1. Welcome to the Make Math Meaningful Audio-Web Conference Feb. 25, 2004 Sheryl Beglinger Comprehensive Center Region VI smbeglinger@wisc.edu

2. Measurement

3. Emphasis of these Content Standards by Grade Levels (Principles and Standards for School Mathematics, National Council of Teachers of Mathematics, pg. 30)

4. Instructional programs for prek through grade 12 should enable all students to: Understand measurable attributes of objects and the units, systems, and processes of measurement Apply appropriate techniques, tools, and formulas to determine measurements

5. Understand measurable attributes of objects and the units, systems, and processes of measurement –Need to be able to select units appropriate to the attribute being measured feet, ounces, square yards, etc. –Know the common units of the English and metric systems Have mental images of benchmarks for judging and comparing size –paper clips weighs about a gram, width of their forefinger is about a centimeter

6. Understand measurable attributes of objects and the units, systems, and processes of measurement –Express measurements in equivalent forms 150 centimeters = 1.5 meters or 3 feet = 1 yard Cadbury Maths Animal Weigh In –Understand, select, and use units of approximate size and type to measure angles, perimeter, area, surface area, and volume Shape Explorer Geoboards in the Classroom Don’t Fence Me In Mini-metric Olympics Home Improvement WebQuest

7. Understand measurable attributes of objects and the units, systems, and processes of measurement –Realize that measurements in the real world are approximate Footprints: Take a Step into Estimation –Explore how measurements are affected when one attribute to be measured is held constant and the other is changed Spaceship Builder Perimeter Explorer

8. apply appropriate techniques, tools, and formulas to determine measurements –Develop strategies for estimating the perimeters, areas, and volume of irregular shapes

9. apply appropriate techniques, tools, and formulas to determine measurements –Develop strategies for estimating the perimeters, areas, and volume of irregular shapes

10. apply appropriate techniques, tools, and formulas to determine measurements –Select and apply appropriate standard units and tools to measure length, area, volume, weight, time, temperature, and the size of an angle Measure It! Shape, Space, and Measure: Measures Clock Wise Elapsed Time Triangle Explorer

11. apply appropriate techniques, tools, and formulas to determine measurements –Develop, understand, and use formulas to find the area of triangles, parallelograms, trapezoids, and circles and develop strategies to find the area of more complex shapes. Area Formula Lab Module Math –Solve problems involving scale factors, using ratio and proportion California Here We Come!

12. apply appropriate techniques, tools, and formulas to determine measurements –Develop strategies to determine the surface areas and volume of prisms, pyramids, and cylinders
