Statistically, waste may become a problem in the future if people do not take action. Using their knowledge of statistics and data representation, pupils take a look at the idea of waste generation. The four-part unit has class members...

Students access information at remote sites using telecommunications, identify impacts by reviewing past El Ni??o events, make and use scale drawings, maps, and maps symbols to find locations and describe relationships.

Students explore the concept of interdependence. In this integrated interdependence lesson, students interpret graphs and charts that require them to analyze the relationship between Mexico and the United States. Students also...

Young geologists explore volcanoes with a series of engaging geology activities. First, they learn the difference between magma and lava before coloring and labeling the parts of a volcano. During the lab, individuals watch a...

Young geologists begin exploring volcanoes of different structures and states: active, extinct, or dormant. During the lab, they make three models and compare different types of volcanoes, including composite, cinder cone, and...

Explains how simple polygons translate into matrices and how to use 2x2 matrices to represent transformations in a plane. Includes video demonstrating an example where a vector must be rotated 90 degrees using matrices. [4:18]

An exponential function is a nonlinear function that has the form of y=a*b^x, where a != 0, b > 0. An exponential function with a > 0 and b > 1, like the one above, represents an exponential growth and the graph of an...

A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the...

The absolute value of a number a is written as |a| and represents the distance between a and 0 on a number line. An absolute value equation is an equation that contains an absolute value expression. The equation |x|= a has two solutions...

This resource is about factorizing trinomials of the form x^2+bx+c by making them into a product of two binomials x^2+bx+c=(x+m)(x+n) where m+n=b and m*n=c

You can factor polynomials of the form ax^2 + bx + c. If a is positive, then ax^2+bx+c=(x+m)(ax+n) where c = m*n, a*c = p*q and b = p+q = a*m + n

A nonlinear function that can be written on the standard form ax^2 + bx + c,where a is not = 0, is called a quadratic function. All quadratic functions hava a U-shaped graph called a parabola.

A quadratic equation is an equation that can be written on the standard form ax^2 + bx + c = 0, where a is not = 0. One way of solving a quadratic equation is by factoring. Another way of solving a quadratic equation is to solve it...

All equations are composed of polynomials. If you know how to solve equations containing polynomials of the first degree, then you can solve equations of higher degree. One way to solve a polynomial equation is to use the zero-product...

If you've got a quadratic equation on the form of ax^2 + c = 0 Then you can solve the equation by using the square root of x = square_root(-c/a) or x = -square_root(-c/a)

An algebraic expression where both the numerator and the denominator are polynomials e.g.(x+3) / x is called a rational expression. Since the denominator can't be zero there are values of x which are excluded from the rational...

An equation that contains at least one rational expression is called a rational equation. You solve a rational equation as you solve any other equation.

Demonstrates how to calculate the area of two-dimensional shapes using formulas. Covers parallelogram, triangle, trapezoid, and circle. Includes a video modeling how to find the area of a circle and a triangle. [0:59]

Explains what the slope-intercept form is and how to find the equation of a line given two points on it. Includes modeled video lesson. [3:32]

Learn how to solve problems that involve finding unknown supplementary, complementary, vertical, and adjacent angles in this Math Shorts video from the Utah Education Network and Planet Nutshell, Inc.

In this unit, students learn the very basics of navigation, including the different kinds of navigation and their purpose. The concepts of relative and absolute location, latitude, longitude and cardinal directions are discussed, as well...
