Mathematics – 3

Course Description: In Mathematics 3, 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 100^th; 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.
