When the tape measure will not reach, use similarity. An installment of a large playlist on geometry introduces the method of indirect measurement. Using a story of finding the distance to the sun, the video shows how to use similar...

Geometry—it's not just for the math classroom! Learners explore the field of forestry through a mathematical lens. An instructional resource explains how forest workers collect data about trees such as height, diameter, and age using...

How did ancient peoples determine the height of really tall objects? Young scientists and mathematicians explore the concept of using shadows to measure height in a hands-on experiment. Paired pupils measure shadows, then calculate the...

Conduct indirect measurements three ways. Working in groups, pupils come up with different ways to measure three tall objects indirectly. The teacher provides measurement information requested by the teams, and learners then calculate...

Two similar triangles have the same angles, but their legs have different lengths. This means their angles are congruent, and thusly, their corresponding sides are congruent. So there is a missing measurement that needs to be found. Set...

Look up or down to find the answer.  A segment of an extensive playlist on geometry introduces angle of depression and elevation to find indirect measurements. Using trigonometric ratios, the presentation finds missing sides and angles...

Your hand can be a handy tool for measurement. Young mathematicians learn how to estimate the height of objects by applying similarity. They find the horizontal distance from the object where spreading their outstretched fingers results...

In this shadow sleuth activity, students use proportions and indirect measurement to determine the measurement of given objects. This one-page activity contains three problems.

Students compare the weight of the students's favorite soft toys directly and then indirectly using beads.

Students measure distances using indirect measurements. In this geometry lesson, students apply proportion and ratios to measure heights of different objects. They differentiate between direct and indirect measurements.

Students explore the necessity for standards of measurement and measure length, volume, mass and angles. In this measurement lesson plan, students use their hand and foot to measure objects in the room. They compare their measurements to...

Although the graphics on this length comparison exercise aren't great, pupils will get the idea. They read an indirect length word problem, which asks them to compare three animals from shortest to tallest. The wording here may be...

Word problems are a wonderful way to connect math and the real world. However, I've never seen a 12 centimeter-long apple tree. Aside from some odd word choices, this worksheet provides children with ten problems to solve by determining...

In this geometry worksheet, students differentiate between direct and indirect measurements. They create a table with their findings. There are 9 questions.

Find the height from afar. Teams role play as summer interns to find the height of a set of windows from the outside. Scholars must first determine how to find the height with the available tools. After determining a strategy involving...

Young scholars measure and apply their knowledge of proportion to solve problems. In this geometry lesson, students measure using a meter stick, small mirror and measuring tape. They compare and contrast their measurements to objects...

Measuring the diameter of the sun may get a little heated, but using an indirect approach can help individuals keep their cool. Learners use the reflection of the sun to measure how long it takes for it to move one diameter. Using the...

Student form and test hyptheses using indirect and direct observation. They launch marbles to determine the shape of a hidden object.

How do you find the lengths of items that cannot be directly measured? The 13th installment in a series of 16 has pupils use the similarity content learned in an earlier resource to solve real-world problems. Class members determine...

Students investigate the concept of measurement for capacity and they use real containers to be filled of different sizes. Students use the scoops as the number of units for counting the capacity volume. Then they order the containers by...

Ninth and tenth graders calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They solve problems involving scale drawings, models, maps or...

Students use similar triangles to find missing heights.  In this using similar triangles to find missing heights lesson plan, students use proportions to find the heights of missing side lengths.  Students find the height of trees and...
