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 learn the meaning of the various lines on a ruler. 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 will use basic knowledge of fractional parts to help understand what the lines on a ruler mean. Define and select data to be used in solving the problem Students will determine which measurement tool should be used to measure an object and what lines are needed to determine the length of an object. Determine the degree of precision required by the situation Students will decide how accurate their measurement needs to be. Solve problem using appropriate quantitative procedures and verify the results are reasonable Students will be able to accurately measure an object and decide of the measurements are reasonable. Communicate results using a variety of mathematical representations, including graphs, charts, tables, and algebraic models Students will answer questions requiring measurements and communicate their results verbally and with illustrations.

Purposeful, Transparent, Building Expertise

Purposeful and Transparent The activities all relate to the student goal of learning to measure accurately with a ruler. There is lots of practice so students can assess their learning as they go along. Contextual Since the students came up with real life uses for measurement the lesson is clearly related to their goals. The students are actively involved as each student constructs his or her own "inch" to measure with. Students then transfer this skill to rulers and other measuring devices. Building Expertise The lesson builds on the students' prior knowledge of fractions (starting with halves) to increase their knowledge of the divisions in the "inch."
