3. Time to Sprint! Multiply Decimals

4. Multiplying Fractions Use Interwrite Tools

5. Application Problem Mrs. Golden wants to cover her 6.5 foot by 4 foot bulletin board with silver paper that comes in 1-foot squares. How many squares does Mrs. Golden need to cover her bulletin board? Will there be any fractional pieces of silver paper left over? Explain why or why not. Draw a sketch to show your thinking. Let’s draw out what this problem is saying!

6. Application Problem ~ ANSWER! Mrs. Golden wants to cover her 6.5 foot by 4 foot bulletin board with silver paper that comes in 1-foot squares. How many squares does Mrs. Golden need to cover her bulletin board? Will there be any fractional pieces of silver paper left over? Explain why or why not. Draw a sketch to show your thinking.

7. Teacher notes The following will need to be created ahead of time: * Copies of Rectangles A to E for student groups Students will need: * Problem Set * Patty paper units for tiling * Mystery rectangles A - E Concept Development

8. Breaking News! The Eureka Laboratory has one again lost 4 rectangles. (We really need to get those locks fixed! ) 5 th grade, we once again need your help to determine those areas and make everything right again! Ms. Patty Paper will be back to help you with the discovery! Good luck! Area = length x width

9. Rectangle A  Place as many tiles on Rectangle A as possible. * Place a whole patty paper there and just shade ¼

10. Rectangle A  Area = 4 ½ x 2 ½ = _______ Draw here!

11. Ok detectives, you are prepared for the rest of the mission! Work with your group to find the length, width, and area of Rectangles B, C, and D using Ms. Patty paper to help you!  Record your findings on your Problem Set.  Answer the last two questions (#5 & 6) in the time remaining.  You may record your tiling without drawing each tile if you wish!

12. 5th Grade Module 5- Lesson 11 K. Clauson Take 2 minutes to check your answers with your partner. Let’s share any insights you had while solving these problems. Compare the rectangles we tiled today to the rectangles we tiled yesterday? What do you notice? How did that change the way we had to tile? Which rectangles were the easiest to tile? Which was the hardest? Why? How could our work in Lessons 10 and 11 relate to a real world experience?
