Investigating the Idea of Tan
Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

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
Weights
Students find an object that they estimate weighs 20g and check estimates on the balance scales. They read the problem and work in pairs focusing their understanding on the size of grams.
Curated OER
Parallax
High schoolers discover how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of some stars, and the meaning of "Parsec" and "light year."
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...

Polygons Defined
Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.
Curated OER
Hidden Jewels of Geometry
Students identify different geometric shapes, and arrange them artistically in original jewelry designs.

Design Your Space
Learners evaluate the acceptable use of classroom space. The class participated in a brief lecture and discuss of floor plans and how they are used in architecture. Using graph paper, they create a scale drawing of the classroom...

Rice (Gohan) Observations
Second graders investigate rice or gohan as it's called in Japan in a couple of experiments. They tally the results.
Curated OER
Prints and Outlines
Learners determine the area of two objects by superimposing one on the other. They compare and order the area of different shapes by covering a larger shape with similar smaller ones. They complete these activities as different stations.
Curated OER
Visiting Grandma
First graders investigate the aspect of time, including days of the week using a calendar. They use problem solving strategies and a monthly calendar to find a solution to the problem.
Curated OER
A thousand seconds
Pupils 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...

The Architectural Style of Frank Lloyd Wright
Young scholars explore the qualities of tangible and intangible using the architecture of Frank Lloyd Wright. After a brief introduction of the vocabulary, they use the internet to research the architecture of Frank Lloyd Wright. Once...
Curated OER
Friction- What a Drag
Students explore friction. For this friction lesson, students investigate that weight and surface type affect friction.
Curated OER
Clocks and Time
Students construct clocks and then learn how to read a clock face, tell time, and determine how much time has elapsed.
Curated OER
Seein' Double, Seein' Double
By using the Internet, hands-on activities, video, and cooperative learning, pupils look into the conditions in which light casts shadows on objects. The lesson includes fabulous hands-on activities, art projects, worksheets, and reource...

Gravity (Newton's Laws of Motion): A Weighty Subject
Students identify Newton's Laws of Motion. They students explore Newton's Laws of Motion and apply the second law with a classroom activity. The videos will provide visual examples of the effects of gravity while riding on a roller coaster.
Curated OER
PLANETS IN PROPORTION
Students discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl reasoning to...
