Kid2Kid: Determining the Meaning of Slope and Intercepts
Kid2Kid videos on determining the meaning of slope and intercepts in English and Spanish
Using Logical Reasoning to Prove Conjectures about Circles
Given conjectures about circles, the student will use deductive reasoning and counterexamples to prove or disprove the conjectures.
Generalizing Geometric Properties of Ratios in Similar Figures
Students will investigate patterns to make conjectures about geometric relationships and apply the definition of similarity, in terms of a dilation, to identify similar figures and their proportional sides and congruent corresponding angles.
Determining Area: Sectors of Circles
Students will use proportional reasoning to develop formulas to determine the area of sectors of circles. Students will then solve problems involving the area of sectors of circles.
Interactive Math Glossary
Making Conjectures About Circles and Segments
Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties and relationships among the resulting segments.
Determining Area: Regular Polygons and Circles
The student will apply the formula for the area of regular polygons to solve problems.
Making Conjectures About Circles and Angles
Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties of and relationships among the resulting angles.
Domain and Range: Numerical Representations
Given a function in the form of a table, mapping diagram, and/or set of ordered pairs, the student will identify the domain and range using set notation, interval notation, or a verbal description as appropriate.
Solving Problems With Similar Figures
Given problem situations involving similar figures, the student will use ratios to solve the problems.
Transformations of Square Root and Rational Functions
Given a square root function or a rational function, the student will determine the effect on the graph when f(x) is replaced by af(x), f(x) + d, f(bx), and f(x - c) for specific positive and negative values.
Transformations of Exponential and Logarithmic Functions
Given an exponential or logarithmic function, the student will describe the effects of parameter changes.
Solving Square Root Equations Using Tables and Graphs
Given a square root equation, the student will solve the equation using tables or graphs - connecting the two methods of solution.
Functions and their Inverses
Given a functional relationship in a variety of representations (table, graph, mapping diagram, equation, or verbal form), the student will determine the inverse of the function.
Rational Functions: Predicting the Effects of Parameter Changes
Given parameter changes for rational functions, students will be able to predict the resulting changes on important attributes of the function, including domain and range and asymptotic behavior.
Using the Present Progressive Tense | No Nonsense Grammar
Present progressives describe an action in progress, or something that started in the past and is still happening. It is formed with the helping "to be" verb in the present tense and the present participle of the verb.
Simple and Compound Sentences | No Nonsense Grammar
A sentence is a group of words that expresses a complete thought. A simple sentence contains a subject and a verb and by itself contains a complete thought. A compound sentence contains two independent clauses joined by a coordinator: for, and, nor, but, or, yet, so.
Using Proper Punctuation for Titles | No Nonsense Grammar
Small works (short stories, essays, magazine and newspaper articles, etc.) are indicated with the use of quotation marks. Larger works, such as books or movies, are indicated either through italics (in typing) or underlining (handwriting).
How to Recognize a Phrase | No Nonsense Grammar
A phrase is a group of related words that does not include both a subject and a verb. It only has one or the other!
Edison: Boyhood and Teen Years
Find out how young Thomas Edison’s curiosity got him into trouble, and how, during his teen years, he lost his hearing but gained confidence as an aspiring inventor, in this video adapted from AMERICAN EXPERIENCE: Edison.
