Scaling Our School
Fourth graders practice estimating the length and height of buildings at their school. They then compare their estimations with the actual heights or lengths. Each student then builds a scale model using ratio to translate the "real"...
Curated OER
One Size Fits All?
Learners describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...
Curated OER
Quilt Squared
Students study West Virginia quilts. For this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.
Curated OER
Geoboard Squares
Learners create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...

Determine Volume of Solids Using Water Displacement
Students explore math functions by completing math equation worksheets. In this inequality instructional activity, students define a list of math terms and discuss the difference between an equation and inequality. Students utilize a...
Curated OER
How Tall Is That Flag Pole?
Students examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.
Curated OER
Partial Products
Third graders study partial-products algorithms. In this math activity, 3rd graders use an algorithm to find the product of factors. Students discuss the relationships between multiplication and division.
Curated OER
Geometry in Nature
Students examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

The Miracle Fish: Learning to Design an Experiment
Young scholars develop procedures to explore the behavior of fish. In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment.
Curated OER
Paper Planes
In this unit, 3rd graders investigate one variable to see if they can make a paper plane fly farther. They use scatter plots to establish a possible relationship between variables then use what they have found to make a paper plane to...
Curated OER
Properties of Soil
Fourth graders conduct investigations to test different types of soil from different regions of Texas. They make comparisons and identify the characteristics of the soil. The end product of the inquiry is a student report.
Curated OER
Literal Equations
Students explore Literal Equations. In this literal equations lesson plan, students use the Internet to connect to links and solve linear equations. Students investigate, analyze and record their findings on various activity worksheets.
Curated OER
How Hot Is It?
Fourth graders practice estimating temperatures. They practice in Celsius and Fahrenheit.
Curated OER
A Real Difference
Fifth graders use the Celsius and Fahrenheit thermometers to compare temperature readings. They use the Internet to find the temperatures of selected cities. After data is collected for five days, 5th graders graph the temperatures.
Curated OER
Relationships and Functions
Fifth graders describe patterns as relations and functions. In this patterning lesson, 5th graders analyze and continue patterns. Students understand how patterns relate to relations and functions.
Curated OER
How much room?
Students examine the amount of usable space that exists in their classroom using square meters and square centimeters. They apply the information to predict the ideal size of a classroom.
Curated OER
Marshmallows
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.
Curated OER
Waste Audit
Students engage in a lesson that is concerned with the concept of mental math. They perform calculations as following: recognizing a half, three quarters, and tenths. Students are also challenged to extend skills to making calculation...
Curated OER
Houses
Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...
Curated OER
Two Ways About It
Students take an imaginary hike in two opposite directions along a lake. They view and interpret satellite images and discuss the pros and cons of hydroelectric dams.
Curated OER
A thousand seconds
Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.
Curated OER
Parking Meters
Third graders are introduced to the problem with a short discussion about parking. They then solve with a partner. As they work ask questions that focus on the strategies they are using to make the calculations.
Curated OER
Garry The Greengrocer
Fourth graders are introduced to the problem by weighing objects on the balance scales. Use weights in both pans. (If you don't have access to scales use 2 containers and a child acting as the balance.) They then listen to the problem...
Curated OER
Adam's Watch
Third graders use their watches to tell the time while the teacher lists their responses on the board along with the reasons for them (set incorrectly, gain/lose time). They solve the problem in pairs and focus their thinking on the...
