Math Marvels build on their work with fractions and learn to compute unit rates with fractions in the numerator or the denominator. They determine whether two quantities are in a proportional relationship by looking at values in a table, a graph on a coordinate plane, and an equation. They identify the constant of proportionality from a table or an equation. They also learn to represent proportional relationships with equations and graphs and to explain what any point (x, y) in the graph means. Math Marvels extend their knowledge of rates, unit rates, proportions, and percent as they learn to solve problems about interest, taxes, mark-ups and mark-downs, and gratuities and fees. They solve multi-step ratio and percent problems in real-world contexts.
