Multiplication Tricks & Help with Math Homework

Multiplication Tricks & Help with Math Homework

Multiplication tricks can significantly help your child when multiplying two-digit numbers by three-digit numbers.  This article will show you and your child how to utilize these tricks, and offer your child some help with math homework.  The first trick is skip counting.  Most teachers instruct their students how to skip count ( 5, 10, 15,20…), but few teachers instruct their students how to integrate skip counting with the multiplication algorithm.  This article will offer help with math homework by giving video tutorials that demonstrate how to integrate skip counting with the multiplication algorithm.

The second trick is call “Area Multiplication”.   I designed Area Multiplication specifically for my 6th grade students who were struggling with the conventional method of multiplication.  Area Multiplication uses an area box, which is an easy way of keeping each number in the correct place value position.  I have had incredible results with Area Multiplication!  These strategies work with children who have ADHD, Dyslexia, and other learning disabilities.  Virtually every one of my students who has learned these multiplication tricks has passed the standards based assessment for multiplying double digit numbers.

This post is part of a series designed to offer help with math homework, so that ANYONE can successfully multiply large numbers.  The first book, (Area Multiplication: Book 1) teaches how to multiply a two digit number by another two digit number, as in 86 x 97.  This is the second book, (Area Multiplication: Book 2).  It teaches how to multiply a two digit number by a three digit number, as in 94 x 368.  The third book, (Area Multiplication: Book 3) teaches how to multiply a two digit number by a four digit number, as in 37  x 6,375.  The fourth book (Area Multiplication: Book 4) teaches how to multiply a three digit number by a four digit number, as in  694  x 6,368.  And, the fifth book, (Area Multiplication: Book 5) teaches how to multiply with decimals.

Does your child struggle with multiplying large numbers, because he or she does not know all their multiplication facts?

The problem below is called a “Watch Me” challenge.  This Watch Me challenge introduces the strategies of skip counting and Area Multiplication.  More importantly, the video demonstrates how to use these two strategies while solving a multiplication problems.  I encourage you to watch this first video with your children and to discuss the strategies.  Then have your child write this first problem in their math notebook.

Could your child benefit from a little One-On-One tutoring?

The problem below is called a “Work with Me” challenge.  This challenge encourages your child to work step-by-step along side me to solve this challenge.  All of the following challenges are called “On Your Own” challenges.  However, many of my students who struggle with multiplication will do five or six of the “On Your Own” challenges as a “Work with Me” challenge.  They play the video, pause it, and copy the strategies until they feel comfortable and confident.  Doing the problems as a “Work with Me” challenge is like having a personal tutor.
