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
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
Points
Students listen to Gill's story and determine how many number points she has. They then find the number of points their own name has and get into groups where all the name points are the same.
Curated OER
Lots of Squares
Students work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.
Curated OER
Triangular Numbers
Students are introduced to the problem and brainstorm ideas for approaching the problem and keeping track of what has been done. They work in pairs and share their answers, explaining their reasoning.
Curated OER
The Topsy-Turvy Twins
Fourth graders read the problem and brainstorm for ways to solve the problem - list these on the board for the students to refer to as they solve the problem. They work in pairs and focus on the strategy selected.
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
The Chicken Run
Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...
Curated OER
Noughts
Students try to figure out the strategies to the game Noughts. Students logic must play a part in the process of the game. Students apply the symmetries of regular polygons. Students devise ways to critically follow a chain of reasoning.
Curated OER
A4 Containers
Fifth graders determine which container made from a single sheet of paper has the greatest volume. They look the solutions made by three different students before working on their own examples.
Curated OER
Jackson's Consecutive Numbers
Young scholars generate patterns from a structured problem, finding a rule for the general term, and expresses it in words and symbols. They then devise and use problem solving strategies to explore situations mathematically.
Curated OER
Time Problems
High schoolers make sensible estimates and check for reasonable results. They also solve problems with positive and negative integers using practical activities or models as needed.
Curated OER
Adding Ten Tiles I
Students practice this problem that needs a certain amount of experimentation (trial and error) to get any answer at all. In the process they practice their basic number facts. However, to get the complete set of answers Students need to...
Curated OER
From a Square to a Rectangle
Eighth graders solve problems involving percentage increases and decreases. Using given percentages, 8th graders transform a square into a rectangle. They apply the area formulas for squares and rectangles.Students observe the percent...
Curated OER
No-Three-In-A-Line Again
Students interpret information and results in context while using words and symbols to generalize patterns. They use symmetry and angle properties of polygons to solve practical problems and identifying invariant properties under...
Curated OER
Connecticut Folklore: Fact or Fiction
Sixth graders read legends to learn the history of Connecticut in a fun informative way.
Curated OER
Different Ethnic Groups in Ecuador, Panama and Argentina: Their Assimilation and their Contributions
High schoolers research various Latin American countries and reflect on the different ethnic communities represented in that country and their contributions to the region. They make posters, perform skits and write letters about their...
Curated OER
In Conclusion
Fifth graders practice identifying the conclusions they can draw using the "In Conclusion Introduction" story which is attached. They complete a Conclusion worksheet which is attached.
Curated OER
Rhyme Time
Second graders write poems based on locomotive skills, such as hop, skip, or run. They read their poems to the class and they act out the action word by performing it to a finish line.
Curated OER
Where Do We Go?
Students participate in a physical activity while they utilize terms and vocabulary related to chronology and location.
Curated OER
Construct Figures to Find Specific Volume
Sixth graders use number cubes to explore volume of two-dimensional shapes. They roll a die and construct a shape using the numbers rolled as measurements of the sides. They estimate the volume of a given object, and then use the...
Curated OER
The Part-adder 1
Second graders investigate the addition of whole numbers. They mentally perform calculations involving addition and subtraction. They make sensible estimates and check the reasonableness of answers.
Curated OER
Scavenger Hunt
Second graders participate in a Scavenger Hunt to find out how long 1 cm is. They then find 10 objects that estimate to be 1 cm in length and record their findings on the table provided and check their estimates using a ruler.
Curated OER
Around We Go
Fourth graders investigate a range of circles, each with a different radius, diameter and circumference and assemble this information in their search for relationships.The measurement of circles and the relationships to be found within...
