Ninth graders produce a projected, pinhole image of the sun and from measurement of the image and projection distance, calculate the actual size of the sun. They estimate the sun's apparent brightness from different planet.

Seventh graders build their own Clinometer and using the tangent of angles, estimate the height of trees. Then these students develop and lesson plan to show whole class and determine the tallest tree on school property.

In this metric measurement of length instructional activity, students find the 4 real objects pictured and estimate the length in centimeters. Students then measure and record the lengths in centimeters or meters.

Here is a very good estimating and measuring length with nonstandard units worksheet. Learners use paper clips and toothpicks to estimate and measure the real objects pictured in each problem, then write ten answers.

Investigate perimeter and area of polygons! For this measurement lesson, learners use index cards to create rectangles and trace their hand to estimate its area and perimeter.

When youngsters are first gaining experience with the volume of solid figures, this is a well-suited worksheet. Nine figures, all made of unit cubes, are drawn for your class to estimate volumes with. Two simple test preparation...

Upper graders explore the topic of volume. In this math lesson plan, pupils count volume in cubic units, multiply to find volume, estimate volume, write a multiplication sentence to find the volume, and make a cost analysis of different...

Upper graders identify the surface area and attributes of figures that are measurable. They estimate, measure, and record perimeter, area, temperature change, and elapsed time, using a variety of strategies. They also determine the...

Youngsters discover the difference between estimating and guessing. They estimate how many items are contained in a jar as they read a story. After the story, pupils discover the differences between estimating and guessing and create a...

Explore the concept of mean, median, and mode with pupils. They estimate the length of a string or the number of M&M's in a jar. Then find the mean, median, and mode of the class' estimates.

You would think that humans make up more mass than ants do on this planet, but think again, and this time by performing calculations. Middle schoolers use scientific notation to compute and compare the estimated total mass of all humans...

Measurement devices can be used to determine the height, length, or weight of all kinds of things, even plants and animals. This presentation acts as the basis for two estimation activities. Each activity requires the children to...

Bring your math class around with this task. Learners simply identify parts of a given circle, compute its radius, and estimate the circumference and area. It is a strong scaffolding exercise in preparation for applying the formulas for...
