This first of twelve algebra 2 resources provides a broad review of many algebra 1 concepts through a number of separable lessons and labs. Starting with the real number system and its subsystems, the sections quickly but thoroughly...

A basic set-up leads to a surprisingly complex analysis in this variation on the question of surrounding a central circle with a ring of touching circles. Useful for putting trigonometric functions in a physical context, as well as...

Engage conversation and explore the journey as you challenge young readers to interpret the german folktale, "The Fisherman and His Wife" written by literary brothers Jacob and Wilhelm Grimm.

Explore distance and time factors to build an understanding of rates. A comprehensive set of problems target learners of all grade levels. The initial problem provides distance and time values and asks for the winner of a race. Another...

Explore using units with scientific notation to communicate numbers effectively. Individuals choose appropriate units to express numbers in a real-life situation. In this 13th lesson plan of 15, participants convert numbers in scientific...

Let's get this block party started and learn about decimals! Here are four main lessons that teach the operations with decimals while using base 10 blocks to provide a hands-on learning approach. Supplemental worksheets and other...

Some data just doesn't follow a straight path. Learners use line graphs to represent data that changes over time. They use the graphs to analyze the data and make conclusions.

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.

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Round and round they go ... where they stop, only scholars will know. By writing systems of equations, classes determine the number of cars a roundabout can handle given specific constraints. Systems use up to six variables and become...

Young geometers develop one of the fundamental properties of quadrilaterals (connecting side midpoints gives a parallelogram) in this short but thought-provoking exercise. Using a combination of hands-on techniques and abstract algebraic...

Examine the relationship between time and geometry. A series of five lessons provides a grade-appropriate problem from elementary through high school. Each problem asks learners to compare the movement of the hands on a clock to an angle...

Stars seem to be a far away mystery... but it turns out we know much more about stars than one would think! An engaging lesson shows learners how to read a light spectrum to determine the temperature and chemical makeup of a star....

The world's largest measured earthquake happened in 1960 in Chile, reaching a terrifying 9.5 magnitude on the Richter Scale. The second lesson in the 20-part series introduces earthquakes and fault lines. Scholars map where previous...

How accurate is data collected from a sample? Learners answer this question using a simulation to model data collected from a sample population. They analyze the data to understand the variability in the results.

Challenge readers to read closer in an activity based on the Socratic questioning strategy. As kids read Antoine de Saint Éxupery's The Little Prince, they use sentence starters to ask deeper questions about the text, and...

You've heard that it is true, but can you prove it? Scholars learn the Pythagorean Theorem through proof. After an overview of proofs of the theorem, learners apply it to prove triangles are right and to problem solve. This is the second...

Show learners the power of mathematics as they model real-life designs. Pupils graph a periodic function by comparing the degree of rotation to the height of a ferris wheel. 

A second attack at figuring out the number of leaves on a tree, this activity makes both an excellent follow-up to version 1 and a stand-alone activity. Learners practice setting parameters and deciding acceptable estimate precision, and...

The second lesson of a pair about Paul Laurence Dunbar, this plan focuses in particular on his poem, "We Wear the Masks." After a short historical introduction, class members conduct a series or readings, marking up the text and...

There's only one way to multiply, right? Not when it comes to polynomials. Reach each individual by incorporating various representations to multiplying polynomials. This lesson approaches multiplying polynomials from all angles. Build...

Teach solving for unknowns through a problem-solving approach. The grouping of five lessons progresses from finding an unknown through simple reasoning to solving simultaneous equations involving three and four variables. Each lesson...

What happens next? Work on story sequence with a lesson that prompts kids to put a story back in order. Additionally, they discuss what would happen if one event was missing from the sequence.

Improve reading comprehension with a set of ESL worksheets. Kids read through various passages, note which facts are true or false, mark their opinion on two statements, and write a short reply based on a writing prompt.
