Grade Four
The fourth-grade standards place emphasis on multiplication and division with whole numbers and solving problems involving addition and subtraction of fractions and decimals. Students will continue to learn and use the basic multiplication facts as they become proficient in multiplying larger numbers. Students also will refine their estimation skills for computations and measurements and investigate relationships between and among simple two-dimensional (plane)figures and three-dimensional (solid) figures. Students will identify and draw representations of points, lines, line segments, and rays. Students will graph points in the first quadrant in the coordinateplane and extend and duplicate patterns. Concrete materials and two-dimensionalrepresentations will be used to solve problems involving perimeter, patterns, probability, andequivalence of fractions and decimals. Students will recognize a geometric transformation, such as reflection (flip), translation (slide), and rotation (turn).
While learning mathematics, students will be actively engaged, using concrete materials and appropriate technologies such as calculators and computers. However, facility in the use of technology shall not be regarded as a substitute for a student’s understanding of quantitative concepts and relationships or for proficiency in basic computations.
Mathematics has its own language, and the acquisition of specialized vocabulary and language patterns is crucial to a student’s understanding and appreciation of the subject. Students should be encouraged to use correctly the concepts, skills, symbols, and vocabulary identified in the following set of standards.
Problem solving has been integrated throughout the six content strands. The development of problem-solving skills should be a major goal of the mathematics program at every grade level. Instruction in the process of problem solving will need to be integrated early and continuously into each student’s mathematics education. Students must be helped to develop a wide range of skills and strategies for solving a variety of problem types.
