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. creates problems involving subtraction of whole numbers including money;

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

C. illustrates multiplication as repeated addition

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

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

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

same number;

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

G.  illustrates the commutative property of multiplication;

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

I. creates problems involving multiplication only and multiplication with addition or

subtraction of whole numbers including money with reasonable answers;

J. visualizes and represents division as equal sharing, repeated subtraction, equal jumps on the number line and using formation of equal groups of

objects;

K. creates and writes a related equation for each type of situation: equal sharing, repeated subtraction, equal jumps on the number line, and

formation of equal groups of objects,

L. visualizes division of numbers up to 100 by 2,3,4,5, and 10 (multiplication table of 2, 3, 4, 5 and 10;

M. divides mentally numbers by  2,3,4,5 and 10 using appropriate strategies (multiplication table of 2, 3, 4, 5 and 10;

N. illustrates that multiplication and division are inverse operations;

O. solves routine and non-routine problems involving division of numbers by  2,3,4,5 and 10 and with any of the other operations of whole

numbers including money using appropriate problem solving strategies and tools;

P. creates word problems involving division of whole numbers including money;

Q. visualizes, represents and identifies unit fractions with denominators of 10 and below;

R. reads and writes unit fractions;

S, compares unit fractions using relation symbols;

T. arranges unit fractions in increasing or decreasing order;

U. identifies other fractions less than one with denominators 10 and below;

V. visualizes similar fractions (using group of objects and number line);

X. reads and writes similar fractions;
