Lesson Plan : Metric System Conversions

Teacher Name:
 Cindy Riggs
Grade:
 Grade 9-10
Subject:
 Science

Topic:
 Metric System Conversions
Content:
 Learning how to convert metric measurements within the Metric System Vocabulary: conversion, units, meter, gram, liter, metric system of measurement, standards, deci, deca, milli, hecto, kilo, centi
Goals:
 For students to be able to convert metric measurements within the Metric System
Objectives:
 Students will be able to convert metric measurements within the Metric System. Students will be able to use the "stairstep" and convert metric units by using the metric prefixes correctly. Students will be able to move the decimal to its correct position in coverting metric measurements.
Materials:
 Chalkboard, textbook, class notes, calculator, help sheets, pencil, and paper
Introduction:
 Students will be reminded of the purpose of a universal measuring system. Teacher will also review material previously taught as part of this unit of study: importance of standards in measurement and the numerical values of prefixes used within the metric system
Development:
 Teacher will lecture as well as demonstrate on the board the mathematical significance of decimals holding place value. The teacher will demonstrate the proper use of the "stairsteps" in determining conversion values.
Practice:
 Students will be given two days of actual guided practice. Those days will consist of a practical application lab where they are measuring objects, determining English equivalents of meter, centimeter, gram, etc., and this day of solving problems with teacher/peer assistance.
Accommodations:
 Students with IEPs will be allowed to use the "stairstep" sheet during all problem-solving, i.e. guided practice, homework, quiz, and test. General education students will be expected to learn "stairstep" and be able to apply its use on all individual work. Visually impaired students will have preferential seating during lecture. Exceptionally proficient students will research extreme values of metric measurements such as a nanoliter.
Checking For Understanding:
 At the end of this unit, grades will be recorded for notes in notebook, application lab, homework, guided practice, quiz, and test.
Closure:
 Since students must learn this process for future science classes such as chemistry and physics, this concept will be reviewed many times throughout the year.
Evaluation:
 All students will be given the same test since all students will be expected to be proficient on the state-mandated tests. However, the IEP students will be allowed to use the "stairstep" and class notes, if needed. All students will be allowed to use a calculator.
Teacher Reflections:
 There are many mathematical concepts for some of the IEP students to grasp. They must always be able to use their "stairstep" help sheet when doing metric conversion. I will also research a metric conversion "calculator" for some of my students.
