What is a quadrilateral for 3rd grade?
A quadrilateral is a 4-sided two-dimensional shape. There are 4 types of quadrilaterals: parallelograms, trapezoids, rectangles, and rhombuses. ️Parallelograms are quadrilaterals with two sets of parallel sides. A trapezoid is a quadrilateral with exactly one pair of parallel sides.
What is a parallelogram for 3rd graders?
A parallelogram is a quadrilateral with two pairs of parallel sides. Two sides of a shape are parallel if lines placed along them never cross. In a quadrilateral, parallel sides must be opposite sides. This means they do not share a vertex.
What is a rhombus for 3rd grade?

How do you teach a rhombus shape?
To have a rhombus, there are certain things that the shape must have.
- All four sides must be equal, which is why I talked about kicking a square. So a rhombus is like a square in that the sides are all the same length.
- The opposite inside angles are equal.
- The opposite sides are parallel.
