Curated OER
Time Zones
Students are able to read and also use a variety of timetables and charts. They perform calculations with time, including 24-hour clock times and time zones. These are very important concepts that Students probably have to bear in mind...
Curated OER
Cool Times with Heat
Learners work with thermometers to complete problems about temperature. They investigate cooling patterns, how location affects temperature, and what happens when water having different temperature is mixed. They measure temperature in...
Curated OER
Simple Angles
Third graders identify and construct right, acute and obtuse angles and begin to appreciate the degree and unit of measurement of angle. They know the degree value of angles that are simple fractions of a whole turn know that the angle...
Curated OER
Party Volumes: Measurement
Second graders explore liters and milliliters. They estimate volume and accurately measure the volume. Students plan a party and measure volume using liters and milliliters as part of the planning process.
Curated OER
Supermarket Shopping
Students participate in studying that a kilogram is a standard unit of measurement. They measure practical objects using length, mass, and capacity. They measure a number of supermarket items using units and scales.
Curated OER
Oranges and Stopwatches
Students measure various attributes of an orange. They discuss the attributes of an orange that can be measured, develop a list of attributes and describe how they can measure it, and rotate through four stations measuring the volume,...
Curated OER
Boxing On
Students participate in five center activities in which they construct three dimensional objects using cubic centimeter manipulatives such as sugar cubes and toothpaste boxes. They determine the volume of the objects. They build a model...
Curated OER
Using A Ruler
Students investigate the concept of measurement and using a ruler with accuracy up to 1/16 of an inch. They practice using measurement with a ruler in different contexts. To help with the presentation of the lesson a PowerPoint slideshow...
Curated OER
Sampling Rocks
Pupils study rocks they find on the playground. In this investigative lesson plan students collect and analyze rocks they find and answer questions about them.
Curated OER
Soggy Seeds
Students conduct experiments to learn about seed germination. In this seed germination lesson, students write a hypothesis for the seed experiment. students complete the experiment for seed germination and graph the data obtained from...
Curated OER
Sports Helmets and Impact Testing of Polymers
Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...
Curated OER
Average Looking
Students use measurements of their classmates to find the average (means and modes) of their facial features. They use their findings to create a three-dimensional "class head." Examples and assessment materials are included.
Curated OER
Squirt
Fourth graders using the idea of "how many more squirts" fill a container to develop multiplicative thinking. They also investigate the idea of conservation of volume when working with oddly shaped containers. They attempt to use...
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
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...
Curated OER
Emulsion_ Compulsion
Middle schoolers experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.
Curated OER
Make a Zoo
In this unit students work in groups to find out about an endangered animal species. They design a zoo enclosure for the animal and build a scale model. Together the class constructs a zoo! In the process of planning and building the zoo...
Curated OER
How far is a km?
Young scholars explore the size of a kilometer and the time it takes to cover this distance. They develop a concept of a km. They measure a distance of 1 km and the time taken to cover it.
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
Oranges and Stopwatches
Students begin to recognize that objects have many measurable attributes. They examine how to identify and accurately measure attributes of common objects. Also Students report their measurement findings.
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...
