2. Warm-Ups: Decimal Division Last Practice
3. Correct/Collect Page 11 Problem 3 a-d
4, Page 14 Problem #6 a-c

OBJECTIVE: 1.3.3 Describe the location of points on a coordinate grid in any of the four quadrants. 3.1.1 Analyze numerical, measurement, geometric, probability, statistical, and/or algebraic information from a variety of sources. 4.2.2 Represent numerical, measurement, geometric, probability, statistical, and/or algebraic information in graphs or other appropriate forms. 5.1.2 Relate and use different mathematical models and representations of the same situation ACTIVITIES/ASSESSMENT:Decimal division assessment with be a test of decimal devision procedures (tomorrow). This is in the 40% category. Students will work on problem 6 on page 14, incorporating the procedures of central tendency with the graphic representation of data. NOTES: HOMEWORK: Handout: What's the Point D (document your solution)
