Mathematical Expression Teacher Resources

High Schoolers complete a variety of activities as they examine the ethics of (and take a position concerning) genetically modified organisms in the field of agriculture. They complete a PowerPoint demonstration to go along with the unit.

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!).

Young scholars explore satellite data and graphing. In this weather data analysis math and science lesson, students analyze NASA satellite data to draw conclusions about geographical areas where precipitation might have happened. Young...

How different can 3-D and 2-D really be? An engineering resource provides an explanation about the importance of two-dimensional technical drawings. Several samples show how to create multi-view drawings from pictorials and vice-versa....

Students solve linear equations and identify the unknown. In this algebra lesson, students define a variable and use addition, subtraction, multiplication and division to solve. They change the equation depending on the value of the...

Begin your next algebra unit with this introductory lesson on variables and algebraic expressions. This plan requires a SMART board and includes a SMART notebook file. The file contains a guiding question and two learning activities that...

Collaborate to research and share. Doesn't that sound great? Learners explore algebraic expressions, use Algeblocks to examine and compare numerical and variable expressions, and apply the distributive property. Examples and worksheets...

Prealgebra apprentices read seven phrases and write an expression for each. The printable version of the learning exercise is not very attractive; it has the standards information printed at the top. The problems are arranged in a table...

Solve problems using integration and derivatives. By using calculus, learners will analyze graphs to find the extrema and change in behavior. They then will identify the end behavior using the derivatives. Activities and handouts are...

There are a number of activities here that look at representing data in different ways. One activity, has young data analysts conduct a class survey regarding a new radio station, summarize a data set, and use central tendencies to...

This online instructional activity can be printed, projected on the board, or used as example problems for the class to solve. They write equivalent expressions for a set of given equations, 14 total. This page contains an answer link...

Given an algebraic expression, write a word problem. Usually it's the other way around where you have a word problem and need to write an algebraic expression. But, this is a good skill to have because it would mean that one has a good...

Fifth graders work on the different possibilities of reaching the number 100. The class is divided into homogeneous groups for cooperative learning. The lesson plan uses discussion questions to help with problem solving.

Explore the concept of the equals symbol. In this mathematical symbols lesson, learners discover the meaning of the equals sign (symbol). They also construct addition and subtraction sentences to understand the concept of equal parts.

Middle-school mathematicians identify the need for scientific notation. Learners convert large and small numbers into scientific notation. Students review the powers of ten and write them on the board in standard form and scientific...

Who made more money in the stock market, Brad or Ariel? Brad's stock went up, but Ariel's stock fluctuated up and down. Set up an inequality to solve this one. Ariel will have several terms as her stock fluctuated and Brad has a single...

Just watch this video for a very thorough explanation, step-by-step, on how to work with negative exponents. The instructor explains how it is possible that negative exponents and inverses and fractions are connected in this situation....

In this algebra activity, students learn how to evaluate algebraic expressions using the order of operations. They then solve 12 problems using what they learned.

For this algebra activity, 9th graders rewrite word problems into algebraic sentences. They define sum, difference, quotient and factors. There are 5 word problems with an answer key.

The order of operations is compared to punctuation in a sentence: it makes the meaning clear. After two example problems are solved according to a four-step format, your math class evaluates 12 expressions on their own. Learners could...

Students examine linear equations. In this functions and algebra lesson, students write equations in the slope-intercept form. They enter data in a graphing calculator, examine tables, and write linear equations to match the data.

High schoolers solve equations by writing expressions. In this algebra lesson, students identify the different values for each variable. They use the navigator to see how to solve equations.

In this algebra learning exercise, students rewrite sentences into algebraic equations using variables and solve for the unknown. There are 10 interactive questions with an answer key.

Learners of many ages use the Visual Thesaurus to help them understand the language of math. They work in groups to explore the multiple meanings of common math terms. Pupils come up with examples of the words in mathematical and other...
