Nebraska Core Academic Content Standards
NE.MA.3.1. NUMBER: Students will communicate number sense concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.
MA.3.1.1. Numeric Relationships: Students will demonstrate, represent, and show relationships among whole numbers and simple fractions within the base-ten number system.
MA.3.1.1.f. Show and identify equivalent fractions using visual representations including pictures, manipulatives, and number lines.
MA.3.1.1.g. Find parts of a whole and parts of a set using visual representations.
MA.3.1.1.h. Explain and demonstrate how fractions ¼, ½, ¾ and a whole relate to time, measurement, and money, and demonstrate using visual representation.
MA.3.1.1.i. Compare and order fractions having the same numerators or denominators using visual representations, comparison symbols, and verbal reasoning.
NE.MA.3.3. GEOMETRY: Students will communicate geometric concepts and measurement concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.
MA.3.3.1. Characteristics: Students will identify and describe geometric characteristics and create two- and three-dimensional shapes.
MA.3.3.1.c. Draw lines to separate two-dimensional figures into equal areas, and express the area of each part as a unit fraction of the whole.
