Problem Attic is a free service that allows you to quickly create practice tests and flashcards for social studies, language arts, mathematics, and science. I've featured it a couple of times since its launch last year. Problem Attic recently expanded again to include 4600 more practice questions from tests in Hawaii, Kentucky, Minnesota, Ohio, and New Jersey. Problem Attic also has a new set of 1700 math challenges from UNC Charlotte.
If you have been creating problem flashcards in Problem Attic you'll be happy to know that the interface has been tweaked to ensure that problem cards will always fit on the size screen that you're using.
In the next few weeks Problem Attic will add more services including support for free-response math questions aligned to Common Core standards.
Applications for Education
Years ago one of my colleagues used old exam questions as review activities with his students. Problem Attic takes that concept and makes it easy for any teacher to build review activities based on problems from actual tests that students have taken. Students can also use Problem Attic to find a big collection of questions that they can use to help them prepare for tests in mathematics, social studies, language arts, and science.
