Curated OER
Odd Thing Out
Pupils listen to the math problem provided and work in groups to solve. They think about the objects and write down their information in a table. Class construct the table on a large piece of paper that can be put on the wall after the...
Curated OER
Rabbits
Learners 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
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...
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
Spheres
Students work algebraic expressions with various types of powers to find the solutions. They Students also become familiar with problems that involve the square roots of numbers. The work should be completed with computational accuracy.
Curated OER
Adding Ten Tiles I
Pupils 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
Space Crossing
Students critically follow a chain of reasoning to devise a decent problem solving technique to be applied to a reasonable problem. They also examine how to use logical arguments.
Curated OER
Rings and Diamonds
Fifth graders solve a problem by using systematic problem solving strategies. They determine if there is enough information to solve the problem. They solve a problem involving geometric shapes and area.
Curated OER
My Son is Naughty
Students find factors of numbers; work systematically; and use logic to explain away certain possible number combinations. They then devise and use problem solving strategies to explore situations mathematically.
Curated OER
What is s and t?
Students formulate and solve various types of equations. They become familiar with different types of patterns and apply the knowledge to solving mathematical problems from analyzing them.
Curated OER
The Lady's Age
Students use a game to establish the context of solving problems in a systematic and mathematical fashion. They also solve various types of equations to find reasonable solutions.
Curated OER
Occupations - Matching Exercise
Students participate in a discussion about occupations and what type of transportation they use, the equipment they use, or the building they have. They then complete the worksheet provided.
Curated OER
Using Tens Frames for the Strategy of Bridging to Ten
Second graders are given a problem. They are shown a fixed frame of 9 and students are asked to say where the six more should go without touching the tens frame. Students are invited to answer the question and show go they got the answer.
Curated OER
Average Looking
Students use measurements of their classmates to find the average (means and modes) of their facial features. They use their findings to create a three-dimensional "class head." Examples and assessment materials are included.
