Number and Operations

Another Hilbert Curve Generator	Students work step-by-step through the generation of a different Hilbert-like Curve (a fractal made from deforming a line by bending it), allowing them to explore number patterns in sequences and geometric properties of fractals.
Arithmetic Four	A game like Fraction Four but instead of fraction questions the player must answer arithmetic questions (addition, subtraction, multiplication, division) to earn a piece to place on the board. Parameters: time limit, difficulty level, types of questions. Arithmetic Four is one of the Interactivate assessment games.
Arithmetic Quiz	Similar to Arithmetic Four: Arithmetic Quiz gives the user randomized questions to answer on arithmetic with whole numbers and integers. Parameters: Level of difficulty and types of questions. Arithmetic Quiz is one of the Interactivate assessment quizzes.
Bounded Fraction Finder	The same as "Bounded Fraction Pointer" but there is no arrow to help the user determine the value of the fractions between the two endpoints. Bounded Fraction Finder is one of the Interactivate assessment explorers.
Bounded Fraction Pointer	Graphically determine the value of two fractions you have chosen (which are represented as points on a number line). Graphically find a fraction whose value is between your two fractions (using an arrow on the number line as a guide), then determine its value. Bounded Fraction Pointer is one of the Interactivate assessment explorers.
Caesar Cipher	Create your own affine cipher for encoding and decoding messages. Input your own constant and multiplier, then input a message to encode.
Caesar Cipher II	Encode and decode messages to determine the form for an affine cipher. Input a message to encode, then input your guesses for the constant and multiplier. Caesar Cipher II is one of the Interactivate assessment explorers.
Caesar Cipher III	Decode encrypted messages to determine the form for an affine cipher, and practice your reasoning and arithmetic skills. Input your guesses for the multiplier and constant. Caesar Cipher III is one of the Interactivate assessment explorers.
Cantor's Comb	Learn about fractions between 0 and 1 by repeatedly deleting portions of a line segment, and also learn about properties of fractals. Parameter: fraction of the segment to be deleted each time.
Clock Arithmetic	Work with various types of clocks in order to learn about modular arithmetic operations. Parameters: Number of hours on the clock.
Coloring Multiples in Pascal's Triangle	Color numbers in Pascal's Triangle by rolling a number and then clicking on all entries that are multiples of the number rolled, thereby practicing multiplication tables, investigating number patterns, and investigating fractal patterns. Coloring Multiples in Pascal's Triangle is one of the Interactivate assessment explorers.
Coloring Remainders in Pascal's Triangle	Color numbers in Pascal's Triangle by rolling a number and then clicking on all entries that have the same remainder when divided by the number rolled, thereby practicing division and remainders, investigating number patterns, and investigating fractal patterns. Coloring Remainders in Pascal's Traingle is one of the Interactivate assessment explorers.
Comparison Estimator	Compare two sets of objects, using estimation to determine which is greater. Estimate a number of objects, the length of a line, or the area of a shape. Parameter: error tolerance. Comparison Estimator is one of the Interactivate assessment explorers.
Converter	Converts fractions to decimals and decimals to fractions. Observe the relationships between fractions and decimals.
Equivalent Fractions Finder	Visually represent two unique fractions that are equivalent to a given fraction. The fractional value is shown on a number line after you check to see if your fraction is correct. Equivalent Fraction Finder is one of the Interactivate assessment explorers.
Equivalent Fractions Pointer	Visually represent two unique fractions that are equivalent to a given fraction. The fractional value is shown on a number line as you color in the fraction. Equivalent Fraction Pointer is one of the Interactivate assessment explorers.
Estimator	Practice estimation skills by determining the number of objects, the length of a line, or the area of a shape. Parameters: error tolerance. Estimator is one of the Interactivate assessment explorers.
Estimator Four	Play a "Connect-Four" style game, earning a game piece each time you answer an estimation question correctly. This game asks the players to estimate the answer to addition, multiplication, and percentage questions. Choose difficulty level, question types, and time limit. Estimator Four is one of the Interactivate assessment games.
Estimator Quiz	Test your estimation skills by answering questions. This quiz asks you to estimate the answer to addition, multiplication, and percentage questions. Choose difficulty level, question types, and time limit. Estimator Quiz is one of the Interactivate assessment quizzes.
Factorize	Visualize factors through building rectangular areas on a grid. First enter all the factorizations of a number, then draw each factor set as an area on the grid. Factorize is one of the Interactivate assessment explorers.
Factorize 2	Visualize factors through building rectangular areas on a grid. As you draw each factor set on the grid, the factors will be listed. Factorize 2 is one of the Interactivate assessment explorers.
Fraction Finder	Graphically determine the value of two given fractions represented as points on a number line. Graphically find a fraction whose value is between the two given fractions, then determine its value. Fraction Finder is one of the Interactivate assessment explorers.
Fraction Four	Students play a generalized version of connect four, gaining the chance to place a piece on the board by answering questions about simplify fractions, converting fractions to decimals and percents, as well as algebra questions involving fractions. Parameters: Level of difficulty and question type. Fraction Four is one of the Interactivate assessment games.
Fraction Pointer	Graphically determine the value of two given fractions represented as points on a number line. Graphically find a fraction whose value is between the two given fractions (using an arrow on the number line as a guide), then determine its value. Fraction Pointer is one of the Interactivate assessment explorers.
