CCSS Convert unit among different-sized measurement units within AF 1.4G5.MD.1 Express simple conversions in standard symbolic form a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions (e.g., ___ inches = ___ feet x 12). in solving multi-step, real world problems. MG 1.1 UNDERLYING SKILLS AND CONCEPTS: estimate/measure weight (metric units) Choose the appropriate tools and units (metric and U.S.) and estimate and measure the length, liquid volume, and weight/mass of given objects. Estimate Weight in Grams and Kilograms a K ey Ide The metric system uses grams (g) and kilograms (kg) to measure the heaviness of objects. Benchmarks for You 1 kilogram is about 2 pounds. 1 kilogram is the same as 1,000 grams. 1 kg 1,000 g E x am p l E 1 gram is about the weight of a large paper clip. There are 28 grams in 1 ounce. 1 How heavy am I? Mr. Dunn bought 2 kilograms of chocolate. How many grams of chocolate did he buy? Find 2 1,000. 2 1,000 2,000 2 kg 2,000 g 0 3 So, Mr. Dunn bought 2,000 grams of chocolate. E x am p l E 1 2 Kilograms 2 Choose the best unit to measure the weight of a bag of apples. A. gram B. millimeter C. meter D. kilogram To decide, look at the answer choices. Choices B and C measure length, not weight. Choice A is a unit for measuring very light objects. So Choice D, kilogram, is the best unit of measure. page 308 Chapter 26 – Lesson 4 C – © CSL Associates, Inc. All rights reserved.
