Algebra review, solved aloud, one textbook problem at a time.
Mrs. Oro's Study Casts talks through algebra final exam review one textbook problem at a time, naming the page and problem number before any calculation begins. Slope from two points, slope-intercept form and the Pythagorean theorem are each worked step by step, down to the sign on every subtraction.

Mrs. Oro's Study Casts turns textbook practice into something to listen to. The run of episode titles spells out the purpose: 'Algebra Final Exam Review 1', 'Algebra Final Exam Review 2', 'Algebra Final Exam Review 3'. These are review sessions, and they sound like it. Every problem comes with its page and number, such as page 313, problem 11, or page 322, problem 67. The given values are read out, and then the solving starts. Nothing gets summarised. The narrator states the formula, substitutes the numbers and does the arithmetic aloud, one operation at a time. Slope is a steady thread. It is found from two points with y2 minus y1 over x2 minus x1. It is read off an equation already written as y equals mx plus b, where the number attached to x gives it away. And it becomes the first step toward writing a full equation in slope-intercept form from a pair of points. Geometry appears as well. One excerpt works the Pythagorean theorem with legs of 6 and 8, squares of 36 and 64, a sum of 100 and a hypotenuse of 10. A second problem asks whether three given lengths could be the sides of a right triangle, which is settled by putting them into the same equation and comparing both sides. The most useful habit on display is the care taken with negative numbers. Subtraction is restated as adding the opposite, again and again. When a problem subtracts a negative 13, the narrator puts it in parentheses so that both the minus sign and the negative sign stay in view. The narration lingers on those sign changes instead of rushing past them. One episode breaks the pattern. 'Just Starting Podcast: 1' mentions Bob Sprankle's Bit by Bit reaching its 100th episode and a conference at Kean University. It then follows a speaker through an online Collaboration Center under a PBL Workshop heading, with teacher and student log-ins and projects running from kindergarten through grade 12. That speaker also says the network's largest country is Argentina, not the U.S. It is a detour away from exam review. The worked problems remain the reason to press play: exact, thorough and tied to specific pages of a textbook.
Made for: Suits a student reviewing for an algebra final who wants to hear slope, slope-intercept form and Pythagorean theorem problems solved one spoken step at a time, ideally with the matching textbook open.
What sets it apart: Instead of explaining concepts in the abstract, it ties every problem to a specific textbook page and problem number and says every arithmetic step out loud. It takes particular care with negative signs and with subtracting by adding the opposite.
