Math
In fourth grade math, students will investigate the base-ten number system by reading, writing, representing, comparing and rounding whole numbers and decimals; demonstrate fluency in computations with whole numbers using 1 and 2 digit numbers; develop strategies for performing computations mentally; and generate equivalent forms of fractions and decimals to estimate, add, and subtract decimals and fractions with like denominators. Students will count money and make change; examine prime and composite numbers; make simple measurement conversions of units; solve multi-step problems; and develop strategies to find perimeter, area, and volume. In geometry, students will investigate, classify, and model plane figures and solids. They will plot locations in the first quadrant of a coordinate system and make transformations of slides, flips, and turns; use words, tables, and graphs to analyze patterns and relationships to make predictions and solve problems; represent unknowns as variables in equations and inequalities and relate how change in one variable affects the value of a related variable. Students will gather and organize data in tables, charts, and graphs and make predictions based on interpretations and appropriate display of data; use mode, median, and range to describe the characteristics of data; conduct simple probability experiments and make predictions of possible outcomes ordering events as impossible, unlikely, equal, likely, and certain-to-happen; and make lists to display all possible combinations of different sets of items.
