  • 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.
• MA 3.1.2 Students will demonstrate the meaning of multiplication and division with whole numbers and compute accurately.
  • MA 3.1.2.a Add and subtract within 1,000 with or without regrouping.
  • MA 3.1.2.b Select and apply the appropriate methods of computation when solving one- and two- step addition and subtraction problems with four-digit whole numbers through the thousands (e.g., visual representations, mental computation, paper-pencil).
  • MA 3.1.2.c Use drawings, words, arrays, symbols, repeated addition, equal groups, and number lines to explain the meaning of multiplication.
