In my experience, students always struggle with remembering when to divide area by two, and when to leave it as just base multiplied by the height. I have discovered that students do MUCH BETTER when they first understand the relationship between parallelograms and triangles, which is the goal of this practice sheet. :)
Students will calculate the area of pairs of parallelograms and triangles that have the same base and height. This helps students to see that the area of a triangle will always be half the area of a parallelogram. I have students work in groups, but you could easily use this as an assessment or homework resource.
