Measuring+in+Non-standard+Units+with+CompassLearning+(2nd+Grade)

by Mike Haskins and Chris Pugh

=Standards=
 * Math**
 * CFU 0206.4.5** - Use rulers to measure the lengths of sides and diagonals of common 2-dimensional figures and polygons.
 * GLE 0206.4.2** - Understand the meaning and process of linear measurement.


 * ISTE NETS** **6a.** **Technology Operations and Concepts** - understand and use technology systems.

=Lesson= Before the lesson, the teacher will need to download the desktop icon to the student laptops for CompassLearning in our district. The teacher will also need to clear a space in the floor in front of the document camera for modeling measurement. Use the FREEZE feature of the LCD projector to freeze the image, if the students are getting too excited with their picture from the projector.

TSW...
 * 1) Double -click on the icon for CompassLearning Odyssey. It should open in Safari.
 * 2) Have the students login with their username and password.
 * 3) Creating the "Rules for Measuring".
 * Click on the Odyssey Writer icon on the left hand side. It looks like a piece of paper with a pencil.
 * Resize the font from 12 to 24.
 * Type "Rules for Measuring".
 * Hit RETURN key twice.
 * Type "1." ( The teacher will pick 2 students from the class. One will lie in the floor in front of the teacher cart with the document camera rotated to point at them. The other walk heal to toe beside the other student to measure with their "feet". The teacher will measure the student in the floor with their feet. When the numbers don't match, have the students figure out why and write the first rule for measuring.)
 * Hit RETURN key twice.
 * Type "2." (The teacher will call another pair of students to lie down in the floor to get measured. This time the teacher will ask a third student to be the "one size" measuring person for both, but will ask that person to measure both at the same time. When it can't be done because 1 person can't measure 2 things at the same time, have the students come up with rule number 2.)
 * Hit RETURN key twice.
 * Type "3." (The teacher will call another pair of students. One will lie in the floor in front of the teacher cart with the document camera rotated to point at them. The other walk heal to toe besidethe other student to measure with their "feet". The teacher will have the measurer start and measure starting at the knee one time and then starting at the feet of the person in the floor for the second time. When the students figure out why the numbers don't match, record their solution as rule number 3.)
 * Hit RETURN twice.
 * Type their name and PRINT. (The teacher may also choose to have them SAVE their rules into CompassLearning. They can be accessed later by using the FILE and OPEN in the OdysseyWriter.)
 * 1) Using the "Rules for Measuring".
 * Once the student's have logged into CompassLearning, click on the icon for the MATH TOOLKIT.
 * Click on the yellow MATH button.
 * Click on the GEOBOARD. (For teachers, login to CompassLearning, go to the CONTENT tab, click RESOURCES, then MATH TOOLKIT, and finally click GEOBOARD.)
 * Click on a colored rubber band from the left. The color can be changed by clicking the color blocks below the virtual rubberband icon.
 * Click on a peg to place the rubber band on the geoboard.
 * Move your cursor to touch the rubberband, then click and drag the to another peg to stretch it.
 * Repeat the stretching until you have built a polygon.
 * Use the spaces between the pegs as non-standard units of measurement.
 * For standard units of measurement, click the ruler tool from the left. The 45° button rotate the ruler quickly. The other 2 arrow buttons rotate it slowly either clockwise or counterclockwise.
