Calculating from Related Addition and Subtraction Facts WORKSHEET DESCRIPTION
Help students build number fluency by exploring how addition and subtraction facts are connected across place value and decimals.
The worksheet begins with simple number sentences such as 11 + 83 = 94 and encourages pupils to use this fact to solve related calculations, including changes in one addend, reversing the order of addition, and switching to subtraction.
As the worksheet progresses, numbers increase in size, decimal values are introduced, and problems extend to larger related calculations.
Enable students to strengthen their mental strategies, develop flexibility in calculation, and deepen their understanding of the relationships between addition and subtraction
