CK-12 Foundation

#### Indirect Measurement: Lesson

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...

Open Oregon Educational Resources

#### Forest Measurements: An Applied Approach

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...

#### Measuring Shadows Using an Ancient Method

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...

Radford University

#### REALLY Tall!

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...

#### How Do You Find Missing Measurements of Similar Figures Using a Proportion?

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...

CK-12 Foundation

#### Trigonometry Word Problems: Lesson

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...

Exploratorium

#### Handy Measuring Ratio

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...

Curated OER

#### Countdown Challenge: Shadow Sleuth

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

Curated OER

#### Measuring Beads

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

Curated OER

#### Indirect Measurement, Surveying Trigonometry

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

Curated OER

#### Measurement

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

Curated OER

#### Indirect Length Word Problem

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...

Curated OER

#### Indirect Length Word Problems

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 instructional activity provides children with ten problems to solve by...

Curated OER

#### Indirect Measurement

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

Radford University

#### How Tall Is It?

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...

Curated OER

#### Indirect Measurement

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

Las Cumbres Observatory

#### Measure the Diameter of the Sun

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...

Curated OER

#### Indirectly Direct

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

#### Modeling Using Similarity

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...

Curated OER

#### Measuring With Fluids

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...

Curated OER

#### CORNER CABINET

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...

Curated OER

#### Indirect Measurement with Similar Triangles

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