CONSTRUCTING TASK: USING A BALANCE SCALE Approximately 1 day This lesson is adapted from a Balance Scale” found at K-5_MathTeachingResources.com “Using STANDARDS FOR MATHEMATICAL CONTENT Describe measureable attributes of objects, such as length or weight. Describe several MCC.K.MD.1 measureable attributes of a single object. MCC.K.MD.2 Directly compare two objects with a measureable attribute in common, to see which object has of”/”less of” the attribute, and describe the difference. For example, directly “more compare the heights of two children and describe one child as taller/shorter. STANDARDS FOR MATHEMATICAL PRACTICE 1. Make sense of problems and persevere in solving them. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. BACKGROUND KNOWLEDGE Kindergarten students most likely will have no prior knowledge of using a balance scale. You may want to discuss with them that when something heavy is placed in our hand, our hand drops down from the weight. Then discuss that on a balance scale, the heavier an object is, the lower that side of the scale drops. Objects have multiple measureable attributes. Remind the students that it is important to identify the attribute being measured. Remember: It is important that the students clearly identify the attribute being measured. It is important that the students realize that BOTH objects must share the attribute before a comparison can be made. For more information common misconceptions, please refer to the unit overview. ESSENTIAL QUESTIONS Does how I measure matter? How can I compare two objects by their size? What attributes of an object can be measured? How can I organize my information?
