Rotation ppt description This PowerPoint is eight slides long and introduces one of transformation (rotation) to intermediate students. Slide #3 introduces the rules for rotation about origin in the counter-clockwise direction at three angles (90°, 180°, and 270°). In order to achieve a clockwise direction just reverse the rules for 90°, and 270°; the rule for 180° remains the same. I give a reference sheet that has the rules. Slide #4 illustrates the 270° and 90° are the same rotation. Some

Reflection ppt description This PowerPoint is eight slides long and introduces one of transformation (reflection) to intermediate students. Slide #3 stresses the change in orientation. Slide #4 shows that figure and its reflection are equally spaced from the line of reflection. Slides #5 and 6 illustrates how to find the line of reflection by dividing the range between reflecting points by two. Many students do this but they don’t know how to explain it. The exit question slide reviews thre

This PowerPoint is 10 slides long. This lesson satisfies the some of the requirements for common core (HSN.RN.A.2). Slide #2 and 3 are the vocabulary slides, be sure to look at the PowerPoint notes because it contains the concepts that are to be stress with each slide. Slide #4 illustrates how to the radical symbol of the radical is a grouping symbol. It is a nice comparison of an expression that is grouped differently. Slide #5 is a review of squares; students should know 1-20 and 25 square

Pythagorean ppt description This PowerPoint is eleven slides long and expounds the Pythagorean Theorem to intermediate students. Slide #3 describes the differences between the dimension and area of a leg of a right triangle. Slide #4 is an old proof that has been used many times; this slide has a great animation. Slides #5-7 illustrates how to find a length of a tilted square. (Common Core: 8.G.7 Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world

This PowerPoint illustrates three different dilation problems with different variations. It satisfies the some requirements for common core 8.G.3. The first problem has two similar figures that share origin as an ordered pair. The second problem is to decrease by a factor of three. The third problem is harder because the center of dilation is not origin. The slide ends with same triangle repositioned with the center of dilation at origin. Many times dilation is taught by just increasin

This Jeopardy PowerPoint is good for review or parent night to have students demonstrate their math skills. The categories are “Name that Property”, “Substitute Evaluate & PEMDAS”, “and Adding like Terms”, “ Multiplying Exponents and Dividing Exponents”. This lesson reviews many of the requirements for common core. I normally will have two teams and rotate the person who it answering the questions. If they correctly answer a question they switch with a team mate. If you use this for a paren

Pyramids and Surface Area ppt description Explore how to find surface area of regular and irregular pyramids with real world pyramids. This lesson satisfies the some of the requirements for common core 7.G.6 and 8.G.7. It is well suited for the intermediate (middle) school students. A prerequisite for this lesson is that students know how to use Pythagorean Theorem. Slide #2 is the vocabulary slide, be sure to look at the PowerPoint notes because it contains the concepts that is to be stress

Function Table ppt description This PowerPoint is ten slides long and builds on previous knowledge of a simple function. This lesson satisfies the requirement for common core 8.F.1 and several other standards. It is well suited for the intermediate (middle) school students. Slide #2 is the vocabulary slide and the animation identifies the input and output coordinates. Slide #3 illustrates how the input, function and output are used to create an ordered pair. The animations are slow to begin

Translation ppt description This PowerPoint is eight slides long and introduces one of transformation (translation) to intermediate students. Slide #4 stresses the horizontal and vertical movement of each point. Slide #5 and 6 introduces the correct labeling “prime and double prime”. The exit question slide reviews three concepts that I wanted to stress; vocabulary, horizontal & vertical movement, and labeling. This is short and sweet but if students understand this, they should have success

This PowerPoint has two real world problems Instagram posts and cell phone plans, vocabulary, exit questions, templates for notes; it satisfies the requirement for common core 8.EE.8 and several other standards. The first problem model is a one-step equation the second problem is comparison of two cell phone plans. The vocabulary slide defines independent and dependent variables. Review the notes for each slide because they describe key concepts for the students. The white note taking icon i

Building Equations ppt description This PowerPoint is nine slides long and builds on previous knowledge of a slope intercept form. This lesson satisfies the some of the requirements for common core 8.EE.6. It is well suited for the intermediate (middle) school students. Slide #2 is the vocabulary slide, be sure to look at the PowerPoint notes because it contains the concepts that is to be stress with each slide. Slide #3 illustrates how to find the rate of change in rise (y) and run (x) from

Box Review ppt description This PowerPoint is 15 slides long. This lesson satisfies the requirements for common core 7.G.6. It is well suited for the intermediate (middle) school students. Students must know how to round numbers, measure dimensions, and substitute and solve volume/surface area formulas. Slide #2 and 3 are the vocabulary slides. Slides #4 through 9 model how to find the volume and surface area of a Crystal Light box. Pause at slide #10 for the students to complete the guided

Irregular polygons can be difficult for students. This is a way to simplify finding area by inscribing the geometric shape and removing what does not belong. This lesson meets the requirements for common core 6.G.1. You will find area of special quadrilaterals and polygons by composing into rectangles or decomposing into triangles and other shapes in the context of mathematical problems. Slide #2 is a vocabulary slide. In slides #3-5, you model finding the area of three different irregular

Singapore Math a ppt description Singapore is not the easiest method to teach but it allows students to visualize their math. The purpose of Singapore Math is to teach kids how to think. It deals with part to whole relationships. Slides #3 and 4 are fraction problems. The first problem deals with a denominator of 5 and the second has a denominator of 10. The part to whole relationship is key. This PowerPoint will not teach Singapore math it only provides examples. Note: My philosophy for

Singapore Math ppt description Singapore is not the easiest method to teach but it allows students to visualize their math. The purpose of Singapore Math is to teach kids how the think. It deals with part to whole relationships. Slides #3 and 4 are two different problems. One is a ratio problem the other is a height problem. This PowerPoint will not teach Singapore math it only provides examples. Note: My philosophy for slide shows. Long slide shows become very boring very quick. I use

Pyramids and Volume ppt description Explore how to find volume of real world pyramids. This lesson satisfies the some of the requirements for common core G.GMD.3. It is well suited for the intermediate (middle) school students. A prerequisite for this lesson is that students know how to use Pythagorean Theorem. Slide #2 is the vocabulary slide, be sure to look at the PowerPoint notes because it contains the concepts that are to be stress with each slide. Slides #3-4, shows how to draw a pyr

Multiplying Integers Rules ppt description A math teacher shared this with me at a math competition a couple of years. It uses a tic-tac-toe board to teach integers rules for multiplying and dividing I decided to make a slide show with it. Students will often put a tic-tac-toe board on their quizzes.

This is just a table of squares from 1 to 20. It is a nice reference sheet for students.
