Linear and Quadratic Functions
In this algebra worksheet, 11th graders solve quadratic functions using the quadratic formula. They take the square roots of both side of each equation then graph both the linear and quadratic functions. There are a total of 84 problems...
Curated OER
Which Quadrilateral Is It?
Students prove conjectures about geometric figures on the plane or in space using coordinate geometry. They develop fluency in operations with real numbers, vectors and matrices using mental computation or paper-and-pencil calculations...
Curated OER
Exploring Geometric Figures
Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain an...
Curated OER
Exploring Linear Equations
Third graders use graphing calculators to graph equations. They make visual models of algebraic expressions and they can readily see that an equation represents something.
Curated OER
Graphing System of Equations
Students solve system of equation. In this algebra lesson, students graph, substitute and eliminate to solve system of equation. They identify the point of intersection and how many solution each system will have.
Curated OER
Constructing Midsegments of Triangles
Students construct midsegments. In this geometry lesson, students make conjectures and apply properties of triangles to solve problems. They complete an activity on the computer.
Curated OER
How Has Math Evolved?
Eighth graders pick a topic or person to research related to the history of mathematics. They brainstorm and create a concept map, using the multimedia software inspiration, about what they are researching and want to examine. They then...
Curated OER
Finding the Measure of Segments
High schoolers observe and solve examples of betweenness, ruler postulate, and segment addition postulate. They complete the Finding the Measure of Segments worksheet using the distance formula.
Curated OER
A Perpendicular Pilgrimage
Ninth graders design a safe passage through a 2-D obstacle. In this geometric math instructional activity, 9th graders engage in a hands on activity to better understand the concept of geometric and algebraic perpendicularity. Students...
Curated OER
Choosing a Summer Job
What did you do over your summer vacation. Young wage earners must compare summer job options, and determine when each job earn the same amount and what that amount be. This be done by creating, graphing, and solving systems of...
