids with color coding for different shapes
• Shape identification game cards
• Smartboard/tablet for interactive activities (if available)

---

Differentiation Strategies

• Visual Learners: Use colorful shape cards, visual storybook, and shape posters.
• Auditory Learners: Interactive story read aloud with repetition and chants for shape names.
• Kinesthetic Learners: Shape identification game with movement (students physically place shape cards on mats).
• English Language Learners (ELL): Use picture-word matching and sentence frames; pair ELL students with peer buddies for language support.
• Students with Dyslexia: Provide dyslexia-friendly reading sheets and audio version of the storybook. Use multi-sensory approaches (touch and trace shapes).
• Advanced Learners: Challenge with shape attribute sorting, identify examples of shapes in complex pictures, or drawing new shapes with more sides.

---

Extension Activities for Advanced Learners

• Create composite shapes by combining two or more basic shapes and describe the new shape created.
• Write a short descriptive paragraph about a favorite shape and its attributes.
• Explore area concepts by coloring parts of a shape, connecting to later MGSE3.G.2.
• Introduce irregular shapes and ask students to compare them with basic shapes.

Lesson Layout and Instructional Time Breakdown

1. Introduction / Hook — 10 minutes

• Begin with a lively read-aloud of the shape storybook focusing on circles, squares, triangles, and rectangles.
• Use expressive and clear language, pausing to point out shapes in the illustrations.
• Introduce vocabulary and have students repeat shape names in chorus.

2. Direct Instruction & Guided Practice — 15 minutes

• Display shape flashcards one at a time; ask “What shape is this?”
• Use sentence frames: “This is a ___ because it has ___ sides.”
• Discuss attributes of each shape briefly (number of sides and corners).
• Show shapes in different orientations and sizes on the poster. Ask students to identify and describe.
• Use language function prompts to encourage full sentence responses.

3. Shape Identification Game — 20 minutes

• Divide students into small groups (4-5 students).
• Distribute shape cards and sorting mats.
• Call out the name of a shape; students find, hold up, or place the shape on the mat correctly.
• Incorporate movement by asking students to “stand up if you see a triangle” or “sit down if you have a circle.”
• Monitor and informally assess based on accuracy and participation.

4. Independent Practice — 10 minutes

• Students complete a simple worksheet or drawing activity where they identify basic shapes in pictures or draw and label shapes themselves.
• Provide scaffolds and sentence starters for writing.
• Circulate to provide individualized support and check for understanding.

5. Closure / Reflection — 5 minutes

• Recap the day's learning with students sharing “I can” statements aloud.
• Quick quiz: Ask students to name or point to shapes you flash quickly.
• Reinforce vocabulary and congratulate students on their shape knowledge.

---

Assessment

• Informal and formative through observation during the shape identification game and group discussions.
• Review completed worksheets/drawings for shape accuracy.
• Use anecdotal notes for student vocabulary and sentence usage.
• Exit ticket: student names at least two shapes learned today and describes one attribute orally or in writing.

---

Notes on Language Acquisition & ELL Supports

• Use visual aids and gestures consistently.
• Repeat key vocabulary often and provide multiple examples.
• Encourage peer collaboration and scaffold conversations with sentence frames.
• Modify language demands during independent practice as needed.
