Whats the big idea? Measurement is about comparison of an objects attribute to a unit. Measurements are estimates, given in units. Units are related within systems of measurement. Angle measure can be thought of as a measure of rotation. Angle ray lengths do not affect angle measure. Line plots can be used to record data and to solve problems about data. relative size liquid volume mass, length, kilometer (km), meter (m), centimeter (cm), kilogram (kg), gram (g), liter (L), milliliter (mL), inch (in), foot (ft), yard (yd), mile (mi), ounce (oz), pound (lb), cup (c), pint (pt), quart (qt), gallon (gal), hour, minute, second line plots, bar graphs, picture graphs What understandings do students need in order to think about measurement? Benchmarks Exposure to and use of measurement vocabulary Exposure to different ideas and ways of measuring Hands-on grappling MD. 1 Customary Length Conversion Table From the wiki: This is from Bill McCallum's site, Illustrative Mathematics.Students are not expected to know e.g. that there are 5280 feet in a mile. If a task is to be used as an assessment task, the conversion factors should be given to the students. However, in a teaching situation it is worth having them realize that they need that information rather than giving it to them upfront; having students identify what information they need to have to solve the problem and knowing where to go to find it allows them to engage in Standard for Mathematical Practice 5, Use appropriate tools strategically. The site is great, easy to navigate and has samples (illustrations) of questions for many of the Common Core standards k-12. Hope this is helpful. Mike This unit: STANDARDS FOR MATHEMATICAL PRACTICE 1. Make sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning. MD. 2 Charlie and 10 friends are planning for a pizza party. They purchased 3 quarts of milk. If each glass holds 8oz will everyone get at least one glass of milk? MD. 2 Possible solution: Charlie plus 10 friends = 11 total people 11 people x 8 ounces (glass of milk) = 88 total ounces 1 quart = 2 pints = 4 cups = 32 ounces Therefore 1 quart = 2 pints = 4 cups = 32 ounces 2 quarts = 4 pints = 8 cups = 64 ounces 3 quarts = 6 pints = 12 cups = 96 ounces If Charlie purchased 3 quarts (6 pints) of milk there would be enough for everyone at his party to have at least one glass of milk. If each person drank 1 glass then he would have 1- 8 oz glass or 1 cup of milk left over. MD. 2 MD. 3 Example: A rectangular garden has as an area of 80 square feet. It is 5 feet wide. How long is the garden? Example: A plan for a house includes rectangular room with an area of 60 square meters and a perimeter of 32 meters. What are the length and the width of the room? MD. 4 Example: Students measured objects in their desk to the nearest 1/2, 1/4, or 1/8 inch. They displayed their data collected on a line plot. How many object measured inch? inch? If you put all the objects together end to end what would be the total length of all the objects? MD. 5 MD. 5 a MD.6 MD. 7 Example: Joey knows that when a clocks hands are exactly on 12 and 1, the angle formed by the clocks hands measures 30. What is the measure of the angle formed when a clocks hands are exactly on the 12 and 4? Using the sextant to measure the altitude of the Sun above the horizonaltitude MD. 7 h/measurement/h/measurement/ Resource List The following list is provided as a sample of available resources and is for informational purposes only.

As part of the continuing implementation of CCGPS in the year , the current GADOE mathematics units are being augmented. We would like your assistance with this critical process. Student work samples are a vital component of the frameworks which only you can provide. If you have been using the GADOE frameworks and have student work which you would be willing to share, please send it our way. We will remove any identifiers, and include selected student work samples in the revised frameworks which are slated to be released July 1, If your student work sample is selected for inclusion we will notify you of its placement in the units via. Call for Student Work Samples Submission guidelines : Attach the work sample(s) to anin any format. Whatever works for you, works for us. Indicate the grade level, unit, and task in the body of your, and on the work sample in the upper left corner. You may cover any student/school identifiers if you wish, and we will do the same if any remain. Send thewith student work attached to the appropriate team member. To be considered for inclusion, work samples must be submitted by May 17, We look forward to seeing your students work. Call for Student Work Samples As part of the continuing implementation of CCGPS in the year , the current GADOE mathematics frameworks and units are being reviewed, revised, and augmented. We are offering an opportunity for educators to assist in this critical process. The challenge: Create a career-based mathematics task using guidelines provided to supplement and/or address gaps in the existing CCGPS frameworks units. If your task is selected for addition to a unit, you will receive a $200 honorarium per task. All work is to be original using support structures provided by the Georgia Department of Education Mathematics Team. If you are interested in participating in this challenge, please view the task creation guidelines atand get started! Task submission period begins now and closes May 1, We look forward to seeing your tasks.http://ccgps-task-submission-guidelines.wikispaces.com/ Career-Based Mathematics Task Challenge As part of the continuing implementation of CCGPS, the current CCGPS mathematics frameworks and units are being reviewed, revised, and augmented. The Georgia Department of Education is seeking qualified math educators to become part of the 2013 CCGPS Mathematics Resource Revision Team which will assist in this critical process. The scope of the CCGPS Mathematics Resource Revision Team work will include, but is not limited to: evaluating newly submitted tasks assessing the need for additional tasks assessing the order of current units and tasks editing of current units and tasks creating additional tasks to address gaps, if necessary 2013 Resource Revision Team All work will be completed collaboratively with support structures provided by the Georgia Department of Education Mathematics Team. All work is to be completed at the Georgia Department of Education, June 3rd-June 6, and June 10-13, Team members will be compensated for contracted work in the amount of $2000 and travel expenses will be reimbursed. If you are interested in becoming a part of the CCGPS Mathematics Resource Revision Team, please respond to the appropriate Georgia Department of Education contact below by March 1, In your response, please indicate grade level interest, why you would like to be part of this team, related experience, and the contact information for two references Resource Revision Team Grades K-5 Turtle Toms Mathematics Program Elementary Specialist This is it.
