 Mrs. Walls' Math Blog (Week of 4.15.19)We will finish Chapter 9: Length in Metric Units.  In this chapter, students will learn how to measure using centimeters and meters and also solve problems about adding and subtracting lengths.  Lessons this week include measuring the lengths of objects in both centimeters and meters to explore the inverse relationship between size and number of units, estimating the lengths of objects in meters, and measuring and then finding the difference in the lengths of two objects.Students will be taking their Chapter 9 Test on Thursday, April 18.Why teach this?To increase children's understanding of the measurement units centimeter and meter, give them opportunities to choose the most appropriate unit to use in various situations.  When choosing, children should consider the length to be measured and the level of precision needed.  When asking children to choose the best unit to use, you can connect this to the understanding of the inverse relationship between the size of a unit and the number of units used to measure a length.  For example, when measuring the length of a park or playground, the number of meters would be much less than the number of centimeters.  Although both units could be used to describe the length, it is more practical in this example to measure the length in meters.Because the United States continues to use the customary system of measures, children may be more familiar with measuring and estimating lengths in inches and feet than in centimeters and meters.  The best way to help children become accustomed to measuring and estimating with units in the metric system is to provide many measuring experiences.In second grade, children are beginning to relate units they may have heard about to actual distances.  They begin to use units units and iterations of units as benchmarks when estimating and for checking that an answer to a problem expressed in those units is reasonable.Chapter 9 Vocabulary-For each chapter, I will be providing a list of important vocabulary words related to our in class learning.  Developing student's math language is a great way to improve their problem solving skills (think of complex word problems!).centimeter- a unit of length in the metric system of measurementmeter- a unit of length or distance in the metric system of measurement; 1 meter = 100 centimetersHomework-All homework for this week is due on Sunday, April 21.  Monday- Lesson 9.5 Homework and OPTIONAL Chapter 9 Practice TestTuesday- Lesson 9.6 Homework Wednesday- Lesson 9.7 HomeworkThursday- No homeworkFriday- No homework

 Mrs. Walls' Math Blog (Week of 4.8.19)We will begin Chapter 9: Length in Metric Units.  In this chapter, students will learn how to measure using centimeters and meters and also solve problems about adding and subtracting lengths.  Lessons this week include using a concrete model to measure the lengths of objects in centimeters, estimating lengths of objects in centimeters by comparing them to known lengths, measuring lengths of objects to the nearest centimeter using a centimeter ruler, and solving problems involving adding and subtracting lengths by using the strategy draw a diagram.Students will be taking their Mid-Chapter Checkpoint on Friday, April 12.Why teach this?Children have measured in inches and centimeters and have estimated the lengths of objects in inches.  Children will estimate the length of an object in centimeters, based on how it compares to another object for which the length is known.  Children will be shown two objects with different lengths.  The length of one of the objects is given.  Through direct comparison, children first determine whether the object with the unknown length is longer or shorter than the object with the known length.  Then, again using a direct comparison, children estimate how much longer or shorter the object with the unknown length is than the object with the known length.  In this way, children are able to reasonably estimate the whole length of the second object.Chapter 9 Vocabulary-For each chapter, I will be providing a list of important vocabulary words related to our in class learning.  Developing student's math language is a great way to improve their problem solving skills (think of complex word problems!).centimeter- a unit of length in the metric system of measurementmeter- a unit of length or distance in the metric system of measurement; 1 meter = 100 centimetersHomework-All homework for this week is due on Sunday, April 14.  Monday- Lesson 9.1 HomeworkTuesday- Lesson 9.2 Homework Wednesday- Lesson 9.3 HomeworkThursday- Lesson 9.4 HomeworkFriday- No homework
