General Lesson Information
 Lesson Plan ID: 24176 Title: Estimation Station Overview/Annotation: During this lesson students will learn the difference between estimation and guessing. Knowing how to estimate is an essential skill that will help students determine approximate totals as well as check the reasonableness of their answer to a problem. After listening to the book Betcha by Stuart J. Murphy, the students will be given opportunities to practice the strategies that are presented. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Use various strategies to add and subtract fluently within 1000. Alabama Alternate Achievement Standards AAS Standard: M.AAS.3.10 Using vocalization, sign language, augmentative communication, or assistive technology use concrete materials and pictorial models to model whole numbers. Mathematics MA2019 (2019) Grade: 4 3. Determine and justify solutions for multi-step word problems, including problems where remainders must be interpreted. a. Write equations to show solutions for multi-step word problems with a letter standing for the unknown quantity. b. Determine reasonableness of answers for multi-step word problems, using mental computation and estimation strategies including rounding. Alabama Alternate Achievement Standards AAS Standard: M.AAS.4.1 Solve one-step word problems involving real-life situations using the four operations within 100 without regrouping and select the appropriate method of computation when problem solving.

Local/National Standards:

NCTM Number and Operations Standard Grades 3-5 Compute fluently and make reasonable estimates: Develop and use strategies to estimate the results of whole-number computations and to judge the reasonableness of such results. NCTM Data Analysis and Probability Standard Grades 3-5: Select and use appropriate statistical methods to analyze data Describe the shape and important features of a set of data and compare related data sets, with an emphasis on how the data are distributed. Use measures of center, focusing on the median, and understand what each does and does not indicate about the data set. Compare different representations of the same data and evaluate how well each representation shows important aspects of the data.

Primary Learning Objective(s):

Students will practice their estimation skills and will create a line plot from items which they select and bring to class.

Students will pactipate in activities that will help them to better understand math terms related to data analysis and probability.
