MATHEMATICS 3

SECOND QUARTER

Course Description: The learners demonstrate understanding and appreciation of key concepts and skills involving numbers and number sense ( whole numbers up to 10 000; ordinal numbers up to 100th; money up to

PhP1 000; the four fundamental operations of whole numbers; proper and improper fractions; and similar, dissimilar, and equivalent fractions ); geometry

 ( lines, symmetry, and tessellations );patterns and algebra ( continuous and repeating patterns and number sentences ); measurement ( conversion of time, length, mass and capacity, area of square and rectangle ); and statistics and probability ( tables, bar graph, and outcome ) as applied – using appropriate technology – In critical thinking, problem solving, reasoning, communicating, making connections, representations, and decisions in real life.

                     L.  estimates the product of 2- to 3-digit numbers and 1- to 2-digit numbers

                          with reasonable results;

                     M.  multiplies mentally 2-digit by 1-digit numbers without regrouping with

                          products of up to 100;

                     N. solves routine and non-routine problems involving multiplication without

                          or with addition and subtraction of whole numbers including money

                          using appropriate problem solving strategies and tools;

                     O. creates problems involving multiplication or with addition or subtraction

                         of whole numbers including money;

                     P. visualizes division of numbers up to 100 by 6,7,8,and 9 (multiplication

                          table of 6, 7, 8, and 9);

                     Q. divides 2- to 3-digit numbers by 1- to 2- digit numbers without and with

                          Remainder;

                     R. divides 2-3 digit numbers by 10 and 100 without or with remainder;

                     S.  solves routine and non-routine problems involving division of 2- to

                          4 – digit numbers by 1- to 2-digit numbers without  or with any of the  

                         other operations of whole numbers including money using appropriate  

                         problem solving strategies and tools.     

                            T. creates problems involving division or with any of the other operations      

                          of whole numbers including money.
