Order of Fractions

In this module, fraction strips serve as springboards for comparing fraction sizes and ordering fractions. Other than ordering fractions by modeling, fractions are compared by expressing the fractions as similar fractions using the LCD or the Least Common Denominator.

Perimeter of Quadrilaterals

This module presents the concept of the perimeter of common quadrilaterals, namely square and rectangle. It shows how the perimeter of a rectangle is derived using its length and width; and that the perimeter of a square is derived using the measure of a side. It also includes problems that require solving for the missing part (say L or W) when the perimeter and a side are known.

Volume

This module presents the method in finding the volume of a rectangular prism by the discovery approach. Problems involving determining the number of cubic units without actually counting the cubic units, are expected to pave the way to the discovery of the rule for the volume of a rectangular prism.

Comparing Fractions

This is a module on comparing fractions. It introduces the fraction chart as a means to compare common fractions. It involves comparison of fractions with the same numerator, fractions with the same denominator, and fractions that do not have the same numerator and denominator. Likewise, it presents the greater than (>) and less than (<) symbols to compare fractions. It also presents a method in arranging fractions from smallest to greatest and vice-versa.

Area of a Parallelogram

This module is about deriving the formula for the area of a parallelogram from the knowledge of the area of a rectangle. A working knowledge of the concept of the area of a parallelogram is enhanced by a series of exercises that require the pupil to find the area of a parallelogram when the base and height are given, or find the base or height when the area and any one of base or height is given.
