SOLID MENSURATION A Message to the Learner

Dear Louisian, In the past few months, numerous things have happened which we did not expect. There are some things that we normally do before which are not possible now. There are also some things that we do not usually do before, but now these things seem to be the new normal. But one thing is for sure, whatever happens, your love for learning will always be there and should not be hampered. So, we, your Math teachers, have prepared a simple module for you. In this module, you will find sample problems with complete and step-by-step solutions, practice exercises, and other activities that will check your understanding of Solid Mensuration. Keep in mind that the more you practice solving, the more you get to understand the lesson. Happy learning! GENERAL INSTRUCTIONS: ✓ Download the module containing CHAPTER 1: Prism and Cylinder.

SUMMATIVE ASSESSMENTS ✓ Summative Assessments are labeled as AssessMath Time. If you have a printer, print the worksheet on a short bond paper, then answer it. If otherwise, on a short bond paper, copy everything including the title of the activity, instructions, given, then your answer. Scan your worksheet or take a clear picture of the entire worksheet and upload it in MS Teams. Please read and follow the GENERAL INSTRUCTIONS FOR SUBMISSION OF WORKSHEET VIA MS TEAMS. The date of submission will be on or before December 9, 2020. FORMATIVE ASSESSMENTS ✓ If you DO NOT HAVE a printer at home, the formative assessments must be answered in your notebook for compilation. It must be labeled following this format: module number, lesson number, the title of the activity, and your answers showing your complete solution (if asked). ✓ If you have a printer at home, you may print the formative assessments on a short bond paper. Compile them in a short brown envelope. ✓ Check your answers in every lesson. A key answer is also provided for you. You may download the key answer or just simply open the file for viewing. Write your scores in your notebook or your printed copy of the worksheet. 1 | Chapter 1. Prism and Cylinder
