3rd grade Math
In this post I am going to look at 3rd grade math. What are the students supposed to know going into 3rd grade and what are they expected to learn.
What are the students expected to know going into 3rd grade:
1. Extended understanding of base-ten notation.
2. Fluent in addition and subtraction.
3. Able to use standard units of measure.
4. Able to describe and analyze shapes.

By 3rd grade the foundation should be laid and the students will begin to expand on their previous knowledge and really start building a solid understanding of more complex mathematical ideas and equations.
In 3rd grade the students will be expected to learn:
1. Understanding of multiplication and division, specifically strategies for multiplication and division within 100.
2. Understanding of unit fractions.
3. Understanding of rectangle arrays and an understanding of area
4. Describe and analyze two-dimensional shapes.

Below is a more in-depth look at the 3rd grade standards which has been taken from corestandards.org. This is a fantastic resource for understanding the common core standards.

In going over the 3rd grade curriculum I felt like it jumped quite a bit from 2nd grade. It reminded me of something my older daughters 3rd grade teacher told me once about reading in 3rd grade.
She said, "In 3rd grade the children are no longer learning to read, they are now reading to learn."
In feel that this is the case with math as well, they are now taking the foundation that they have learned and they are building upon it. They are no longer learning number basics, they are now taking number basics and applying them to more complex number problems. 3rd grade is such a key year for applying previous knowledge and using it to understand and problem solve while adding new knowledge.

Grade 3 Overview
Operations and Algebraic Thinking
- Represent and solve problems involving multiplication and division.
- Understand properties of multiplication and the relationship between multiplication and division.
- Multiply and divide within 100.
- Solve problems involving the four operations, and identify and explain patterns in arithmetic.
Number and Operations in Base Ten
- Use place value understanding and properties of operations to perform multi-digit arithmetic.
Number and Operations—Fractions
- Develop understanding of fractions as numbers.
Measurement and Data
- Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
- Represent and interpret data.
- Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
- Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures.
Geometry
- Reason with shapes and their attributes.
Mathematical Practices
- Make sense of problems and persevere in solving them.
- Reason abstractly and quantitatively.
- Construct viable arguments and critique the reasoning of others.
- Model with mathematics.
- Use appropriate tools strategically.
- Attend to precision.
- Look for and make use of structure.
- Look for and express regularity in repeated reasoning.
