Multiplication and division lessons - grades 3-4

I have been working in a particular section of my HomeschoolMath.net site - the section that has free math lessons. It's been needing some updating for a long time... and finally I got around to it. Websites are like most anything else you own - you have to take care of them. Well, they CAN go on their own (like autopilot) for a while but if you never update them, they will eventually lose traffic and go downhill. I still have lots of work to do... (and I'll do my best to keep cleaning and improving the pages in this section) but here are some updated multiplication and division lessons. They are essentially sample lessons from my books. Enjoy! Multiplication Lessons Grade 3 Multiplication concept as repeated addition Multiplication on a number line Multiplication is commutative Multiply by zero Multiplication word problems Order of operations Grade 4 Multiplying by whole tens & hundreds Distributive property Partial products - the easy way Multiplication...

How to teach long division

Long division is a hurdle to many students. I have written a long article about it where I approach teaching long division in several small steps. It is all also explained in this video: The video and the article do not delve into the "why" long division works, but suggest a specific sequence of teaching long division. It should also make the process of finding the remainder within long division more transparent to students. Please read my article from this link: How to teach long division I've also created a page with lots of worksheets for long division plus a generator so you can even customize them to your liking. What about teaching why long division works? I feel the algorithm of long division AND why it works presents quite a complex thing for students to learn, so in this case I don't see a problem with first learning the algorithmic steps (the "how"), and later delving into the "why". Trying to do both simultaneously may pr...

Long division and dyslexia

Photo by laura.bell I have a dyslexic 9 year old and I wish to find out if your program can benefit him. I have tried Math-U-See and it became too boring or frustrating for him. I have tried various other programs in hope of not overwhelming him. He has completed the delta Math U See level but I feel needs more work on long division. He simply gets very frustrated with it, as the length of time and knowing where to place number due to dyslexia. Is your curriculum a spiral curriculum? Any suggestions would help. One of my books from the Blue Series goes through long division in several small steps: Math Mammoth Division 2 I would suggest that for a dyslexic child, have him do ALL the problems on a squared paper (grid paper). That will help him place the numbers right. Not all the problems in my division book are done with the grid... but for your son, it may be necessary to always use such paper. Secondly, when you teach on board or on paper, at each step COLOR the wh...
