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
Buttons and Bears
Students read the problem and then identify the important information in the problem and highlight. They then brainstorm for ways to solve the problem by drawing a picture and working in pairs.
Curated OER
Fifty Toes
Students guess the subject of the given problem by reasoning. Then they discuss the ways that the problem could be solved by keeping track of their counting in 10s and showing their work.
Curated OER
Cannon Balls
Second graders investigate 2 and 3 dimensional objects. They discuss the characteristics of the triangle. Students create sequential patterns and describe the rule for their pattern.
Curated OER
PSTV
Students figure the amount of programs can fit into a certain time frame. The use of problem solving allows for the student to examine how things can occupy time. They measure the time frame for one program then use that amount to...
Curated OER
Rabbits
Students review what they think doubling means and double numbers mentally, for example, 5, 12, 16. They share their solutions and discuss how they doubled. They work together on a problem that is beyond mental working and solve...
Curated OER
Toothpick squares
Students state the general rule for a practical situation. They describe a continuing pattern. They use toothpicks to help visualize the problem and answer it correctly.
Curated OER
At The Movies
Pupils work systematically to find all the possible combinations. They Students write and solve problems which involve whole numbers and which require a choice of one or more of the four arithmetic operations.
Curated OER
Legs in the Barn
Students listen to the problem being read. They then brainstorm possible approaches and are encouraged to plan ways of recording their work so that others examine what they have done and share their findings.
Curated OER
The Rock Pool
Third graders use number sense and appropriate problem solving techniques to solve the assigned problems. They write out the solutions to the assigned problems. They work in groups to solve the problem before reporting back to the whole...

Paul's Patterns
Fourth graders listen to the problem. As the students work ask them questions that require them to describe the patterns in their own words.
If the students are having problems with finding the patterns encourage them to explore the...

The Farmer's Sheep II
Fourth graders listen to the story of a farmer who only likes to be able to see nine sheet from his window. His wife has brought him another sheep - what now? They work together in pairs to solve the problem and share solutions.
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
The Clumsy Tiler S
Fourth graders solve a series of parallel problems. They use statistics, geometrical, and numerical aspects to solve the problem. Students create a pattern that answers the problem.
Curated OER
Can Stack
Young scholars are able to find the rule for summing consecutive numbers;
identify the pattern of triangular numbers. They then solve the given problem using logic and mathematical reasoning.
Curated OER
Base 3
High schoolers investigate this problem that aims to give a better idea of our decimal system by looking at a comparable system - the base 3 system. By seeing how base 3 numbers work students should have a better appreciation of base 10...
