PART 1: SELECTING AND SETTING UP A MATHEMATICAL TASK (PREPARE) What are your mathe m a t ical g oals Use decimal notation for fractions with denominators 10 or 100. for the lesson? (i.e., what do you want students to know and understand about mathematics as a result of this lesson?)

 What are your expecta t ions for  Students will understand that decimals are special types of fractions that can be written with a students as they work on and denominator that is equal to 10 or 100. complete this task?  Students can write decimals using digits and write the equivalent fraction.  What r esou r ces or tools will students have to use in their  Tools: paper, pencil, grid paper, rain gauge, weather log, base 10 blocks, place value chart, work that will give them fraction bars and decimal bars entry into, and help them  Small group reason through, the task?  Students will collect data  How will the students work—  Students will record their data on graph paper, choosing how they wish to represent their data independently, in small groups, or  Groups will present their data and results in pairs—to explore this task?  How will students record and report their work?

How will you introduce students to the LAUNCH (5-15 minutes) activity so as to provide access to all *Watch the Bill Nye film: “The Water Cycle” on You Tube. students while maintaining the cognitive demands of the task? *Have students make rain gauges using the following web site: www.ecokids.ca/pub/eco_info/topics/climate/weather/page4.cfm * Collect and record rainfall data in fraction form in weather logs.

1. Measure your rainfall in millimeters and centimeters and record in your weather log.

2. List the rainfall data recorded in your weather log on your chart.

3. Using your tools, convert and record the fractions to decimal form.

4. Create a graph showing your data in fraction and decimal form.

5. Explain and demonstrate how you converted your data from fraction to decimal.

Extension: 1. Convert your cloud cover data from fraction to decimal and record on your chart. 2. Make a line plot to display your data in fractions. Domain/Standard Code: 4.NF.6 Author Name: Grand 4th Page 4 Title of Task: _____Converting Rainfall Data from Fraction to Decimal Form______

PART 3: SHARING AND DISCUSSING THE TASK (DISCUSS/DEBRIEF 10-25 minutes) How will you o r c h es t r a te the class d iscussion so that you accomplish your mathematical goals?  Which solution paths do you want to have shared during the class discussion? In what order will the solutions be presented? Why?  What specific questions will you ask so that students will— 1. make sense of the mathematical ideas that you want them to learn? 2. expand on, debate, and question the solutions being shared? 3. make connections among the different strategies that are presented? 4. look for patterns? 5. begin to form generalizations?

What will you see or hear that lets you know that all students in the class understand the mathematical ideas that you intended for them to learn?
