Watch out for Parentheses
It is important for the algebra learner to understand the use of parentheses. Mathematicians of all levels can make errors with nested parentheses. This will give them some practice. It makes for a good class starter or quick assessment.
Curated OER
QwikQure Algebra
Fourth graders are introduced to the problem using a bottle of medicine. They estimate the volume of the medicine and predict the instructions on the bottle. They then think about how they might solve the problem before asking them to...
Curated OER
Boolean Algebra
Students play a series of games involving Boolean logic. In this Boolean Algebra lesson plan, students participate in games such as "George Boole Says" to explore Boolean logic. The format of the lesson plan is difficult to...
Curated OER
The Fishing Pole Problem
In this algebra worksheet, 11th graders use algebra to solve a word problem related to fishing. They figure out how to get a boy home form his fishing trip as their are restrictions as to what he can take on the bus. There is an answer key.
Curated OER
Shortest Distance Problem
In this algebra worksheet, students solve 1 shortest distance problem. This is a challenging problem that requires students to apply knowledge and use their critical thinking skills. A fully explained solution is included.
Curated OER
Concepts, Patterns, Formulas, Substitution
In this algebra lesson, young scholars define algebraic terms and rewrite them using math symbols. There are 10 problems drawing correlations to geometry as well as algebra.

Margin of Error When Estimating a Population Mean (part 1)
We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.
EngageNY
Distributions—Center, Shape, and Spread
Data starts to tell a story when it takes shape. Learners describe skewed and symmetric data. They then use the graphs to estimate mean and standard deviation.
EngageNY
Interpreting the Standard Deviation
Does standard deviation work for non-symmetrical distributions, and what does it mean? Through the use of examples, high schoolers determine the standard deviation of a variety of distributions and interpret its...
EngageNY
Dividing by (x – a) and (x + a)
Patterns in math emerge from seemingly random places. Learners explore the patterns for factoring the sum and differences of perfect roots. Analyzing these patterns helps young mathematicians develop the polynomial identities.
EngageNY
Using a Curve to Model a Data Distribution
Show scholars the importance of recognizing a normal curve within a set of data. Learners analyze normal curves and calculate mean and standard deviation.
