How are calculators usedeffectively in the classroom?

Have students decide onreasonableness of calculator answersbefore they do the calculation

Use questions & discussion to help Use questions & discussion to helpstudents think actively about theprocesses used to arrive at answers

Mix in problems that are easier to solveby hand or that become complicated onthe calculator so that students will usethe calculator discriminately

Common Messages… Appropriate use of calculators/technology is

encouraged. The existence of calculators/technology does not

diminish the need for computational fluency. Calculators/technology can support increased

understanding of mathematics. Calculators/technology can support increased

understanding of mathematics. Calculators/technology can support effective

teaching. Calculators/technology are commonly used in the

workplace, therefore students should learn to usethese tools to solve problems.

Teachers are responsible for appropriate andeffective use of calculators/technology.

Questions to think about What are the pros and cons of allowing students to use

calculators only after they have proven their ability to computewith pencil and paper?

How can calculators be used to help students develop a broaderview of mathematics problem solving?Can students be taught estimation techniques that will help Can students be taught estimation techniques that will helpthem recognize whether computer or calculator results arereasonable? If so, how?

How can computers be used to help students develop themathematical reasoning and problem-solving concepts requiredin the real world?

How can computers be used in mathematics programs tosimulate problem-solving situations and applications?
