Polynomial, Rational, and Radical Relationships
This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...
Mathematics Vision Project
Module 6: Congruence, Construction, and Proof
Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This unit...
Illustrative Mathematics
Lake Algae
Introduce learners to exponential growth with this real-world problem about algae that is rapidly spreading across a lake in a city park. The task presents the rate of growth and an end value and asks learners to determine what happened...
Curated OER
Between The Extremes
Students analyze graphs for specific properties. In this algebra lesson, students solve equations and graph using the TI calculator. They find the different changes that occur in each graph,including maximum and minimum.
Curated OER
Investing
Learners collect data on investments and draw conclusions. In this algebra lesson, students analyze exponential graphs as they relate to money. They discuss the cause of an account balance being high or low.
Curated OER
Conductivity of salt Solutions
Students investigate the concentration level of solutions. In this math/science lesson, students identify three different ionic compounds. They predict the conductivity of each using their collected data.
Curated OER
Slip Slide'n Away
Students analyze the sliding of boxes along a warehouse floor. In this algebra lesson, students connect math and physics by calculating the friction created by the sliding of each box. They develop faster method to move the box, based on...
Curated OER
Using Systems of Equations
In this algebra instructional activity, students solve systems of equations. They use substitution, elimination and graphing to solve. There are 33 questions with an answer key.
Curated OER
Systems of Equations
In this Algebra 2 learning exercise, students solve systems of equations and inequalities then graph the solutions on a number line. There are 11 problems to solve.
Curated OER
Guess the Age
Students rewrite word problems using symbols. In this algebra lesson, students rewrite equations graphically, algebraically and verbally. They relate the concepts to the real world.
Curated OER
Conjectures and Conclusions
Learners draw conclusions and make conjectures given a specific scenario. In this geometry lesson plan, students model real life scenarios using properties of triangles. They model number facts and explain why the outcome is what it is.
Curated OER
Numerical Analysis: Polynomial Interpolation
In this polynomial worksheet, students identify the interpolated and extrapolated value of given equations. This four-page worksheet contains approximately ten problems. Explanations and examples are provided.
Curated OER
Inverse Variation
In this algebra learning exercise, learners find the inverse of an equations. They graph their solutions and analyze it. There are 8 questions.
Curated OER
La Toteca- A Tropical Paradise
Students collect data on the time of the ferry. For this algebra lesson, students use the data to predict a ferry schedule. They also compute the depth where oxygen would be needed when diving.
Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry instructional activity, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
