Reminder: Check the Lower School lost and found before the Thanksgiving holiday. To help you remember, all the problems this week relate to lost things that were later found.
Level 1: Lost Lego: If one of your Lego bricks gets vacuumed up in June, and then pops out of the vacuum 3 months later, what month did it reappear?
Level 2: Long Lost Watch: A man named Ed lost his wristwatch 53 years ago when he was in the Navy. Someone returned it to him in 2012. What year did he lose it?
Level 3: A Long Way Down: Students at Stanford University sent up a weather balloon with a GoPro camera attached so they could take pictures of the Grand Canyon from miles above the ground. When the camera fell back to Earth, the students couldn’t find it. Two years later, some hikers in the Grand Canyon found it! If the camera went 5 miles up, and then came 5 miles down, how many feet did the camera travel? (Hint: One mile = 5,280 feet)
SUPER BONUS: If you lost your sneakers 10 months ago and found them 4 months later, and you lost your favorite shirt 2 years ago and found it halfway between losing and finding your sneakers, how long were you missing the shirt? A drawing or bar model might be helpful.
Thank you to Bedtime Math for the problem idea.
