Students demonstrate understanding of plane and solid geometric objects. They use this knowledge to show relationships and solve problems. 3.5 know the definitions of right angle, acute angle and obtuse angle. Students organize, represent and interpret numerical and categorical data, and clearly communicate their findings. Students make predictions for simple probability situations.
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.
