Tenth graders answer a variety of problems based on similar triangle and learn about the rule of thumb. They will test the rule of thumb by estimating the distance to an object in the classroom.

Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.

Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.

Learners observe and sort tree leaves. In this plant biology lesson, students observe various types of leaves and identify the characteristics of each leaf. Learners measure and sort leaves according to size and color.

In this problem-solving skills worksheet, students learn how to determine whether or not an estimate is enough when solving a problem. They then use this skill to solve the 2 questions at the bottom of the page.

Students explore the idea of having Benchmarks to estimate the length of given objects. Students demonstrate acquired knowledge of the basic units of length by making reasonable estimates. Students create a personal benchmark.
