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
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
How Many Strips?
Second graders investigate the measurement of 1 meter. They predict and measure how many strips of paper it takes to make exactly one meter. Students devise and use problem solving strategies to solve the problem.
Curated OER
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
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
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
Measuring the Speed of a Wave
Young scholars create an experiment in which they measure the speed of a wave and record the data in a graph. They work in small groups to write the procedure for the experiment and share it with another group for cross checking of the...
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
Perimeters, Patterns, and Conjectures
Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...
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...
