In this algebraic equations instructional activity, students solve and check ten algebraic equations. In the first 3 problems, they find the solution of the equation by using the substitution method. And in the last 7, students solve for...

A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

For this chemistry worksheet, students complete the reactions by drawing structures of major products, indicating important minor products. They also write the structure of the product and describe the stereo chemistry of the product.

What do you get when you combine precipitate reactions with puzzles? Maximize the engagement in a single replacement reactions lesson by incorporating fun puzzles. Chemistry scholars observe the reaction between several sodium halides...

In this linear equation worksheet, students solve five systems of linear equations using the substitution method.  Three examples with steps to solve are provided.

Students solve linear equations. In this algebra lesson, students use substitution to solve equations. They plug in the numbers for the missing variable and solve.

Students research The Nine Chapters on the Mathematical Art and Chinese contributions to mathematics using both print and non-print sources. From their research they create an illustrated table of contents for each chapter of the Nine...

True or false? Scholars determine the truth value of equations and inequalities through substitution. All values to use for substitution are given with each equation or inequality. This is the 24th lesson in a module of 36.

Substitution is still the method of choice to verify number sentences. The detailed lesson has young mathematicians determining conditions for when number sentences are true or false through substitution. They learn to express these...

Somehow 55 chemistry problems have been squished onto a single page! Don't assume that it is a mess, however. High school chemists write the products for different types of reactions. Then they identify the type of reaction in addition...

When is the last time you assigned your students only one problem? This seemly simple problem requires learners think like a mathematician and reason about how to solve this compound inequality in one variable. More than just using...

In this decimal equations instructional activity, students review the process to solving decimal equations, then use inverse operations to solve 4 problems, checking with substitutions.
