WorksheetsWhat this unit covers
Attention turns to the relationship between two straight lines, beginning with Finding Perpendicular Lines and Finding Parallel Lines. After parallel lines and angles and The Width Between Parallel Lines, trapezoids, parallelograms and rhombuses are picked out by label, and the properties of diagonals follow in one continuous thread.
Trying to tell a parallelogram from a rhombus by equal side lengths alone leads to mixing the two up, and this is also where answers that refuse to count a square as a rhombus come from. With diagonals the two properties get swapped: a rectangle has diagonals of equal length, while a rhombus has diagonals that cross at right angles.
The skill for calculating vertical angles built in Angles is put to work on the angles formed by a pair of parallel lines, and from there this unit teaches how to tell a rhombus, a parallelogram and a trapezoid apart. This grasp of a shape's defining traits leads straight into Area in grade 5, which asks for the area of a parallelogram or a rhombus to be calculated directly.

A pointed corner facing sideways is enough for a child to say, "that's not a triangle." It's a sign they've learned shape names by overall look rather than by their properties. Here's how to teach children to tell shapes apart by the number and length of their sides, in order from grade 2 through grade 4.
