Tune in to learn about this course!
In this lesson, we review key vocabulary (factors, products, etc.), arrays, and the properties of multiplication.
In this video, we will review the Lesson 1 Activity on Multiplication and its Properties.
This video provides an introduction to several of the resources provided in this lesson for use throughout the course.
In this lesson, we discuss finding multiples of a given factor as well as finding the Least Common Multiple (LCM) of two factors.
In this video, we will review the Lesson 2 Activity on multiples and least common multiples.
In this lesson, we combine the concepts learned in the first two lessons to determine if a number is prime or composite. We also explore square numbers.
In this video, we will review the Lesson 3 Worksheet and Riddle Activity on Prime and Composite Numbers.
In this video, we will review the Lesson 3 Prime and Composite Chart Activity.
In this lesson, we will discuss the place and value of digits in a number up to the billions place. This will be super important when we jump into multiplying multi-digit numbers in the next few lessons!
In this video, we will review Lesson 4 Activity 1 focusing on place value.
In this video, we will review Lesson 4 Activity 2 focusing on place value in real world contexts.
In this video, I demonstrate how to use the game Hopscotch to practice place value.
In this lesson, we differentiate between the standard and expanded forms of numbers. Expanded form will help us to better understand the multi-digit multiplication methods we will be exploring next!
In this video, we review the Lesson 5 Activity on Standard and Expanded Form.
In this lesson, we will explore multiplying with base-tens. Not only is this a helpful trick in general, but it will allow us to check our work with estimation as we move forward.
In this video, we will review the Lesson 6 Activity on multiplying with base-tens.
In this lesson, we will learn the Partial Products method of multiplying multi-digit numbers.
In this video we will review the Lesson 7 Activity for partial products.
In this lesson, we will continue working on the Partial Products method of multiplication. We will work on more complicated problems using this method to get more practice and increase proficiency.
In this video, we will review the Lesson 8 Activity for Partial Products, multiplying two and three digit numbers.
In this video, we use a tile activity to practice Partial Quotients.
In this lesson, we will learn to use the area model to multiply multi-digit numbers. We will discuss the similarities of the area model to the partial products method.
In this video, we will review the Lesson 9 Activity for the Area Model of multiplication.
In this lesson, we will learn the traditional method of multiplication. This is the most common method of multiplication, and one that most adults are most familiar with.
In this video, we will review the Lesson 10 Activity for the Traditional Method of Multiplication.
In this lesson, you will learn the last of our multiplication methods--lattice multiplication.
In this video, we will review the Lesson 11 Activity for lattice multiplication.
In this video, we will review Lesson 11: Activity 2. We will review all four methods for each problem so that you can see the problems solved with your choice of methods.
In this lesson, we will review several key multiplication contexts. We will practice multiplication word problems and discuss a procedure for approaching them.
In this video, we will review the Lesson 12 Activity focusing on multiplication word problems.
