Calculating with Bounds WORKSHEET DESCRIPTION
The "Calculating with Bounds" worksheet focuses on rounding and working with bounds. In Section A, students calculate the upper and lower bounds for different values of x and y, therefore applying the four operations whilst building familiarity with bounds through straightforward arithmetic.
Section B then advances into finding the upper and lower bounds of the perimeter and area of various polygons, encouraging students to apply bounds to geometric figures.
Section C brings in real-world scenarios, calculating bounds for compound measures such as speed and density.
Sections D and E challenge students with more advanced problems, involving bounds in algebraic expressions and compound calculations.
