What makes number pairs perfect? The resource provides five problems regarding perfect pairs of numbers, the definition of which changes in complexity with each task. Solutions require pupils to apply number sense and operations, as well...

Positive or negative, zero or no solution, are all possibilities for the solution of a linear equation. Here the resource gives examples of linear equations in one variable and their type of solutions. The resource comes with commentary...

This instructional activity is all about systems of equations and their graphs. Algebra learners create and solve systems of equation using tables and graphing. They identify the point of intersection of a system of equation, and...

Liken a cell and its organelles to a tiny person and its organs. After gathering information on cell structures and their functions, small groups collaborate to come up with an analogy of their own. They produce a collage describing the...

Long considered the symbol of safe harbor and steadfast waiting, the lighthouse gets a mathematical treatment. The straightforward question of distance to the horizon is carefully presented, followed by a look into the...

Students read passages from several sources and evaluate the text for various criteria. In this problem solving lesson plan, students evaluate character problem solving processes after reading passages. They will use a Venn Diagram to...

Investigate the world of unknown quantities with a creative set of five lessons that provides problem situations for varying grade levels. Each problem presents a scenario of fruit with different weights and a balance scale. Using the...

Explore distance and time factors to build an understanding of rates. A comprehensive set of problems target learners of all grade levels. The initial problem provides distance and time values and asks for the winner of a race. Another...

Elementary learners identify the main elements of story structure and form questions to summarize their reading. They listen as the teacher reads a story and then write questions to determine (1) main characters, (2) setting, (3)...

Engineering design projects serve as great opportunities for collaborative problem solving. In this case, students work in small groups designing, building, and eventually testing a structure that meets a teacher-specified objective. It...

Develop an understanding of algebraic sequences through an exploration of patterns. Five leveled problems target grade levels from elementary through high school. Each problem asks young mathematicians to recognize a geometric pattern....

What's the least number of colors needed to color a U.S. map? The lesson begins by having pupils view a video clip on continuous and discrete phenomenon, then launches into an activity reminiscent of Zeno's paradox. A separate video...

Creative activities help bring literature alive. The first of a set of lessons designed to accompany selections from Theme 4: Problem Solvers uses activities such as skits, responses to music, and social studies projects. These...

Mathematicians use an inquiry method to solve linear equations. In this linear equations lesson, students practice solving equations using addition, subtraction, multiplication and division. They solve multi-step equations and equations...

In "Nuclear Arthmetic," first-time physical scientists examine atomic structure and the periodic table of elements. The are given the formula, "N = A-Z," in which N is the number of neutrons, A is the atomic mass, and Z is the atomic...

Shake your earthquake-resistant building prototype! Groups create structures using coffee stirrers and clay that can withstand seismic waves. They then test their structures against their own earthquakes.

If pupils think the three types of rock are classic, punk, and hard, these puzzles offer gentle correction. Scholars match the type of rock to how it formed and an example in four grid puzzles. Each requires problem-solving and...

Students select what kind of sculpture they would most like to create. They construct a model, place it in a central location and receive a number. Then they vote on the sculpture they would like to construct as a group project.

Students determine patterns. In this mathematics lesson, students act out a skit, play a sequence game, and complete patterns. Students use problems solving skills.

Having problems with proportions? Then solve these proportion problems with an exercise that asks learners to first individually solve a set of problems involving ratios and proportional reasoning. Groups then discuss provided...

Solving problems about pen and paper with systems of equations ... or is it the other way around? In the lesson, learners first interpret expressions and use equations in two variables to solve problems about notebooks and pens. They...

Teach your class to think outside the box. Scholars use the concept of equality to solve a problem in the assessment task. They determine how to use a scale to identify the one box out of a set of nine boxes that is heavier than the others.

After completing a task involving examining the ratio of areas of triangles and circles in a given figure, scholars examine sample responses to identify other strategies they could use to solve the problem.

Stop, Think, Act, Review! Scholars use the STAR method to role play two conflict resolution scenarios about childhood problems such as jealousy or cheating. Then, the larger group judges each case to determine if the compromise is a...
