This lesson covers a review of elementary algebra, specifically writing word problems as algebraic expressions, drawing pictures from descriptions, and problem-solving to solve the problem. The examples given include finding the length of a board that is cut into two pieces, finding the measure of an angle's complement, and finding the measure of the third angle in a triangle given the measures of the other two angles. The lesson emphasizes the importance of understanding the problem and using techniques such as drawing a picture or working with concrete examples to arrive at solutions.
