Learn through constructions! Learners examine a translation using constructions and define the translation using a vector. Pupils then construct parallel lines to determine the location of a translated image and use the vector as a guide.

Prove theorems through an analysis. Learners find the midpoint of each side of a triangle, draw the medians, and find the centroid. They then examine the location of the centroid on each median discovering there is a 1:2 relationship....

Inscribed angles are central to the instructional activity. Young mathematicians build upon concepts learned in the previous instructional activity and formalize the Inscribed Angle Theorem relating inscribed and central angles. The...

In the first installment of a 21-part module, scholars build on previous understandings of probability to develop the multiplication rule for independent and dependent events. They use the rule to solve contextual problems.

Fractions, ratios, and proportions: what do they have to do with segments? Scholars discover the midpoint formula through coordinate geometry. Next, they expand on the formula to apply it to dividing the segment into different...

Solving systems by substitution can be a challenging topic in algebra I. Here is a lesson that builds on students' understanding of intercepts to begin the process of substitution, and all work is reinforced graphically to build...

Use the resource to teach methods for solving exponential equations. Scholars solve exponential equations using logarithms in the twenty-fifth installment of a 35-part module. Equations of the form ab^(ct) = d and f(x) = g(x) are...

In this math worksheet, young scholars solve the problems that are correlated with the objectives. Each practice set has an in depth example.

In this y-intercept worksheet, students graph functions and determine the y-intercept of the equation. Explanations and examples are provided prior to the exercises. This two-page worksheet contains ten problems.

There are many equations Algebra I students are not ready to solve. Graphing to solve gives them a strategy to use when they are unsure of an algebraic approach to solve the problem. The lesson exposes learners to a wide variety of...

What was the property again? Tired of hearing this from your pupils? Use this table to organize properties studied and as a reference tool for individuals. Learners apply each property in the third column of the table to ensure their...

Apply, apply, apply! A measurement activity applies a number of concepts to help learn a new construction. Scholars learn to divide a segment into n equal parts using a method that uses the Side Splitter Theorem and a method...

Prove that an equation in slope-intercept form names only one line. At the beginning, the teacher leads the class through a proof that there is only one line passing through a given point with a given slope using contradiction. The 19th...

Students explore the concept of quadratic equations.  In this quadratic equations instructional activity, students determine what shifts of a parent graph will look like by describing in sentences.  Students factor quadratic...

In this college level Pre-Calculus worksheet, students use polynomial and rational functions to solve application word problems.  The three page worksheet contains forty-four problems.  Answers are not included. 

Students explore a linear, a parabolic, and a log function.  For this Algebra II/Pre-calculus lesson students investigate the graph a line, a parabola, and a log function.  Students examine the three graphs as they compare and...

In this United States population worksheet, students solve word problems about the United States population by using the quadratic formula. Students complete 6 problems.

Learners examine parallax and angular measurements.  In this investigative lesson students calculate distances of objects and map their results.

Students solve word problems which involve graphing systems of equations. After discussing methods of solving word problems, the teacher demonstrates how to solve problems which involve graphing. They work together, at their desks, and...

In this math worksheet, students collaborate with a "study buddy" or "coach" to learn whether an angle is acute, obtuse or right. Students follow the directions to go through the process of deciding what classification an angle has....

This site gives a description of intersection of sets along with an example. There are links to related terms, challenging problems, more information, and the interactive check point involving set intersections located in the left-hand...
