Properties of Logarithms
In this algebra worksheet, 11th graders solve logarithmic problems using the properties of logs. They condense and expand logs using the correct properties. There are 78 problems with an answer key.
Illustrative Mathematics
Distance across the channel
Here you will find a model of a linear relationship between two quantities, the water depth of a channel and the distance across the channel at water level. The cross section of the channel is the shape of an isosceles trapezoid. The...

Exploring Power Functions 1
Learners describe the end behavior of polynomial functions. Pupils relate the behavior of the graph to the exponent of the graph. They differentiate graphs with odd-exponent and graphs with even exponents.
Curated OER
Transformations of Functions 1
Learn how to solve problems with transformation. Students perform transformation on their graphs. Then, they use the TI to create a visual of the graph as it is moving along the graph.
Curated OER
Boolean Algebra
Students play a series of games involving Boolean logic. In this Boolean Algebra lesson, students participate in games such as "George Boole Says" to explore Boolean logic. The format of the lesson is difficult to read.
Curated OER
Concepts, Patterns, Formulas, Substitution
In this algebra lesson, learners define algebraic terms and rewrite them using math symbols. There are 10 problems drawing correlations to geometry as well as algebra.

A Focus on Square Roots
Pupils learn to solve square root equations and rationalize denominators. Problems include those with extraneous solutions.
EngageNY
Awkward! Who Chose the Number 360, Anyway?
Don't give your classes the third degree. Use radians instead! While working with degrees, learners find that they are not efficient and explore radians as an alternative. They convert between the two measures and use radians with the...

Calculating Probabilities of Events Using Two-Way Tables
Tables are useful for more than just eating. Learners use tables to organize data and calculate probabilities and conditional probabilities.
EngageNY
Types of Statistical Studies
All data is not created equal. Scholars examine the different types of studies and learn about the importance of randomization. They explore the meaning of causation and when it can be applied to data.
