spiraling
n.— «Also, instead of spending weeks on a particular math lesson, students are introduced to the concepts for a few days and revisit them later. This technique, called “spiraling,” is designed to help students build on their problem-solving skills so they can retain information over the long-term and improve test scores.» —“Everyday math puts teachers on the spot during training” by Liz Mitchell Beaufort Gazette (South Carolina) June 24, 2008.
