Common Core State Standards Alignment

Mathematics: Geometry
CCSS.MATH.CONTENT.3.G.A.1
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals).

CCSS.MATH.CONTENT.3.G.A.2
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole.

Learning Objectives

• I can identify and name 2-D shapes including triangles, squares, rectangles, circles, rhombuses, trapezoids, and hexagons.
• I can recognize attributes of shapes based on the number of sides and corners.
• I can demonstrate knowledge of 2-D shapes by actively participating in a shape bingo game.

---

Success Criteria

• Students correctly identify shapes when shown a picture or when hearing the shape’s name.
• Students explain one attribute of a 2-D shape verbally during game play.
• Students actively engage and respond during the bingo game, showing reinforcement of their understanding.

---

Language Function (Focus for ELLs)

• Naming and describing shapes (e.g., “This is a rectangle. It has 4 sides.”)
• Listening comprehension and following directions during the game
• Using simple sentences with shape vocabulary

---

Content Vocabulary

• Triangle
• Square
• Rectangle
• Circle
• Rhombus
• Trapezoid
• Hexagon
• Side
• Corner (Vertex)

---

Syntax & Discourse Patterns

• “This shape is a ___.”
• “It has ___ sides.”
• “I see a ___.”
• Following blurted-out shape names in a game setting
• Asking and answering questions about shapes

---

Materials and Resources

• 25 Shape bingo cards with a variety of 2-D shapes (each unique)
• Shape calling cards with both the shape image and name
• Dry erase boards and markers for students (optional for independent responses)
• Dyslexia-friendly printed shape vocabulary cards (with clear font, large spacing)
• Visual aids: poster or projection of 2-D shapes and their names
• Audio recordings of shape names for auditory reinforcement (for multisensory learners)

---

Differentiation Strategies

• For ELLs: Use picture cards and gestures; pre-teach vocabulary before game; provide sentence frames (“I see a ___.”)
• For Dyslexic learners: Use dyslexia-friendly fonts for all printed materials; allow oral responses; provide additional visual support
• For Kinesthetic learners: Allow movement to mark their bingo cards; use hand motions for shapes (e.g., tracing shapes in the air)
• For Advanced Learners: Challenge with asking them to describe attributes or compare two shapes after bingo; extension activity included

---

Multiple Intelligences Addressed

• Visual-Spatial: Shape cards and posters
• Bodily-Kinesthetic: Game participation, marking cards
• Verbal-Linguistic: Speaking and listening during the bingo calls
• Musical-Rhythmic (optional): Use rhythmic chanting of shape names for auditory learning

Lesson Layout and Timing

Time	Activity	Description & Notes
0–5 mins	Introduction and Objective Review	Teacher greets students and reminds them of the unit focus. Uses “I can” statements: “I can name and describe 2-D shapes.” Brief review of shapes using a poster and student volunteers to name and share attributes.
5–10 mins	Vocabulary Warm-Up	Show dyslexia-friendly cards with shapes and their names, say names aloud, and have students echo. Use gestures for each shape (e.g., fingers counting sides).
10–12 mins	Rules and Setup of Bingo	Explain game rules clearly and demonstrate the bingo card layout. Emphasize listening carefully to shape names and looking for the shape visually on the card.
12–35 mins	Shape Bingo Game	Teacher calls out shape names (using audio recording or voice). Students mark their cards silently. Periodically, ask students to say one fact about a shape to reinforce vocabulary (e.g., “What do you know about the triangle?”). Rotate roles to keep engagement.
35–40 mins	Guided Practice/Verbal Review	After game, ask students to verbally share a favorite shape and one thing about it using sentence frames. Possible partner-share or think-pair-share to support language practice.
40–43 mins	Independent Practice	Students select one shape from the bingo cards and draw it on dry erase boards or paper, labeling it with its name and one attribute (e.g., 4 sides). Teacher circulates to provide feedback.
43–45 mins	Closure and Assessment	Recap “What have we learned about shapes?” Prompt students to answer orally. Participation in the bingo game and verbal responses serve as formative assessment. Praise all efforts and preview upcoming lesson.

---

Assessment

• Formative assessment through observation during bingo game participation.
• Verbal responses during guided practice and closure provide insight into comprehension.
• Teacher notes on students needing extra support or advanced challenges.

---

Extension Activities for Advanced Learners

• Create “My Shape” posters where students draw multiple shapes and write two properties of each.
• Challenge to find objects around the classroom or home that correspond to specific shapes and present to the class.
• Encourage explaining why certain shapes are used in different contexts (e.g., stop sign = octagon, wheels = circle).

---

Dyslexia-Friendly Reading Options

• Use fonts like OpenDyslexic for vocabulary cards and instructions.
• High contrast color schemes (black text on white or light yellow background).
• Provide oral versions of reading materials and allow students to listen to shape names.
• Break instructions into short, manageable chunks with visuals.

---

Notes for Educators

• Engage students with movement and visuals to cater to diverse learning styles.
• Use positive reinforcement often to build confidence, especially for ELL and struggling learners.
• Incorporate peer collaboration to encourage language development and social skills.
• Ensure materials are prepared ahead of time for smooth transitions during the game.
