This is a straightforward question. I'd like to make all of you students into teachers for a minute ... Let's create a test question!


  • Do we have to specify angle AOB?

  • Is there a better way to say something without actually saying it?

  • What other instructions and given information could we provide that would lead to the same answer?

  • What is the best question here?

How much of the description is necessary in order to find the solution?

"If an equilateral triangle and three isosceles triangles together make a rhombus, what must the angles in the rhombus be?"

Do we really need to know that it's a rhombus?

Could we just be told it's a parallelogram?

How common are self-scanning scams? If anonymous online questionnaires are any indication, very common. When Voucher Codes Pro, a company that offers coupons to internet shoppers, surveyed 2,634 people, nearly 20 percent admitted to having stolen at the self-checkout in the past. More than half of those people said they gamed the system because detection by store security was unlikely. A 2015 study of self-checkouts with handheld scanners, conducted by criminologists at the University of Leicester, also found evidence of widespread theft. After auditing 1 million self-checkout transactions over the course of a year, totaling $21 million in sales, they found that nearly $850,000 worth of goods left the store without being scanned and paid for.
