Curated OER
The Great Cover Up!
Students use non-standard measurement tools such as body parts, beans and counters to find the area of shapes drawn on the floor. They continue to determine the area of other objects in the classroom.

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
Weights
Young scholars 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
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
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
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
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
Worms and more
Students 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
How far is a km?
Students 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
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
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
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
Let's Measure
Third graders practice measuring different objects. They discover the concepts of ratio and proportion and practice converting numbers into the correct unit. They read stories as well to help them with the concepts.
Curated OER
Relative Weight
Second graders distinguish the difference between pounds and ounces and arrange manipulatives from heaviest to lightest.
Curated OER
Place Value: Metric System
In this metric system worksheet, students read about metric and place value relationships, examine some sample problems, and then complete 5 conversion charts.
Curated OER
A Fashion Extravaganza
Students decide what body measurements they need to make garments such as a pair of pants. They make a list, and work with a partner to take and record those measurements in centimeters. They discuss the use of centimeters.
