Students use numeric operations and concepts to describe, analyze, communicate, synthesize numeric data, and to solve problems.

Explore a basic pattern to practice writing expressions. In collaborative groups, learners examine a contextual pattern and write an expression to model it. The task encourages groups to describe the pattern in multiple ways.

Eric and Leila's video game scores are the inspiration for writing equations with parenthesis. The numbers are purposefully large to deter the class from calculating them: rather this activity meets the standard that asks 5th graders to...

Your class is asked to use inverse operations to solve eleven equations for unknown variables or to rearrange formulas to highlight a quantity of interest. By using the same reasoning as solving one- and two-step equations, algebra...

Can Dan make a conjecture about dividing fractions with the same denominators? That is what your scholars are to determine. They must show that if the statement is true, they understand how the quantities were determined, and how...

Think inside the box with KenKen® puzzles to provide some problem solving practice. These puzzles are similar to Sudoku, but require computation inside designated boxes. There are multiple puzzles with a range of difficulties to...

Listen to the sound of children's fingers flying across their keyboards as they perform these fun typing lessons. From creating alphabet books and multimedia presentations to researching presidents and writing class...

Parentheses are an important tool in the algebraic toolbox in regard to the structure of the algebraic equation. They are the beginning of the standard order of operations rule, the P in PEMDAS. The central question...

It is important for the algebra learner to understand the use of parentheses. Mathematicians of all levels can make errors with nested parentheses. This will give them some practice. It makes for a good class starter or quick assessment.

Hooray for chocolate chip cookies! Ask your mathematicians to triple a chocolate chip cookie recipe and then reduce the recipe by one-fourth. Your class may need two days to complete, tripling the recipe the first day and reducing the...

Reinforce the concept of comparing fractions with a hands-on, two-player game that calls for a visual model, score board, and dice. Players roll dice to acquire their given fraction, create the fraction using fraction tiles, then...

Test your mental math skills in arithmetic. How many questions can you answer in one minute? Good luck!

College professor Dan Bach offers a review of various basic topics in arithmetic, pre-algebra, and algebra. Order of operations, exponents, square roots, variables, and combining terms are just a few of the many topics covered.

A tutorial will guide you through the rules and steps for adding, subtracting, multiplying, and dividing real numbers, as well as evaluating numeric expressions and using order of operations. Contains step-by-step solutions to example...

A tutorial that covers evaluating and simplifying different types of expressions. Find definitions and examples of exponential notation, order of operations, variables, and algebraic expressions, and complete practice exercises through...

This Math Page tutorial explains how to change a fraction to a decimal and features a practice section at the end of the lesson.

Use this "math solver" to help you understand and evaluate any numerical expression that does not involve variables. Simply type your expression in, and allow this website to provide step-by-step instructions on how to evaluate the...

It's a mathematician's dream come true. An easy trick for checking mathematical computations, without a calculator! Believe it or not, it works with all four operations.

In Spanish. This site contains many games for practicing mental numerical calculation of basic operations.

Use this site to practice writing the digits for a number when you see it written out using words. Then check your accuracy.
