Standard: Use Math to Solve Problems and Communicate

Component of Performance How activity addresses component Understand, interpret, and work with pictures, numbers, and symbolic information. Students will understand three types of estimation strategies: front end, estimation with rounding and estimation with grouping. Apply knowledge of mathematical concepts and procedures to figure out how to answer a question, solve a problem, make a prediction, or carry out a task that has a mathematical dimension Students learn to solve problems using estimation. Students practice calculator skills when learning about estimation Define and select data to be used in solving the problem Students identify the prices of items on a receipt when finding the sum using estimation Determine the degree of precision required by the situation Students determine what type of estimation is appropriate for estimating the sum of a variety of items. Solve problem using appropriate quantitative procedures and verify the results are reasonable Students determine what type of estimation is appropriate for estimating and verify the results with a calculator. Communicate results using a variety of mathematical representations, including graphs, charts, tables, and algebraic models Students will record their estimates as presented with prices for items while shopping and write a short essay explaining their observations.

Purposeful, Transparent, Building Expertise

Purposeful and Transparent Student will practice rounding prices so they can better manage their money while shopping. Contextual Students will use these estimation skills when they shop. The students also have discussed situations in their lives where estimating a sum could be used. Building Expertise The plan uses the knowledge the students have about money and shopping and encourages them to use math to improve their shopping experience.
