Using indirect measurement, this video shows viewers how to find the height of a flagpole. The lecturer employs drawings as well as proportions to solve this problem, explaining each step. A useful resource to aid struggling learners and...

Using indirect measurement, this video shows viewers how to find the height of a flagpole. The lecturer employs drawings as well as proportions to solve this problem, explaining each step. A useful resource to aid struggling learners and...

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...

Working as a landscape architect, your designers calculate the measurement of the school flagpole as a guide to picking the right trees for their plan. Using indirect measurement with proportions, the goal is to calculate how high they...

In this measurement of area worksheet, 7th graders identify and complete 5 different problems that including determining the measurement of an area in a shamrock figure. First, they determine the area of the shamrock illustrated by...

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...

Eighth graders explore indirect measurement.  In this elementary mathematics lesson, 8th graders use shadows and the concept of similarity mirrors to see reflected images and use a stadia to conduct indirect measurement.  The lesson...

Learners measure the flag pole using indirect measurement. In this geometry lesson, students use the properties of geometry and indirect measurement to landscape properties. They relate indirect measurement to architecture and landscaping.

Students solve indirect ratios.  In this indirect measurement lesson, students explore trigonometric functions and ratios using outdoor objects.  They estimate heights and  perform indirect measurements.

How do you measure a distance where the measurement tool will not reach? Pupils use the concept of similar triangles to perform indirect measurements. The lesson asks teachers to demonstrate the method and lead the class through a set of...

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...

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.

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

Proportional reasoning, ratio, and indirect measurement come to life in a series of seven lessons. Learners will convert measurements into customary and metric units. They also use real-world examples to solve problems involving scale as...

Students measure distances using indirect measurements. For 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...

Students use similar triangles to solve a real-world problem.  In this geometry lesson, students explore properties of ratios and proportion as used in similar triangles and use proportions to determine the indirect height of an object. 

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...

Eighth graders investigate direct and indirect measurement.  For this eighth grade geometry and measurement lesson, 8th graders investigate a variety of methods for measuring the height of a tree.  Students investigate and use the...

Which method results in a better estimate of the height? Using  different methods, groups estimate the height of three objects on campus. They record their measurements and any necessary computations and compare them to the actual...
