Measurement
Young scholars use arithmetic in a practical situation using time and distance.
As the calculations involved in this problem involve single digit addition and multiplication it offers a good opportunity to encourage the students's use...
Curated OER
Altitude Tracking
Students construct simple altitude tracking devices for determining the altitude a rocket reaches in its flight. They estimate the altitude a rocket achieves during flight.

Congruent Trianges - Is This Enough Information?
Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.
Curated OER
All About Me
Third graders investigate the use of centimeters while measuring items with rulers which they construct. They examine the need for standard units of measure. They estimate the length of body parts before making the actual measurements.
Curated OER
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"...

How Tall is that Tree?
Students apply their math skills to develop an accurate estimate of the height of a tall tree. Three different methods are outlined. All grade levels should be able to perform the shadow method and the proportional method.
Curated OER
Making Benchmards--Length
Learners explore the idea of having Benchmarks to estimate the length of given objects. Students demonstrate acquired knowledge of the basic units of length by making reasonable estimates. Learners create a personal benchmark.
Curated OER
Balancing Act
Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.
Curated OER
Picking Pythagoras
Students discover that side measurement is used in determining angle classification of a triangle. By squaring sides, they predict whether triangles be right, obtuse, or acute. They prove the Pythagorean Theorem and use it to solve...
Curated OER
How Long? How Wide?
Second graders distinguish between and use nonstandard and standard units of measurement, use appropriate tools and techniques to measure length and width, and record and interpret data using graphs.
Curated OER
How Fast Is Fast?
Students make sensible estimates and check the reasonableness of the answers. Students write and solve problems involving decimal multiplication and division. Students perform calculations with time.
Curated OER
Navigating by the Numbers
Students observe how math is important in navigation and engineering. They study how surveyors use math and science to calcute, count, measure, label, and indicate distances on a map. They estimate specific distances.

Congruent Triangles - Is This Enough Information?
Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.
Illustrative Mathematics
Seven Circles III
A basic set-up leads to a surprisingly complex analysis in this variation on the question of surrounding a central circle with a ring of touching circles. Useful for putting trigonometric functions in a physical context, as well as...
NASA
Launch Altitude Tracker
Using PVC pipe and aquarium tubing, build an altitude tracker. Pupils then use the altitude tracker, along with a tangent table, to calculate the altitude of a launched rocket using the included data collection sheet.
Curated OER
Pirate Plays
Pupils performing a scene about pirates and spend time making a measuring meters incorporating the main character, Captain Blood to add interest. They use meter sticks measuring items from the play and record their answers in meters.
Curated OER
Studying Special Segments in Triangles
Students investigate special segments in triangles. In this geometry lesson, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.
Curated OER
Identifying Lines of Symmetry
Students calculate the lines of symmetry using polygons. In this geometry lesson, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.
