Adult Introduction to Laws of Multiplication Series

This is an introduction for the adult to be able to understand and prepare for the lessons of the Laws of Multiplication as well as other lessons in math . This video explains the materials needed to have success with these lessons.
Laws of Multiplication #1 - Commutative Law of Multiplication
13:57

Laws of Multiplication #1 - Commutative Law of Multiplication

This lesson introduces the concept and the terminology of the Commutative Law of Multiplication. The lessons begins with the Montessori bead material and progresses into working on paper.
Laws of Multiplication #2 - The Distributive Law of Multiplication
10:26

Laws of Multiplication #2 - The Distributive Law of Multiplication

The second lesson in as series on the properties or laws of multiplication. This lesson is designed for ages 6 to 8, but is an important indirect preparation for algebra.
Laws of Multiplication #3 - Applying the Commutative and Distributive Law
12:32

Laws of Multiplication #3 - Applying the Commutative and Distributive Law

This lesson combines the commutative and distributive laws of multiplication using the color beads and gray multiplier cards. This lesson is for 6 to 8 year-olds, but it is also an indirect preparation for algebra.
Laws of Multiplication #4
11:50

Laws of Multiplication #4

This is the fourth lesson on the Laws or Properties of Multiplication. In this lesson we have two numbers times two numbers. This shows the distributive property with two multipliers and two multiplicands and then we apply the Commutative property as well.
Laws of Multiplication #5
14:21

Laws of Multiplication #5

The fifth lesson in the Laws of Multiplication continues the journey from the hands-on manipulative material to the first steps in representing the quantities through numerals. This step is an important move towards eventually recording these equations on paper only.
Laws of Multiplication #6
11:14

Laws of Multiplication #6

Laws of Multiplication #7 Cards Only
13:51

Laws of Multiplication #7 Cards Only

Laws of Multiplication #8 - On Paper Only
09:29

Laws of Multiplication #8 - On Paper Only

This lesson completes the first series of the Laws of Multiplication. The student is now using a notebook to record their work and the materials are not needed at this point. The next lessons will involve multi-digit multipliers and multiplicands.
Laws of Multiplication #9 - Multi-digit X Multi-digit
09:39

Laws of Multiplication #9 - Multi-digit X Multi-digit

This lesson introduces a the multiplication of a two-digit number times another two-digit number. It introduces treating a two-digit number as a binomial. Thus in this lesson we are multiplying a binomial times a binomial. It is a great mathematical and sensorial example of an algebraic binomial multiplication.

Laws or Properties of Multiplication

Multiples of Numbers #1 and #2
15:02

Multiples of Numbers #1 and #2

This is an introduction to the concept of multiples of numbers. We use the short bead chains and colored bead bars to present this concept. I have included some optional homemade materials as well.
Multiples of Numbers #3: Multiples on Paper
13:46

Multiples of Numbers #3: Multiples on Paper

This video is the second in a series on Multiples of Numbers. In this lesson we cover the transition from the colored beads to recording multiples on paper.
Multiples of Numbers #4: Common Multiples
08:07

Multiples of Numbers #4: Common Multiples

This lesson introduces finding common multiples of two or more numbers and plotting the multiples on the "Multiples of Numbers" paper.
Multiples of Number #5: Common Multiples #2
09:35

Multiples of Number #5: Common Multiples #2

This lesson looks at common multiples again using the Multiples of Numbers paper. It also introduces taking a given number and finding all the numbers that it is a multiple of.
Multiples of Numbers #6 - Table A
12:44

Multiples of Numbers #6 - Table A

Table A & B list the multiples of 2 through 10 up to a product of 100. These two sheets of multiples are often repeated many times during the elementary years and serve as a reference for later work in factors using Table C.
Multiples of Numbers #7 - Table B
09:35

Multiples of Numbers #7 - Table B

Table B lists the multiples of numbers between 51 and 100. This is a lesson that can be viewed right after Table A as they both are part of the larger picture of recording all the multiples of the numbers from 2 to 10 up to 100.
Marshall Math - Unit 1 - Intervals
20:04

Marshall Math - Unit 1 - Intervals

This is the first chapter in the Kim Marshall Math Series. This chapter introduces intervals in a series of numbers. These intervals are lists of multiples. This work usually begins in 4th or 5th grade. It is best to go through the chapters in order.
Factors # 1 Introduction - Table C
17:07

Factors # 1 Introduction - Table C

Table C is the student's first introduction to the concept of factors. This two page chart allows the child to plot all the factors of numbers up to 100 using the multiples Tables A and B.
Factors #2 - Prime Numbers - Table C
07:37

Factors #2 - Prime Numbers - Table C

The concept of prime numbers is introduced using Table C and then transferring the prime numbers to the Multiples of Numbers paper. This is the first introduction to the concept of prime numbers and it follows closely after the the presentation of Table C.
Marshall Math Unit 3 - Factors and Prime Numbers
05:32

Marshall Math Unit 3 - Factors and Prime Numbers

Chapter 3 covers factors and prime numbers of numbers 2 to 50. It is a great follow-up practice to tables A, B, and C.
Factors Using Pegs or Objects
11:15

Factors Using Pegs or Objects

Discovering the factors of a number is presented using the traditional Montessori Pegboard, but it can also easily be experienced with other objects like coins or counters. This lesson can be done with younger students with great success. Older students benefit from the clear manipulative visualization of the concept of factors.
Finding Common Factors
10:32

Finding Common Factors

Finding the common factors is an important ability that will help as a student works with adding and subtracting common fractions by being able to find the Greatest Common Denominator of two or more fractions.
Lowest Common Multiple
13:54

Lowest Common Multiple

This lesson shows how you can find the Lowest Common Multiple of two or more numbers using counters and paper. This is an important skill for later work with adding and subtracting fractions.
Prime Factors
14:06

Prime Factors

This lesson shows how to find the prime factors of numbers up to 100.
Prime Factors on Paper
07:14

Prime Factors on Paper

This lesson provides the step from working with the pegboard or counters to recording prime factors on paper only. The lesson presents the "T" method that represents the pegboard and also the classic "root" method.
Marshall Math Unit 4 - Prime Factors
08:39

Marshall Math Unit 4 - Prime Factors

Exploring Prime Factors using the traditional bubble or "root" method as demonstrated in Unit 4 of the Marshall Math Series Book A.

LESSONS CONNECTED TO THE KIM MARSHALL MATH SERIES - BOOK A

This series of lessons follows the order of the chapters in the Kim Marshall Math Series - Book A - Each of my video lessons connects a chapter of the book with at least one Montessori math lesson. These lessons are best for Upper Elementary age students (4th-5th grade). Following the chapters in order will prepare the student for the review pages in each chapter.
