WorksheetsWhat this unit covers
Side lengths are the key to telling an isosceles triangle from an equilateral one. Through Finding Isosceles Triangles and Finding Equilateral Triangles among a row of figures, children practice applying the conditions of two equal sides and of three equal sides.
Pulled by how a figure happens to be turned, children skip triangles whose point does not face upward. If only the tilted figures are missing, this is the pattern. Failing to notice that an equilateral triangle also counts as isosceles, and leaving it out of the answer, happens as well.
The topic shifts away from examining the properties of round shapes in Circles and Spheres, and the viewpoint returns here to telling flat figures apart. Grouping shapes by whether they meet a given condition is the method sharpened further under new conditions in Perpendicular and Parallel Lines, Quadrilaterals in grade 4.

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.
