Basic Geometric Definitions: Lesson

Challenge your geometry class with this connect-the-dots activity! Scholars use a ruler to complete simple shapes through connecting dots in 6 shape-identification problems, and identify it from 4 choices: triangle, square, rectangle, or...

The coordinate plane links key geometry and algebra concepts in this approachable but rigorous unit. The class starts by developing the distance formula from the Pythagorean Theorem, then moves to applications of slope. Activities...

Geometry is full of shapes, figures, and corresponding things here and there. The guide shares all of the key pieces of geometric information in a nicely color-coded and labeled sheet. 

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Transformations are more than the process in which sports cars become fighting robots. Listed in terms of which transformations give congruent or similar figures, several resources provide definitions and examples of the four...

Introduce your fifth graders to the coordinate plane, ordered pairs, and plotting points on any of the four quadrants. This wonderful resource makes preparation for your math class quick and easy. It explains everything the class will...

Progress through levels of dividing a polynomial by a monomial. Four examples show scholars the procedure to divide a polynomial by a monomial. The first example uses a binomial divided by a monomial, and each of the others progress...

If the slope and y-intercept aren't known, just find them. Scholars watch a short video that covers an example of writing an equation of a line in slope-intercept form given a table of values. They learn to apply the slope formula to...

It's not in the bag. An interactive provides the probability of picking a certain color marble from a bag after several marbles have been removed. Young mathematicians learn about dependent events from this resource.

A good definition of a mathematical vocabulary term is worth its weight in gold. This video tutorial defines the term ratio, provides three different ways ratios are expressed, and gives a real-life ratio example. Good video for those...
