Here is a simple, yet clever lesson on how to teach the important concepts of greater than, less than, and equal to. Pupils write their names down on grid paper - one letter per box. They compare their names and find a name that is...

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

Attack and defend are the focus for this lesson, seventh in a series of 10. It basically pulls some of the skills together that have already been taught and allows the players to practice their specific skills in a one-on-one situation.

Puzzles are the formula for success in organic chemistry! Hydrocarbons abound in the first of two interactives involving basic organic molecules. The easy-to-use lesson is available online and in print form, so you can pick your delivery...

Young mathematicians find the area and perimeter of shaded shapes on a grid of unit squares. The sheets challenge class members to find the volume of various solid prisms. Each questions also includes the total value of suggest...

If pupils think the three types of rock are classic, punk, and hard, these puzzles offer gentle correction. Scholars match the type of rock to how it formed and an example in four grid puzzles. Each requires problem-solving and...

While scientists have identified seven states of matter, these puzzles cover the most common three. Scholars match the properties, particle motion, and particle picture to each type of matter. Three Sudoku-style puzzles review the data...

Is your class in a quandary over quantum numbers? Change things up by adding games to the mix! Science scholars discover the shape, number of electrons, and number of orbitals in the s, p, and d sub-shells using an interactive.

Here is an excellent cross-curricular lesson. Learners relate multiplication to area by making a grid on graph paper, and then creating the same grid in real space outside in the school yard.

While the periodic table looks complex, it is really arranged by only two variables, atomic number and electron configuration. The set of four puzzles focuses on groups 3, 4, 5, and 6 or 13, 14, 15, and 16, depending on your periodic...

Caustic soda helps break up clogs in drains in many homes. Scholars match 10 chemical names to their everyday names; for example, caustic soda is sodium hydroxide. Then, they complete three different grid puzzles practicing this skill.

Do solids, liquids, and gases even matter? Scholars match the state of matter to its particle picture, size and shape description, and description of the arrangement of the particles. Once they complete that activity, they complete a...

The United States consumes more oil than any other country, and its residents use 50 percent of that for transportation. Scholars match eight fractions of crude oil to their applications. Then, they fill in three logic puzzles reviewing...

Fats and oils often contain esters, which sometimes find their way into perfumes due to their pleasant smells. Scholars match the name of esters made from four different types of alcohol and four different types of carboxylic acids....

Two men want drinks and the first orders H2O. The second man orders H2O too, but he dies. Scholars apply their knowledge of H2O2 and other everyday chemicals during the activity. They match chemical formulas to common chemical names in a...

Students graph families of equivalent fractions and compare them by observing the slope of the line formed by each fraction family. They place fractions in ascending order by comparing the slopes of each line after several families of...

Fourth graders engage in a lesson that is about the concept of rounding decimals. They review place value and focus it upon the practice of rounding. Students use 10 base decimal grids or models to help make connections with the skill.

Where do the coordinates lead? As children brainstorm ways to find the location of different buildings, they learn about coordinate points and how to use them to locate areas on a grid or map. They practice using ordered pairs by playing...

Make enlargements with and without centers. Pupils work through seven problems dealing with dilations or enlargements. The first couple items are strict enlargements without centers, while the others have centers. Class members also...
