Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Four inequality statements are given for the same two negative numbers. The resource is a good practice for pupils to interpret statements of inequalities relative to the position on the number line. The objective is for pupils to...

Add a festive flair to math instruction on Cinco de Mayo with a activity designed to reinforce division, finding unit prices, and solving word problems. 

What better way to learn about fractions than with a couple pizzas? Help Jessica figure out how much of the pizza she has eaten, while teaching your class that fractions refer to a specific whole amount. This problem will be challenging...

Circles, lines, dots, boxes: graphs come in all shapes in sizes. Scholars learn how to make a bar graph using univariate data. They also analyze data using those bar graphs.

In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

Develop young mathematicians' fluency with subtracting mixed numbers using this collection of practice problems. Addressing the subtraction of mixed numbers with and without regrouping, this resource clearly models each process...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the...

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry lesson. Through a series of problem solving exercises, children use their math knowledge to design different-sized garden...

Why was the obtuse angle upset? Because it was never right! A valuable resource is loaded with background information on types of angles and lines. Learners review the characteristics of parallel, perpendicular, and...

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

Root for your pupils to learn about roots. Young mathematicians first review the meaning of squares and square roots. They then use this knowledge to simplify square roots of monomials with variables.

How do you put something as large as the universe in perspective? Use a series of scale experiments. Classmates collaborate around four experiments to examine the scale of the earth-moon system, our solar system, the Milky Way galaxy,...

How do 2-D properties relate in 3-D? Lead the class in a discussion on how to draw and see relationships of lines and planes in three dimensions. The ability to see these relationships is critical to the further study of volume and...

In this integers worksheet, students solve and complete 8 various types of word problems. First, they read each problem and determine from the information what they are looking for. Then, students determine the operations necessary to...

Graphing systems of linear inequalities is the focus of this worksheet. Problems range from checking solutions of inequalities, graphing systems of two inequalities, and graphing systems of three inequalities. Graphing horizontal lines,...

Use a worksheet to go over the basic concepts of relations and functions. Included are clear definitions and examples of relations, domain and range, and functions and the vertical line test.  However, the problems are pretty...

Start this activity with a brief description of how to solve absolute value inequalities. A space is provided to help classify the inequalities into types (greater than, less than, or equal to) and for learners to show how to graph their...

Use this worksheet as a warm up, a refresher exercise, or a practice after a more detailed lesson on graphing linear inequalities in two variables. Start with boundaries that are horizontal or vertical, then move into graphs with...

In this calculus worksheet, 12th graders use integration to find the area under a graph. They use integration to solve real world problems. There are 4 different sections with their own problems.

In this Pythagorean theorem activity, 9th graders solve and complete 8 different types of problems. First, they go to the given website and copy the picture shown. Then, students draw a right triangle using the straight line between the...
