Algebra Balance Scales

- Most of the keys have fallen off the calculator, but you have to make certain numbers using the keys that are left.

ArithmeTiles

- Use the four operations and numbers on neighboring tiles to make target numbers.

Choose a Math Operation

- Choose the mathematical operation(s) so that the number sentence is true. Practice the role of zero and one in basic operations or operations with negative numbers. Helps develop number sense and logical thinking.

Order of Operations Quiz

- A 10-question online quiz that includes two different operations and possibly parentheses in each question. You can also modify the quiz parameters yourself.

The Order of Operations Millionaire

- Answer multiple-choice questions that have to do with the order of operations, and win a million. Can be played alone or in two teams.

Exploring Order of Operations (Object Interactive)

- The program shows an expression, and you click on the correct operation (either +, -, x, ÷ or exponent) to be done first. The program then solves that operation, and you click on the
*next*operation to be performed, etc. until it is solved. Lastly, the resource includes a game where you click on the falling blocks in the sequence that the order of operations would dictate.

Order of Operations Practice

- A simple online quiz of 10 questions. Uses parentheses and the four operations.

Fill and Pour

- Fill and pour liquid with two containers until you get the target amount. A logical thinking puzzle.

Balance Beam Activity

- A virtual balance that poses puzzles where the student must think algebraically to find the weights of various figures. Includes three levels.

Algebraic Expressions Millionaire

- For each question you have to identify the correct mathematical expression that models a given word expression.

Escape Planet

- Choose the equation that matches the words.

Expressions: Expressions and Variables Quiz

- Choose an equation to match the word problem or situation.

Equation Match

- Match simple equations that have the same solution.

Algebraic Reasoning

- Find the value of an object based on two scales.

Algebra Puzzle

- Find the vale of each of the three objects presented in the puzzle. The numbers given represent the sum of the objects in each row or column.

Battleship

- An interesting game where the student must choose the right solution to a 1-step equation every time she hits an enemy ship. Although some of the equations involve negative solutions, the game is multiple-choice, so it's possible to guess the solution, even if the student isn't familiar with negative numbers.

Algebra Meltdown

- Solve simple equations using function machines to guide atoms through the reactor. But don't keep the scientists waiting too long or they blow their tops. Again, includes negative numbers.

Words into Equations Battleship Game

- Practice expressions such as quotient, difference, product, and sum.

Balance when Adding and Subtracting Game

- The interactive balance illustrates simple equations. Your task is to add or subtract x's, and add or subtract 1's until you have x alone on one side.

Algebra Balance Scales

- Similar to the one above, but you need to first put the x's and 1's in the balance to match the given equation. - only positive numbers
