A middle school math teacher wants students to learn how to calculate the area of a​ triangle, which involves multiplying the​ triangle's base​ (i. e., bottom​ side) by its height​ (measured by a line going perpendicular from the base to the opposite​ angle) and then dividing by 2. The formula A​ = ½ ​(b×h​) is the mathematical equivalent. What strategies might the teacher use to help students understand and remember this​ procedure?
