In this worksheet, students roll dice to set the dimensions of rectangles that they then have to find and area and perimeter for. This helps students understand the relationship between these two concepts. This resource is part of a larger unit where students are introduced to the concept of calculating the area of rectangles and triangles, using metric units.
Choose appropriate metric units when measuring the length, mass and capacity of objects; use smaller units or a combination of units to obtain a more accurate measure
Solve practical problems involving the perimeter and area of regular and irregular shapes using appropriate metric units
Recognise ways of measuring and approximating the perimeter and area of shapes and enclosed spaces, using appropriate formal and informal units
Establish the formula for the area of a rectangle and use it to solve practical problems
