Geometry-Volume-Solids-lite Free - The lite version of this app provides a quick way to learn and calculate volume of solids. There are six computer-animated videos on the volume of the cube, rectangular solid, cylinder, sphere, cone and pyramid. The paid addition is $1.99. It includes videos on the cube, cylinder, sphere, cone and pyramid.

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

- Ratios and Proportional Relationships - Analyze proportional relationships and use them to solve real-world and mathematical problems.
- The Number System - extend previous knowledge using the four operations with fractions and the ability to divide and multiply rational numbers.
- Expressions and Equations - Use properties of operations to generate equivalent expressions.
- Geometry - Draw, construct and describe geometrical figures and describe the relationships between them.
- Statistics and Probability - Ability to use random samplings and make inferences about populations, investigate chance processes and develop, use, and evaluate probability models.

7th grade math testing prep $2.99; Teacher upgrade $4.99- Covers the Core Standards from advanced problem solving, fractions, probability, and statistics to logical calculations.
