About this class 🌸 Unit 1: This unit focuses on the following question: How are numbers read, written, compared, ordered, and rounded using place value? 🌸 Unit 2: This unit focuses on the following questions: How can sums and differences be estimated and found mentally? Can addition and subtraction be done on the number line? 🌸 Unit 3: This unit focuses on the following questions: How are numbers read, written, compared, ordered, and rounded using place value? 🌸 Unit 4: This unit focuses on the following question: What are different meanings of multiplication, including how addition and multiplication are related? 📆How is this class structured? This is a flex unit. I will post new instructional materials each week. The duration of each video is 7-10 min long. Students are expected to watch the video provided and answer the quiz that follows the instruction. 🚨Can I earn credit for this class? Students who complete the full course (and their assignments) can submit this documentation and apply for credit at their local school. Many schools also offer an option to test out of this class and place into other higher math units. 🚨I struggle in math, can I join this class? Absolutely! Remediating students in math is one of my specialties. 🎓 About the instructor I come to you with over 15 years of experience in STEM education. I am a certified educator in 6 different States. I hold a Bachelor's Degree of Science with distinguished honors. In addition, I hold a Masters Degree Science Education and Doctorate of Philosophy in Teaching Learning and Culture with a specialization in Science and Mathematics Education. You never stop learning! I became a teacher by choice. Teaching young minds has been one of the best things that has happened to me. I love to learn as much as I love to teach! 📆Class assignments Each lesson is followed by an optional assignment that will help students to reinforce the concepts learned during class. 👏🏻Assessments Summative assessments will be optional and available to students. The goal is to provide students with exposure to what a standardized assessment looks like without adding the anxiety that comes with testing. Student achievement will be measured formatively in the form of discussions, and assignments. 🚨Additional Resources You need two things for this class: A notebook and a pencil. Dr. V. will provide you with access to readings, slide decks, vocabulary lists, and practice problems after each class. 🚨Who normally takes this class? This class is for students who have completed 2nd grade math. Here are the Units that I will cover in this class: 🌸Unit 1: Numeration Lesson 1.1: Representing Numbers Lesson 1.2: Ways to Name Numbers Lesson 1.3: Greater Numbers Lesson 1.4: Place Value Relationships Lesson 1.5: Comparing Numbers Lesson 1.6: Ordering Numbers Lesson 1.7: Counting Numbers Lesson 1.8: Rounding on the Number Line Lesson 1.9: Problem Solving: Writing to Explain 🌸Unit 2: Number Sense: Adding and Subtracting Whole Numbers Lesson 2.1: Addition Properties Lesson 2.2: Using Mental Math to Add Lesson 2.3: Using Mental Math to Subtract Lesson 2.4: Estimating Sums Lesson 2.5: Estimating Differences Lesson 2.6: Relating Addition and Subtraction Lesson 2.7: Adding and Subtracting on a Number Line Lesson 2.8: Problem Solving: Use Representations 🌸Unit 3: Developing Proficiency: Adding and Subtracting Whole Lesson 3.1: Adding with an Expanded Algorithm Lesson 3.2: Models for Adding 3-Digit Numbers Lesson 3.3: Adding 3-Digit Numbers Lesson 3.4: Adding 3 or More Numbers Lesson 3.5: Subtracting with an Expanded Algorithm Lesson 3.6: Models for Subtracting 3-Digit Numbers Lesson 3.7: Subtracting 3-Digit Numbers Lesson 3.8: Subtracting Across Zero Lesson 3.9: Problem Solving: Draw a Strip Diagram, Write an Equation 🌸Unit 4: Multiplication Meanings Lesson 4.1: Multiplication as Repeated Addition Lesson 4.2: Arrays and Multiplication Lesson 4.3: Skip Counting on the Number Line Lesson 4.5: Writing Multiplication Stories Lesson 4.6: Problem Solving: Two-Step Problems

Lesson 1.1: Representing Numbers
Students read and write 3- and 4-digit numbers. They learn that our number system is based on groups of 10, all numbers are made from digits, and a place value is the value of the place a digit has in a number. Students show numbers with place-value blocks. They write 3- and 4-digit numbers in standard form, expanded form, and word form. Students learn to use a place-value chart. They solve problems to demonstrate their understanding. 1 作業

Lesson 1.2: Ways to Name Numbers
Learners use place value to name numbers in different ways. Learners name numbers as so many thousands, so many hundreds, so many tens, and so many ones. They name some numbers, including years and addresses, using thousands and hundreds, and only hundreds. They also name some numbers using only tens and only ones. Throughout the lesson, learners use place-value blocks to help them solve problems. 1 作業

Lesson 1.3: Greater Numbers
Students read and write numbers in the ten thousands and hundred thousands. They learn how a number s digits are grouped in periods for ones and thousands. Learners use a place-value chart to represent numbers in standard form, word form, and expanded form. They use place value to show different ways to compose and decompose numbers. 1 作業

課 4:
Lesson 1.4: Place Value Relationships
Students learn how digits within a multi-digit whole number relate to each other by their place value. Learners analyze the values of different digits and recognize that when two digits next to each other in a number are the same, the value of the digit on the left is ten times that of the digit to the right. Students write place values for given digits in numbers through six digits to verify place value relationships. 1 作業
