Order of Operations and Properties

Mrs. Taylor's math class covers various topics including the slope-intercept form, order of operations, equivalent fractions, and mental math strategies. The class begins with an introduction to the day's topic, followed by detailed explanations and problem-solving exercises. Students learn to apply the slope-intercept form, use PEMDAS for order of operations, identify equivalent fractions, and employ mental math strategies like making 10.
