⭐Welcome to the 2022-2023 School Year!!✏️

Hi there!  I'm so excited you're here because there's going to be some great things happening!  There will be tons of learning and brain growing since I strive to build a thinking classroom.  This might sometimes make you feel uncomfortably frustrated but don't worry, we are in this together.  I know you won't give up and neither will I.  Let the LEARNING begin!
Hi!  I'm Cindy!  I'm from here, Crystal City,  I graduated from The University of Texas at San Antonio (GO RUNNERS!), I love photography, and this is my 10th+ year teaching!  My philosophy?  Lead every day with kindness and communication.  Understanding my students' thinking, and how they learn, and fostering an environment of thinkers is my top priority.
MATH: Place Value Relationships

Dear Parents, Your child is about to explore place value up to 100,000. To master this skill, they will build on their knowledge of place value from second grade. In second grade, your child learned how to compose and decompose numbers up to 1,200 as sums of thousands, hundreds, tens, and ones. As your child extends their knowledge of this concept throughout third grade, they will learn the following concepts

The value of a digit depends on the position in the number–
○ For example:  hundred thousand  ten thousand    thousand,  hundreds    tens    ones
How to accurately read, write, and say numbers by their place value–
○ For example:125,789 is written as one hundred twenty-five thousand, seven hundred eighty-nine
Use the knowledge of place value to add, subtract, multiply, and divide–
The relationship of place value digits–
○ The tens place is 10 times as much as the ones place
○ The hundreds place is 10 times as much as the tens place, or 100 times as much as the ones place

While working with your child at home, the following vocabulary terms might be helpful in your communication
about how to identify and represent place value up to 100,000. These are terms your child will be encouraged
to use throughout our explorations and during our math chats, which are short, whole-group discussions at the
conclusion of each activity.

Terms to Know
digit: any of the numerals 0-9
model: something created to copy how a real-world thing works, using equations or other math concepts
expanded notation: an expression showing the specific place value of each digit by
multiplying each digit by its place value example: (2x100) + (3x10) + (7x1)  equals 237
place value: the value of a digit based on its position in a number; position determines value

We will do many explorations in class to help your child learn these concepts from firsthand experiences.
Encourage your child to share these experiences with you and to teach you what he or she has learned. Ask
your child to identify examples of what he or she is learning in everyday life.

Thank you for your support as your child begins this new learning adventure.
SCIENCE: Introduction: Working Like a Scientist
In this unit, students will learn to use scientific processes, safe practices, and their science notebooks to investigate scientific concepts and describe their findings.
