The djinni in this resource offers gold coins. Learners use the properties of exponents to make their decision as one offer increases exponentially. This makes a great group project. As the commentary suggests, start by having groups...

The key to understanding is making connections. Scholars explore angle dilations using properties of parallel lines. At completion, pupils prove that angles of a dilation preserve their original measure. 

Build boxes using unit cubes to compare surface area and volume. The group performs multiple experiments to determine properties of volume, such as if it makes a difference which order the dimensions are multiplied in. Extensive...

Young scholars investigate the concept of building materials and how they are used to create different things. They focus upon the availability, cost, flexibility, and strength of different building materials. This is done by taking part...

Young scientists investigate types of rocks in this instructional activity. They collaborate to examine groups of rocks, make written descriptions of them, and use websites to help them identify the types of rocks they are.

Ninth graders investigate systems of linear equations.  In this Algebra I lesson, 9th graders determine which method is the best for solving a systems:  graphing, substitution, or elimination.  Students choose...

Students solve problems using the distributive property. In this algebra activity, students solve equations by multiplication and combining like terms. They graph their lines on the calculator.

Second graders explore the properties of primary color and investigate what happens when primary colors are mixed. They listen to the story The Crayon Box That Talked and list the colors. They experiment mixing primary colors and...

Students practice solving problems with non-right triangles. In this precalculus lesson, students define and identify the properties of the Law of Cosine. They solve problems and investigate the history behind Cosine.

Middle schoolers relate the division of monomials to multiplication. In this division of monomials lesson, students divide monomials by factoring and dividing common factors from the originals. They check their answers by multiplication....

Young mathematicians solve arithmetic and simple algebraic equations using properties of real numbers, equality, and inequality. Justifying the procedures is their next task. They solve a problem involving linear inequality and justify...

Middle schoolers add, subtract, multiply, and divide rational numbers. They find the square and the cube of numbers. They create a game incorporating computation on rational numbers. Everyone works together to write and evaluate...

Geometry is everywhere, and I mean everywhere! Those skillful mathematicians discuss shapes and then come up with a well-researched list of shapes seen in everyday applications. They put their knowledge of shapes to work as each small...

Students investigate the properties behind the quadratic equation. In this algebra lesson, students identify quadratic equation in the real world. They graph the parabola and identify the vertex and intercepts.

Learners explore multiplying fractions and their relationship to parts of a whole. They draw and shade fractional parts to show parts of a whole and fractional parts of a fraction. Pupils also use an Internet site for interactive...

Explore physical science by participating in a visual spectrum experiments. Budding scientists identify the colors in the color spectrum and view the colors in class by utilizing cellophane, flash lights, and other arts and crafts...

Students apply definitions and theorems to verify special quadrilaterals using coordinate geometry. They apply the slope formula, the midpoint formula, and the distance formula to justify that a given quadrilateral is a parallelogram....

Teach the connection between area models and the distributive property through problem-solving. The 22nd activity in a series of 29 explains the distributive property graphically. Learners build area models from word problems and convert...

These aren't models made of clay. Young mathematicians model given population data using exponential functions. They consider different models and choose the best one.

Sharpen your pencil and grab a ruler, it's time to draw some quadrilaterals! Given the definition of a parallelogram, rectangle, and rhombus, learners draw examples and nonexamples of each figure. The three definitions are...

There is more than one way to solve a multiplication problem, and many learners find that the lattice multiplication method can be a helpful one. Fourth graders take an initial formative assessment before working in groups of two or...
