Students received their Surface Area & Volume Quizzes back today. Those who score was lower than an 80% were able to make corrections and ask for help during class. The rest of the class worked in the Math Coach Books to help prepare themselves for the CRCT.
HW: none
Introduce students to cross-sections. Please take a look at the websites under the heading Cross-Sections.
HW: Read and try to answer the rest of the What's my Solid? WS
Here are some sites to help you with Cross-Sections.
Made different cross-sections of a cube. http://www.learner.org/channel/courses/learningmath/geometry/session9/part_c/index.html
See examples and definition of cross-sections. http://www.artlex.com/ArtLex/c/crosssection.html

Students took surface area and volume quiz today.
no homework
Students took the Unit 7 Quiz What's my shape?
HW: Holt CRCT workbook p13-18 all Due on Monday!
***No Saturday Tutorial tomorrow (March 22)***
Students completed the measuring and calculations of real world cylinders and rectangular prisms. Tomorrow the students will have a quiz over volume & surface area of rectangular prisms, cylinders, cones, and rectangular pyramids.
HW: Study how to use your formulas
Today we reviewed for the unit 7 quiz that the students will take tomorrow.
HW: Finish pg 727 #1-34 all in the textbook and study for the quiz
Students took real world examples of cylinders and rectangular prisms to find the surface area and volume. Students had to select 2 cylinders and 2 rectangular prisms which they had to measure in inches. Then use their understanding of the formulas to find the surface area and volume of each of their figures.
HW: continue working on the calculations
*Tomorrow the students will need to complete this assignment.
Students used their knowledge of transformations and 2-D figures to make 3-D figures.
HW: textbook p727 #1-34 all This assignment is due Friday, March 21. On this assignment you do not need to show work, just write down the answer to each question. I will be checking for accuracy so make sure your answers are correct.
For help use the following integer rules.
ADDING INTEGERS
SAME SIGN – add # and keep same sign
DIFFERENT SIGN – subtract #and answer will take the sign of the # with the greater absolute value. (Are there more pos. or neg?)
SUBTRACTING INTEGERS – change minus sign to plus and 2nd term to its opposite. Then follow adding integer rules
MULTIPLY/DIVIDE INTEGERS
SAME SIGN – answer is always positive
DIFFERENT SIGN – answer is always negative
Students were given the dimensions of a cylinder, cube, rectangular prism, cone and pyramid. Then they had to find the surface area (only of the cylinder, cube, & rectangular prism), the volume (all shapes), and draw the figures nets. Students were given a copy of the list of formulas that they will have on the CRCT to help them complete this task.
HW: To complete this assignment. Students were also asked to bring in an example of a cylinder, or cube, or rectangular prism, or cone, or pyramid. The more the merrier.
