Longview ISD 4th Grade Math Unit 12 4 th Grade TEKS with Specificities UNIT 12 Relating Measurement and Geometry 4.11 Measurement. The student 4.11C use concrete models of standard applies measurement concepts. cubic units to measure volume The student is expected to Include: Investigations estimate and measure to solve  Concrete models should include cubes and  ”Seeing Solids and Silhouettes” problems involving length blocks Investigation 2 Sessions 3 and 4 (including perimeter) and area.  “Silhouettes of Cube Buildings” The student uses measurement 4.11D estimate volume in cubic units Investigation 4 “The Cube Toy Project” tools to measure capacity/volume Include: and weight/mass. The student is  Estimate before actually finding the volume expected to: through exploration  Use linking cubes, foam cubes, wooden 4.11A estimate and use measurement cubes etc. Enrichment Centers (i.e., AIMS) tools to determine length (including perimeter), area, 4.11E explain the difference between capacity and weight/mass using weight and mass NOTES standard units, SI (metric) and Include: customary. Weight Include:  Weight is the gravitational pull on an object  Measurement should be hands-on  Customary units of measurement are used application such as ounces, pounds, and tons  Include and make the connections  Scales are used in measuring weight between the representations: concrete, Mass pictorial, abstract,  Mass is the amount of matter something  Metric units of measurement contains  Customary units of measurement  Metric units of measurement are used such  Area and perimeter as grams and kilograms  Arrays with tiles  A balance is used in measuring  Linear lines for dimensions Length 4.12 Measurement. The student  Inches, feet, yards applies measurement concepts. The student measures time and  Centimeter, meter, kilometer temperature (in degrees Capacity Fahrenheit and Celsius). The  Cups, pints, quarts, gallons student is expected to:  Milliliters, liters Mass/weight 4.12A use a thermometer to measure  Ounces, pounds (weight - use scales) temperature and changes in  Grams, kilograms (mass - use balance) temperature  Students measure/hands-on with 4.11B perform simple conversions thermometers between different units of length, Vocabulary: between different units of capacity,  increase, decrease, drop, rise and between different units of weight within the customary 4.12B use tools, such as a clock with measurement system; gears or a stopwatch, to solve Include: problems involving elapsed time  Estimate first Include:  Measurement should be hands-on  Students solve problems using clocks with application; provide students common gears, etc. items for developing concepts  Include both analog and digital clocks  Customary (inch, foot, yard, mile)  Elapsed time -- "How long was the party?  Capacity - amount object holds; weight - Our party started at 2:00 and was over at gravitational pull on an object 4:30. The amount of elapsed time is 2  Use conversion of customary hours and 30 minutes. measurements (e.g. 6 inches and 1/2 foot)  Range of time -- students will be asked to in problem solving choose the clock that is in between 2:00  1 foot = 1/3 yard and 2:30 (between a range of time.)  1 inch = 1/12 foot  May use "T" charts to record  1 quart = ¼ gallon  1 pint = ½ quart 1 cup = ½ pint  1 ounce = 1/8 cup  1 ounce = 1/16 pound  3 ft = 1 yard  4 qts = 1 gallon
