Functions are special types of relations, but what makes them so special? Pupils use an interactive to slide a vertical line across six different graphs. Ten challenge questions then assess understanding of functions.

What does it mean to take the mean of the mean? An easy-to-use interactive has users adjust the mean ages of different samples. Finding the average of these sample means gives an estimate of the population mean.

Limits are made easy through graphs and tables. An easy-to-use interactive lets users change a function on a coordinate plane. They relate graphs and tables to the limit at a specific value.

A one-sided limit is no less important than a two-sided limit. Young mathematicians use an interactive to match limit notation to graphs. The exercise requires interpreting how one-sided limits connect to features of graphs.

There are an infinite number of reasons to use the resource. Scholars drag vertical and horizontal lines to the graph of a rational function to identify all asymptotes. They investigate the connection between asymptotes and limits to...

Building trigonometric basics here will last a mathematical lifetime. Learners expand on the previous lesson in a 36-part series by examining relationships between the sine and cosine of complementary angles. They also review the...

So a cylinder does not have to look like a can? By expanding upon the precise definition of a rectangular prism, the lesson develops the definition of a general cylinder. Scholars continue on to develop a graphical organizer...

How are systems related? Build on your pupils' previous knowledge of solving systems of equations by introducing systems of inequalities. Learners explore similarities between systems of equations and inequalities to make a strong...

Log the resource on logarithms for future use. Learners review and explore properties of logarithms and solve base 10 exponential equations in the 12th installment of a 35-part module. An emphasis on theoretical definitions and...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Seventh graders create three dimensional works of art from two dimensional plans, develop skills in papier-mach?? technique, utilize elements and principles of design to create 3-D form, and develop math/strategy skills in playing the...

Students apply information regarding simple machines along with the math concept "ratios." The teacher introduces the concept that technology is the application of scientific knowledge and mathematics concepts to solve a problem. This is...

Learners identify obtuse and acute angles in comparsion to a right angle. They identify obtuse, acute, and right angles. Pupils use "Shape Measure" to construct obtuse, acute, and right angles. They review line segements to locate right...

Young mathematicians compare two fractions with like denominators and then move to the next level to compare fractions with unlike denominators. They will first try to use mental math to make educated guesses. There are a few guidelines...

Students practice their multiplication facts by reinforcement and repetition. Students write facts in their math journals, and use labeled soccer ball and deck of cards to practice multiplying by "number of the day." Play continues until...

In this density worksheet, students review how to rearrange the equation for density to solve for mass or volume. Then students complete 4 problems.

Why is calcium good for the body? Where is it stored? Young chefs discover the importance of calcium and review a list of foods that are rich in the material. They then make delicious smoothies high in calcium! Teaching kids how to...

This algebra instructional activity reviews writing polynomials in standard form from factored form, looks at the graphs of polynomials of degree higher than two, and identifies the zeros of polynomials using the Factor Theorem and...

What a great classroom resource! The intention of this lesson plan is to show that real-world math can and should be applied to the community in which your high schoolers reside. The class relates properties of equations to solving for...

Field trip! The class will review what they know about organisms that dwell in freshwater ponds, then trek down to the old water hole to collect specimens for examination. This includes several web links, useful tips, and an excellent...

Three sets of objects create arrays for learners to count: will they discover strategies to make their job easier? Each array has between 105 and 120 objects in rows. Have learners do the first one, then review their strategies. Did...

If you're looking for guided addition problems, here is a practice list of 30. All of these have two double-digit addends, and many require regrouping. There are three example problems for learners to reference, each of which also...

The steps are laid out in these fraction addition practice problems. Scholars add fractions with common denominators, making sure to reduce to the simplest form. For all of these, that means turning a simplified improper fraction into a...

Give mathematicians 39 chances to practice adding fractions, most of which involve mixed numbers. There are three examples to get them started, and scholars should be encouraged to reduce answers when necessary. Not for beginners, these...
