Equivalent+Decimals-+4th+Grade

=Equivalent Decimals- 4th Grade = = by Christie Litchfield = = Grade Level Expectation: Understand and use the connections between fractions and decimals = = Standard: SPI 0406.2.6 Use the symbols <,>, and = to compare fractions and decimals in both increasing and decreasing order.

Prior to this lesson, the teacher will need to create number packets. These packets will be used to review comparing and ordering whole numbers.

**Tools/Supplies: Math Log, Packets ( see above),base-ten blocks ( teacher) ** = Warm-Up- Students partnerships will be given a packet of whole numbers on index cards. Students will order these numbers in increasing or decreasing order per teachers directions. Teacher will check groups as the finish, then allow groups to swap packets and order the next set. = = =
 * 1) The teacher will discuss warm up with students, having students explain strategies for completing task. Students should be using terms greater than or less than in discussion, if not teacher needs to direct conversation back to these terms.
 * 2) Teacher will model comparing decimals using base ten blocks ( 0.4, 0.40 0.20, 0.2, 0.02 1.4, 2.56). Teacher will also model how to write comparisons correctly.
 * 3) Guided Practice - Student will go to Kidspiration. Click on math view, then on base ten blocks. Students will use the base ten block map to compare the following decimals, then write the correct mathematical expression in their math log. ( 0.33, 0.03 0.5,0.50 0.12, 0.1 0.23 0.230 ) . Students will work with partner ( boss/secretary)
 * 4) Independent Practice- Student will complete math activity " Comparing Decimals" in Kidspiration which is located in the math folder under the activities section. After completing the activity students will save their finished work to the desk top. Students should then save work to the system server in the teacher's folder. ( www2.cmcss.net)


 * Extension- Student will go to [|Decimal Comparison Game]
 * If students have not been taught how to save to the server, then students can email teacher the finished product.
