Welcome to 3rd Grade Math!

Hello new math students and parents and welcome to a great new year of mathematics!  May Watts is entering its fifth year of math instruction using the Common Core Math Standards and I have to say, I am a true fan of the instructional shifts.  Students are learning to make real world math connections and think rather than just compute.  I created this math blog to give both students and parents a place to understand, learn, practice and have fun with the standards.  If you click on the Common Core Apple, it will give you a 3-minute rationale on the shift to Common Core Standards. Additionally,  if you click on any of the pictures, they will take you to live links a well.   I try really hard to make math class a safe place to question and explore.  Please feel free to e-mail or call with any questions or concerns you might have.

Quarter 1
To begin the math year, we will be creating our math community. We will discuss the way we use math in everyday life and notice the numbers around us. Also,  will discuss expectations, and establish rules and procedures for our math time to create the best climate for learning.  After that,  we will move to learning...

Number Sense

This is a prerequisite unit that will focus on number sense. Students will understand place value within 1,000 and identify addition and subtraction patterns. Students will demonstrate an understanding of standard and expanded notations. Sequencing and ordering numbers will be reviewed.

Learning Targets:

• Students will understand that digits have value.
• Students will understand that numbers can be written in different forms.
• Students will understand there are patterns when adding and subtracting.

Vocabulary/Concepts 

• Vocabulary - Place value, digit, pattern, standard notation, expanded notation, word form, ordering, sequencing.
• Mathematical operations (Addition, Subtraction, Multiplication, Division).
• Arithmetic Patterns 

Unit 1

This unit's main focus is multiplication and division and solving problems with units of 2-5 and 10. The students will know the relationship between multiplication and division. They will be able to use manipulatives and pictures to solve a variety of problems. Knowing their facts fluently is an ongoing skill. Story problems are used for multiplication and division throughout the unit.

Learning Targets:

• Students will understand there is an inverse relationship between multiplication and division.
• Students will understand there are multitudes of strategies to solve and represent multiplication/division problems.
• Students will understand there are patterns when using four operations.

Vocabulary/Concepts

• Vocabulary - Array, Associative Property, Commutative Property, Distributive Property, Dividend, Divisor, Factor, Product, Quotient.
• From Memory, some Products of two One-Digit Numbers. (0,1,2,3,4,5 facts).
• Symbols to Represent an Unknown Number
• Multiplication & Division are related operations.
• Arithmetic Patterns (Even & Odd Numbers, Patterns in Multiplication Table, Patterns regarding Multiple and Division)
• Strategies for Multiplication & Division.
