They use grids, tables, graphs, and charts to record and analyze data. Students compute with very large and very small numbers, positive and negative numbers, decimals and fractions and understand the relationship between decimals, fractions and percents. They understand the relative magnitudes of numbers. Students perform calculations and solve problems involving addition, subtraction and simple multiplication and division of fractions and decimals. Students use variables in simple expressions, compute the value of the expression for specific values of the variable, and plot and interpret the results.
Students understand and compute volumes and areas of simple objects.
Students identify, describe, draw and classify properties of, and relationships between, plane and solid geometric figures. Students display, analyze, compare and interpret different data sets, including data sets that are not the same size. Students make decisions about how to approach problems. 1.1 analyze problems by identifying relationships, discriminating relevant from irrelevant information, sequencing and prioritizing information, and observing patterns 1.2 determine when and how to break a problem into simpler parts 2. Students use strategies, skills and concepts in finding solutions.
