Arithmetica

Arithmetica is a comprehensive Chrome extension designed to enhance the teaching and learning of arithmetic, catering primarily to middle school (Cycle 4) and high school students.

It is divided into three key components:

1. Activities: Includes quizzes to assess prior knowledge on division vocabulary and divisibility, the Sieve of Eratosthenes for exploring prime numbers, gear and wheel activities to understand mechanisms, fraction simplification exercises involving prime factor decomposition, and an exploration of the Collatz conjecture through computational tasks.

2. Toolbox: Provides practical tools for arithmetic operations such as determining divisors of integers (up to 9 quintillion), primality tests with details on factors, prime factor decomposition, analysis of two integers for common divisors, GCF, LCM, and Bezout coefficients.

3. Serious Games: Engages students with interactive games like Divisibox (dividers and multiplication tables), Game Prime (speed-based prime number identification), and Juniper Green (a strategic numerical game adaptable for different play modes and grid sizes).

This extension is ideal for educators seeking interactive and educational resources to support arithmetic learning in classroom and remote settings.
