Tasks often involve calculating the perimeter ( ) and area (

Exercises requiring column-style addition and subtraction (up to three-digit numbers) to ensure mastery of standard algorithms. Algebraic Thinking: Basic equations (e.g., Tasks often involve calculating the perimeter ( )

) are used to check the understanding of inverse operations. Tasks often involve calculating the perimeter ( )

Students are asked to solve complex problems involving addition, subtraction, and simple multiplication or division. For example, finding total quantities where one item is more or less than another by a specific ratio or amount. Tasks often involve calculating the perimeter ( )

) of rectangles, as well as converting units of time (minutes to hours) and length (decimeters to centimeters).
