MATHEMATICS – 2

SECOND QUARTER

Course Description: The learners demonstrate understanding and appreciate of key concepts and skills involving numbers and number sense ( whole numbers up to 1 000, ordinal numbers up to 20th, money up to PhP 100, the four fundamental operations of whole numbers, and unit fractions ); geometry ( Basic shapes, symmetry, and tessellations ); patterns and algebra ( continuous and repeating patterns and number sentences ); measurement ( time, length, mass and capacity ); and statistics and probability ( tables, pictograph, and outcome ) as applied – applied – using appropriate technology – in critical thinking, problem solving, reasoning, communicating, making connections, representations and decisions in real life.

I. Objectives: At the end of the quarter, the learners will be able to:

A. apply addition of whole numbers up to 1 000 including money in mathematical

problems and real – life situation;

B. . visualizes, represents, and subtracts 2- to 3-digit numbers with minuends up to 999

without and with regrouping;

C . subtracts mentally 1-digit numbers from 1- to 3-digit numbers without regrouping

using appropriate strategies;

F. performs orders of operations involving addition and subtractions of small numbers;

G. illustrates multiplication as repeated addition

H. writes a related equation for each type of multiplication: repeated addition, array,

counting by multiples, and equal jumps on the number line;

I. illustrates the property of multiplication that any number multiplied by one (1) is the

same number;

J. illustrates the property of multiplication that zero multiplied by any number is zero;

K. illustrates the commutative property of multiplication;

L. visualizes multiplication of numbers 1 to 10 by 2,3,4,5 and10;
