Dilations in math. How to perform a dilation -Formula and Interactive Demo and Practice Problems Answer: A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of each type of dilation (one that gets larger and one that gest smaller) Example 1 The picture below shows a dilation with a scale factor of 2. Grid Paper PDFs - Nightly Free Online Graph Paper / Grid Paper PDFs Downloadable and very printable, I find these PDFs extremely useful. Tip number one!

Parabolas Parabolas(This section created by Jack Sarfaty) Objectives: Lesson 1: Find the standard form of a quadratic function, and then find the vertex, line of symmetry, and maximum or minimum value for the defined quadratic function. Lesson 2: Find the vertex, focus, and directrix, and draw a graph of a parabola, given its equation. Lesson 3: Find the equation of our parabola when we are given the coordinates of its focus and vertex.
Interactive GeoGebra Student Worksheet on Triangle Centers Geometry teachers! This is for you! Explore this wonderfully color-coded interactive diagram with your students. It includes lots of juicy questions at the bottom to help your students investigate the ins and outs of triangle centers and what they are used for in practical situations. The only thing it assumes is that you’ve explained the definitions of medians, altitudes, perpendicular bisectors, and angle bisectors. Common Core Standards : CCSS.Math.Content.8.G.A.3 3. Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates. Transformations are fascinating things in real life, in movies, and of course, in geometry. But if your students expect shapes to turn into giant fighting robots, they've got another thing coming.

Sample Problems from Chapter 1 Chapter 1: 7 year olds do It should be noted here that Morris Klein in his book "Mathematics, The Loss of Certainty" describes the confusions of and the mistakes made by, the great mathematicians like Newton, Leibnitz, Euler and the Bernoullis with infinite series and infinite sequences. So I figure if we start young people working on this material, they will make lots of mistakes, but will have a good chance of understanding it later on in high school and college.We're doing important mathematics here, and at the same time we're involving young people in a lot of arithmetic!
