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. 2.1 use estimation to verify the reasonableness of calculated results 2.2 apply strategies and results from simpler problems to more complex problems 2.3 use a variety of methods such as words, numbers, symbols, charts, graphs, tables, diagrams and models to explain mathematical reasoning 2.4 express the solution clearly and logically using appropriate mathematical notation and terms and clear language, and support solutions with evidence, in both verbal and symbolic work 2.5 indicate the relative advantages of exact and approximate solutions to problems and give answers to a specified degree of accuracy 2.6 make precise calculations and check the validity of the results from the context of the problem 3. Students move beyond a particular problem by generalizing to other situations.
