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.
thumbnail
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.
thumbnail
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.
thumbnail
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.
thumbnail
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.
thumbnail
Converter
Converts fractions to decimals and decimals to fractions. Observe the relationships between fractions and decimals.
thumbnail
Equivalent Fractions Finder
Visually represent two unique fractions that are equivalent to a given fraction. T
