# Apps for Common Core Math Standards, Grades 6-8

The **sixth grade** standard includes five components:

- Ratios and Proportional Relationships - Understand ratio concepts and use ratio reasoning to solve problems.
- The Number System - Extend previous understanding of fractions including multiplying and dividing fractions, compute fluently with multi-digit numbers and find common factors and multiples.
- Expressions and Equations - Reason about and solve one-variable equations and inequalities.
- Geometry - Solve real-world and mathematical problems involving area, surface area, and volume.
- Statistics and Probability - Develop understanding of statistical variability.

6th Grade Math Testing Prep $2.99; Teacher upgrade $4.99 - This app covers all of the core standards, allowing students to move at their own pace with quizzes to evaluate student understanding. Topics include: ratios, probability, statistics, algebra, geometry, and multiple step procedures. The upgrade for teachers allows teachers to enter as many students as needed, set the number of questions, and review scores and track student improvement.

Algebra Touch $2.99 - Current material covers: Simplification, Like Terms, Commutativity, Order of Operations, Factorization, Prime Numbers, Elimination, Isolation, Variables, Basic Equations, Distribution, Factoring Out, Substitution, and 'More Advanced' mode.
