Projection Enlargements of Objects

Today we finished the Shrink Art activity, and then turned our attention to enlargements. We used the document camera and the projector to determine the enlarged size of things. We discovered that the distance between the projector and the surface your project your objects on does make a difference.

Tonight's Homework: Determine the enlargement ratio of the data you collected in class today. Graph the data and write equations for the three lines.

Test over Surface Area and Volume Taken in Class Today

Because we have finished the unit on surface area and volume, students were given time in class to show their proficiency by taking the unit test.

Tonight's Homework: None. Enjoy the weekend!

Shrink Art, One More Time!

After reviewing answers to last night's homework, we went over specifics about Friday's test. Specifically, students will have access to formulas, and will be able to use calculators. Of course, work will need to be shown! (This is test over finding the surface area and volume, NOT how to multiply and divide, so calculator use is certainly permissible.)

Tonight's Homework: Complete the pink worksheet if you were unsure of how to do the ratio part of it. Be ready to transfer your picture to the plastic if you haven't already done so. Shrinking will take place tomorrow in class.

More on Surface Area and Volume of Spheres, Cones and Pyramids

Students reviewed how to find the surface area and volume of spheres, cones and pyramids by working in groups to answer a series of questions related to real life situations.

Tonight's Homework: Complete the problems on the pink worksheets that you did not finish in class today.

Happy Earth Day!

Students received stickers and bookmarks to commemorate earth day. We also enjoyed treats to celebrate our terrific results on the state math test. We learned how to figure out the surface area and volume of spheres, and tried to make sense of the formulas using pictures.

Tonight's Homework: Home Book, pages 74-75 ( 4 - 15 ).

Round One of OAKS Math Testing is Complete

Students completed the last portion of the state math test today in class. The scores were phenomenal, and a tribute to the hard work, dedication, and determination of all who took the test. I couldn't be prouder of you!

Tonight's Homework: Complete the brown integer computation worksheet if you didn't do so in class today. It's due on Monday, 4/22.

Day Two of OAKS Math Testing is History!

Students completed the next portion of the state math test today in class. While most students took their time to complete the next 15 problems on the test, some were able to finish the test today. The majority of the class will complete the test tomorrow, and I'm hoping most, if not all, students will be pleased with their results. Cross your fingers!

Tonight's Homework: Be sure to get enough rest tonight, and come back refreshed and ready to finish taking the state test!
