A short video introduces the triangle that illustrates how to find any value given the other two in the density formula. Class members use the triangle to work several problems to find the mass, volume, or density of an object.

Provide learners with both the questions and the answers at the same time. They will consider each problem and then read how to solve it. There are two problems in which they are required to make 10 by completing the steps found in each...

Eighth graders combine like terms in this properties of variables lesson. Using named items (stars, moons and hearts), they combine like terms using variables. They use the distributive property to combine like terms. Finally, they write...

A thorough and professional appearance characterizes a activity on linear equations. Maturing mathematicians are taught to identify and exemplify linear equations with a single variable. They also classify equations according to the...

Classmates solve 18 different problems that are mostly word problems that apply algebraic expressions. They draw different combinations of masses on a scale that would balance. They also simplify expressions and solve for x in a number...

Your learners will be tantalized by this inquiry-based, collaborative activity as they discover how to write an equation that represents the height of an ice cream cone. Given the scenario based on the poem, "Eighteen Flavors," and...

For this variables worksheet, students are given seven experiments that they read and identify the independent variable, dependent variable, control group and standardizing variable.

Fourth graders examine the purpose of variables and identify the missing variable in open sentences. They observe the teacher solve a variety of problems, complete a worksheet as a class, and independently complete another worksheet. ...

In this experiment worksheet, students read over examples of different experiments and identify the control group, and independent and dependent variables. This worksheet has 20 short answer questions.

In this scientific methods worksheet, students identify the control group, independent variables, and dependent variables in 4 different experiment descriptions.

In this experimental design and measurement worksheet, students answer questions about independent and dependent variables, they write hypotheses, they identify instruments that measure mass, weight, and volume and they calculate the...

Students gather data on sports team and create a box and whisper plot. In this data collection lesson, students find the median, the quartile range, and relationships between variables.

In this solving equations worksheet, learners solve 14 short answer equations. Students isolate a given variable by multiplying or dividing.

Learners subtract or add a whole number to both sides of the equal sign for fourteen problems. They divide by either two or three to find the value of x. Since this worksheet is online, you can create a new problem set each time you use it!

In this polynomial worksheet, students collect like terms to add polynomials of multiple variables. Explanations and examples are provided prior to the exercise. This two-page worksheet contains ten problems.

In this fractions learning exercise, students follow directions to calculate a fraction of a number represented by decimals. Students follow four directions.

Here is a great set of eight scenarios that require the writing of a one-variable inequality and then solving to find the solution. This inequality word problem activity is then followed by the solutions to each of the eight problems.

In this linear equations worksheet, students solve and complete 20 different problems that include using the order of operations. First, they distribute to remove the parentheses and combine like terms. Then, students move variables and...

The sixteen problems in this resource present opportunities for pupils to practice substituting into algebraic expressions. Scholars evaluate algebraic expressions for given values of the variables. In a few cases, class members need to...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Common Core is all about getting your learners to open their minds and think about the why and how. This problem has them thinking about unknown numbers and their relationship with one another when we round and...

Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

Math whizzes explore dependent and independent outcomes. They determine the outcome of simple and compound events. Pupils complete tree diagrams to identify outcomes. They identify fair and unfair games. This two-page worksheet contains...

If you can multiply binomials, you can factor trinomials! This is the premise for a lesson on factoring. Pupils look for patterns in the binomials they multiply and apply them in reverse. Examples include leading coefficients of one...
