Lesson 8 Slide-by-Slide Breakdown: Multiply by Applying Distributive Property with Equations LAUNCH (11:15-11:20am, 5 minutes) Slide 8: Ivan's Dog Park Problem Content: Visual of rectangular dog park: 30 m (grassy area - green) + 6 m (paved area - gray) Width: 8 m Total length: 36 m Question: "What is the total area of the dog park?" Partner Work Prompt: "Work with your partner to find the total area" "Use equations to show your thinking" Sentence frame for ELL: "8 × 36 = 8 × (__ + __...

This resource focuses on using the distributive property to solve multiplication problems. Students learn how to break apart numbers and represent multiplication problems using equations rather than visual models. Through specific examples, such as calculating the area of Ivan's Dog Park, students practice decomposing numbers (e.g., 36 as 30 + 6) and applying the distributive property by rewriting multiplication expressions (e.g., 8 × 36) in terms of sums. The resource includes guided exercises, collaborative activities like 'Turn and Talk', and key takeaway points to reinforce understanding. The aim is to develop students' ability to perform multiplication efficiently using equations, promoting a deeper understanding of the distributive property.
