Here's your lesson plan: Area & Perimeter Lesson Plan Overview Objective: Students will calculate area and perimeter of rectangles using multiplication and addition, and explain the difference between area (space inside) and perimeter (distance around), shown by correctly solving 3 problems and explaining the difference in their own words. Grade: 4th Grade Math Duration: 60 minutes Format: Traditional (Hook → Teach → Guided Practice → Independent Practice → Close) Prior Knowledge: Students can multiply and measure with a ruler Standards: CCSS.MATH.CONTENT.4.MD.A.3 (Apply area and perimeter formulas for rectangles) Materials & Resources Required: Grid paper (1 sheet per student) Rulers (1 per student) Projector/document camera Chart paper or whiteboard Optional: Color tiles or square manipulatives (for struggling students) Index cards for exit ticket Prep: None (materials ready to go) Lesson Timeline 1. Hook / Engage (8 minutes) Activity: Show two rectangles on the projector: one that's 10×2 and one that's 6×4. Ask: "Which shape uses more fencing to go around? Which shape has more space inside?" Teacher moves: Display rectangles side by side Ask: "Talk to your partner: What do you notice? Which needs more fencing?" Call on 2-3 students to share predictions Say: "Today we'll learn the math behind these questions, area and perimeter." Students do: Look at shapes Turn-and-talk with partner (1 minute) Share predictions Transition: "Let's start with perimeter, the distance around a shape." Check: Are students making predictions? Do they understand "around" vs. "inside"? 2. Direct Teach: Perimeter (12 minutes) Activity: Model calculating perimeter step-by-step using a rectangle on grid paper. Teacher moves: Draw a 5×3 rectangle on document camera Say: "Perimeter is the distance around. Let's walk around this rectangle." Point to each side: "Top is 5, right side is 3, bottom is 5, left side is 3." Write: 5 + 3 + 5 + 3 = 16 Say: "The perimeter is 16 units. It's like putting a fence around a yard—you need to know all four sides." Model one more: 4×6 rectangle (perimeter = 20) Students do: Watch and follow along Answer when called: "What's the length of this side?" Copy examples into notes Transition: "Now you try one with me." Check: Ask: "If I have a rectangle that's 7 units by 2 units, what's the perimeter?" (Cold call 2 students) 3. Guided Practice: Perimeter (8 minutes) Activity: Students calculate perimeter of 3 rectangles with teacher support. Teacher moves: Display 3 rectangles with dimensions: 8×3, 6×5, 10×4 Say: "On your grid paper, calculate the perimeter of each. Show your work: add all four sides." Circulate, check work, ask: "How did you get that number?" After 5 minutes, review answers as a class Students do: Work independently on grid paper Calculate: 8+3+8+3=22, 6+5+6+5=22, 10+4+10+4=28 Share answers when called Transition: "Great! Now let's talk about area, the space inside." Check: Scan work while circulating. Are students adding all 4 sides? Common mistake: only adding 2 sides. 4. Direct Teach: Area (10 minutes) Activity: Model calculating area using grid paper and introduce length × width formula. Teacher moves: Draw a 5×3 rectangle on grid paper Say: "Area is the space inside. Let's count the squares." Count: "Row 1 has 5 squares, row 2 has 5, row 3 has 5. That's 5+5+5=15 squares." Say: "There's a faster way: 5 rows × 3 squares each = 15. Area = length × width." Model one more: 4×6 rectangle (area = 24 square units) Say: "Notice: We say 'square units' for area because we're counting squares." Students do: Count squares with you Practice formula: "6 × 4 = ?" Write formula in notes Transition: "Let's try area together." Check: Ask: "What's the area of a 7×2 rectangle?" (Answer: 14 square units) 5. Guided Practice: Area vs. Perimeter (10 minutes) Activity: Students calculate BOTH area and perimeter for the same rectangles. Teacher moves: Display 3 new rectangles: 9×2, 5×5, 8×6 Say: "Find BOTH area AND perimeter for each. Label them clearly." Circulate, ask: "Which is which? How do you remember?" After 6 minutes, review answers together Emphasize: "Perimeter = add sides (distance around). Area = multiply (space inside)." Students do: Calculate both measurements for each rectangle Label: "A = __" and "P = __" Explain difference when asked Transition: "Time to practice on your own!" Check: Listen for: Can students explain the difference? Are they mixing up the formulas? 6. Independent Practice (8 minutes) Activity: Students create their own rectangle, calculate area and perimeter, and explain the difference. Teacher moves: Say: "Draw a rectangle on your grid paper. Any size between 3-10 units." Instructions on board: "1) Draw your rectangle. 2) Calculate area. 3) Calculate perimeter. 4) Write one sentence: How are area and perimeter different?" Circulate, support struggling students Students do: Draw rectangle Calculate both measurements Write explanation Transition: "Let's wrap up with an exit ticket." Check: Look for: Correct calculations? Clear explanation of difference? 7. Close / Exit Ticket (4 minutes) Activity: Quick assessment to check understanding. Teacher moves: Display rectangle: 12×3 Say: "On a blank piece of paper, answer: 1) What's the area? 2) What's the perimeter? 3) In your own words, what's the difference?" Collect as students finish Say: "Tomorrow we'll use this to find area and perimeter of real classroom objects!" Students do: Answer 3 questions Turn in exit ticket Check: Review exit tickets to identify who needs reteaching tomorrow. Differentiation Struggling Students: Provide color tiles or square manipulatives to physically build rectangles Start with smaller numbers (3×2, 4×3) Use sentence frames: "Perimeter = __ + __ + __ + __. Area = __ × __." Advanced Students: Challenge: "Can two different rectangles have the same perimeter but different areas?" (Yes: 6×3 and 5×4 both have P=18 but different areas) Extension: Find area and perimeter of L-shaped figures ELLs (Spanish Speakers): Pre-teach vocabulary with visuals: "Perimeter = perímetro (around), Area = área (inside)" Sentence frames: "The perimeter is __ because __." "The area is __ square units." Pair with English-proficient buddy for turn-and-talk Assessment During Lesson (Formative): Cold calling during direct teach (check understanding) Scanning work during guided practice (identify errors early) Exit ticket (3 questions to assess mastery) Mastery Looks Like: Student correctly calculates area using length × width Student correctly calculates perimeter by adding all 4 sides Student can explain: "Area is space inside, perimeter is distance around" Exit Ticket Criteria: Area of 12×3 = 36 square units ✓ Perimeter of 12×3 = 30 units ✓ Explanation shows understanding of difference ✓ Homework (10 minutes) Purpose: Practice calculating area and perimeter Task: Find 3 rectangular objects at home (book, table, door). Measure the length and width (in inches). Calculate area and perimeter for each. Bring your work to class tomorrow. Time Estimate: 10 minutes Support: If stuck, students can email you or check the example we did in class. Teacher Prep Key Emphasis: Perimeter = add (distance around). Area = multiply (space inside). Use real-world language: "fencing" for perimeter, "carpet" for area Common Misconceptions: Students confuse which formula to use Students forget to add ALL four sides for perimeter Students forget to say "square units" for area Questions to Prep: "What's the difference between area and perimeter?" "Why do we multiply for area?" "Can you show me which is which on this rectangle?" If Running Long: Skip the "create your own rectangle" activity, just do exit ticket If Extra Time: Let advanced students explore: Can rectangles with same perimeter have different areas? Management Note: During independent work, circulate to ELL students first to check understanding What would you like? - Adjust timing/activities - Expand differentiation/assessment - Add materials/handouts, reformat - Align to standards more specifically, - try an alternative approach - something else?"
