be successful problem solvers and use mathematics efficiently and
effectively in daily life. The process standards are integrated at
every grade level and course. When possible, students will apply mathematics
to problems arising in everyday life, society, and the workplace.
Students will use a problemsolving model that incorporates analyzing
given information, formulating a plan or strategy, determining a solution,
justifying the solution, and evaluating the problemsolving process
and the reasonableness of the solution. Students will select appropriate
tools such as real objects, manipulatives, paper and pencil, and technology
and techniques such as mental math, estimation, and number sense to
solve problems. Students will effectively communicate mathematical
ideas, reasoning, and their implications using multiple representations
such as symbols, diagrams, graphs, and language. Students will use
mathematical relationships to generate solutions and make connections
and predictions. Students will analyze mathematical relationships
to connect and communicate mathematical ideas. Students will display,
explain, or justify mathematical ideas and arguments using precise
mathematical language in written or oral communication.
(5) Students are encouraged to participate in extended
learning experiences such as career and technical student organizations
