Students describe and compare the attributes of plane and solid geometric figures and use their understanding to show relationships and solve problems. Students conduct simple probability experiments by determining the number of possible outcomes, and make simple predictions. Students make decisions about how to approach problems. 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 Coaster Connections 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.
