# Apps for Common Core Math Standards, Grades 4-5

The standard includes five components:

• Operations and Algebraic Thinking- expanding the topic to include gaining familiarity with factors and multiples, generate and analyze patterns.
• Number and Operations in Base Ten- increase the ability to use place value to perform multi-digit arithmetic.
• Number and Operations- Fractions- understanding fraction equivalence and ordering, understand decimal notation for fractions and compare decimal fractions.
• Measurement and Data- solve problems of measurements from a larger unit to a smaller unit, geometric measurement.
• Geometry- draw and identify lines and angles.

ilivemath-oceans \$4.99 - I have mentioned apps in this series in other blogs. This app generates one- and two-step word problems; it has three levels of difficulty including addition, subtraction, fractions and circle geometry. The series includes three additional apps that cover the same areas of math.

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

4th grade math testing prep \$2.99 - An inclusive app that addresses identification of patterns, decimals, fractions, measurement, variables, word problems, angles, algebra and more.

Geometry 4 Kids \$.99 - Appropriate for all elementary grades. It covers line segments, rays and angles, congruence and transformations, critical thinking and more.
