Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
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
Paper Packaging Design
Students discuss the relationship between technology and manufacturing. They then use their ideas to construct a model of a paper board carton package. Next they view a PowerPoint presentation to learn about the history of packaging...
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
Worms and more
Learners have early length experiences must develop an awareness of what length is, and of the range of words that can be used to discuss length. Young children usually begin by describing the size of objects as big and small. They...
Curated OER
Prints and Outlines
Students 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
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
Home on the Range
Students use maps and mathematics to determine the appropriate panther population in a given area. In this Florida ecology lesson, students research the area requirements of male and female panther and use a map to help calculate how...
