📆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.

課 1:
Lesson 9.1: Arrays and Using an Expanded Algorithm
Students learn different ways to multiply a two-digit number by a one-digit number. One way is to use arrays of place-value blocks. The other way is to use the expanded algorithm. With the expanded algorithm, the two-digit number is broken apart into tens and ones, and then each part is multiplied by the one-digit number. The partial products are added together to find the final product. 1 作業

Lesson 9.2: Connecting the Expanded and Standard Algorithm
Students learn to record two-digit by one-digit multiplication problems using the standard algorithm. They learn the standard multiplication algorithm is a common way to record multiplication and is just a shortened way of recording the information in the expanded multiplication algorithm. With the standard algorithm, students solve problems without recording partial products. They regroup, as needed, as they record the product. 1 作業

Lesson 9.3: Multiplying 2-Digit by 1-Digit Numbers
Students learn to use the standard multiplication algorithm to multiply two-digit numbers by one-digit numbers. Students first multiply the ones, and regroup if necessary. Then they multiply the tens and add any extra tens. Students use estimation to check their answers for reasonableness. Students use the standard algorithm to solve real-world and mathematical multiplication problems. 1 作業

Lesson 9.4: More Multiplying 2-Digit by 1-Digit Numbers
Students learn to solve comparison multiplication problems using the standard algorithm. They estimate the product to check their answers for reasonableness. Students use the standard algorithm to solve real-world and mathematical problems, including those that involve multiplication as comparison. 1 作業
