Arkansas: EF Math Standards

EF.2

• EF.2.MAA.1 Represent constraints by equations or inequalities and by systems of equations and/or inequalities (two and three variable systems); interpret solutions as viable or nonviable options in a modeling context (e.g., represent inequalities describing nutritional and cost constraints on combinations of different foods)
• EF.2.MAA.2 Rearrange formulas to highlight a quantity of interest using the same reasoning as in solving equations (e.g., rearrange Ohm’s law V = IR to highlight resistance R)
• EF.2.MAA.3 Give an informal argument for the formulas for the circumference of a circle, area of a circle, and volume of a cylinder, pyramid, and cone; use dissection arguments, Cavalieri’s principle, and informal limit arguments
• EF.2.MAA.4 Give an informal argument using Cavalieri’s principle for the formulas for the volume of a sphere and other solid figures
• EF.2.MAA.5 Use volume formulas for cylinders, pyramids, cones, and spheres to solve problems
