You are on a gameshow and the host shows you three doors. Behind one door is a suitcase with $1 million in it, and behind the other two doors are sacks of coal. The host tells you to choose a door, and that the prize behind that door will be yours to keep.
You point to one of the three doors. The host says, “Before we open the door you pointed to, I am going to open one of the other doors.” He points to one of the other doors, and it swings open, revealing a sack of coal behind it.
“Now I will give you a choice,” the host tells you. “You can either stick with the door you originally chose, or you can choose to switch to the other unopened door.”
Should you switch doors, stick with your original choice, or does it matter?

Clayton students volunteered to help renovate the playground for the Kindergartners at Towles Elementary school. City regulations require the sand underneath the swings be at least 15 inches deep. The sand under both swing sets was only 12 inches deep when the renovation started.
The rectangular area under the small swing set measures 9 feet by 12 feet and required 40 bags of sand to increase the depth by 3 inches. How many bags of sand will the students need to cover the rectangular area under the large swing set if it is 1.5 times as long and 1.5 times as wide as the area under the small swing set?

The students in Madddie’s class built some solar-powered robots which they raced in the cafeteria of the school.

∙ Robot B traveled 5 meters in 7.5 seconds
∙ Robot B traveled 7.5 meters in 5 seconds
∙ Robot B traveled 2/5 meters per second
∙ Robot B traveled 3/2 meters per second
∙ None of these are true
B) How do the speeds of the robots compare? (Choose one)
∙ The Robots all traveled at the same speed, they just left at different times
∙ Robot (A/B/C) is the fastest and Robot (A/B/C) was the slowest
∙ There is not enough information given to compare how fast the robots traveled
