# The Animated Multiplication Table

I made multiplication table using * PowerPoint* and went on to discover some very interesting relationships within the table.

You will see several here. Watch the video below.

I love all of your materials! I am the instructional Math Coach and I use and share your materials with students and teachers in all grade levels at my school! I used the animated multiplication table recently and it has now stopped working! I tried to download again as a different file, but am not sure what has happened. I wasn’t sure if it was something behind the scenes or if there was a google slides available.

Any advice?

Hi, Amanda. Thank you for letting me know. There isn’t a google slides version available since slides doesn’t support that animation. What version of PPT are you opening the table with?

Hi Amanda, I’ve been a big fan of Steve’s work too, and created an Animated Multiplication Table that works in a browser, so you aren’t constrained by Powerpoint. Here’s the link! http://www.scienceoftech.net/ZZ/AnimatedMultiplicationTable.php. Best, Scott

Thanks for sharing this, Scott!

Thank you so much for sharing these wonderful resources online. My daughter is 6 and we we’ve been using Splat. I normally work on one thing a week and was ready to move on but she wants to carry on playing. It is really helping a lot to see number bonds and to have an idea of maths beyond the worksheet and the usual notation. I find it very helpful. We will be exploring estimation thanks to you too! This is math appreciation for the whole family.

Warmest greetings from Allariz, Spain.

Thank you for this note, Laura! Wishing you all my best!

Steve, it is obvious that you love what you do and it is amazing that you are willing to share to make an impact on today’s conceptual learners. Thank you for making this journey even more exciting!

Thanks>> My kids are all about this new strategies to do math. Much more fun than what I grew up with.

Thats just awesome and thank you for sharing this…

Thank you!

I have seen many websites with multiplication tables like this one http://math.tools/table/multiplication . First time I came across one using powerpoint. Looks nice and can be referenced while offline too. There are couple of patterns that I haven’t noticed before and you pointed out that in the video. Good post.

Hi, Sam. Thanks for sharing out these links and resources. I’m glad there are so many good resources available. I’ll keep adding to the blog as I go. I have a few more posts nearing completion. I hope you will enjoy them!

Thank you!

And using it resulted in one of my best math lessons.

I asked kids if they thought there were more odd or even numbers, and then we checked and discussed.

Then we did lots of “what do you notice?” stuff. For example, somebody asked the question about what it might look (after we’d marked all the even numbers) if we then marked all the odd numbers too. There were lots of theories. Then the big reveal…

Thanks for the great chart!

I love this and have used it with students in the past. Unfortunately this year my school replaced my computer with one that only has google tools, so I can’t use this. By any chance, have you got a version that works without powerpoint or excel (or whatever it is. Maybe Google Slides? I

Hi, Julie. I’ve checked into how to make this work with google slides, and I’ve been told that it won’t work with google slides – only with PPT. However, there may be a solution. Try downloading the free PPT viewer. That may be all that you need. It won’t allow you to create your own slides, but should let you play any slides written in PPT. Please let me know if this solution works. Here is a link. https://www.microsoft.com/en-us/download/details.aspx?id=13

My note below shows how you can use an online version of the powerpoint file in an interactive HTML format. http://www.scienceoftech.net/HundredsChart

If you have any requests for modifying the code to meet your instructional needs, please contact me at scox at umasd.org

Thank You!

Fascinating! This reminds me of the arrow in FEDX Logo It has always there, we just never took a second look for details. The equivalent fractions on the timetable chart…Amazing! I’ve used this chart for practically a Century and never thought for one second to explore or discover multiple observations nor additional ways to use it to solve math problems.

Thanks a million!!! you have opened my mind to a whole new dimension of observing the world around me on a daily basis. Equally important, you have refreshed, rejuvenated, and sparked a fresh and exciting new outlook as I plan, then engage students in all my lessons, especially Math. Thank You Thank You!

Ann, thank you for this very thoughtful comment. The more I look at the chart the more I see within it. The animated multiplication table has given me a way to see it differently and that has opened my eyes as well. Let’s keep sharing out what we discover because it is so important. I really appreciate the time you have taken to share your experience with me.

This a wonderful tool. I’ve used old-fashioned paper charts and colored pencils, but this is much better! Thanks for creating and sharing.

You are very welcome. I a glad that it will be a helpful learning resource for your students!

I love these patterns! It’s great to make them visual and spark some interest by making it possible for students to discover some new patterns and then wonder why they work.

I’ve written about a few other multiplication table patterns, more aimed toward the high school level. The ideas are summarized in the form of questions in the Julia Robinson Math Festival (http://jrmf.org) activity that is linked in my blog at https://uncoverafew.wordpress.com/2015/02/05/multiplication-table-part-1/

Joshua, thank you for commenting and also for sharing further resources. I’m blogging to learn, and I love that I’ve just learned some more. Thanks!

I was fascinated by the idea of choosing 2 adjacent columns and 2 adjacent rows. A 2 x 2 square is formed at the intersection. If you multiply the numbers in each diagonal of the square, the products are 1 apart. Of course, this made me want to figure out why. Here is my “proof”:

h h+ 1 6 7

v vh v(h+1) 4 24 28

v+ 1 (v+1)h (v+1)(h+1) 5 30 35

top left to bottom right diagonal sum (let v = 4 and h = 6)

vh + (v+1)(h+1) (4)(6) + (4+1)(6+1)

vh + (vh + v + h + 1) (4)(6) + [(4)(6) + 4 + 6 + 1]

2 vh + h + v + 1 2[(4)(6)] + 4 + 6 + 1

bottom left to top right diagonal sum

[(v + 1) h] + [v (h + 1)] [(4 + 1)6] + [4(6+1)]

vh + h + vh + v [(4)(6) + 6] + [(4)(6) + 4]

2 vh+ h + v 2[(4)(6)] + 6 + 4

On the hundreds chart, when two adjacent numbers on the vertical axis are multiplied by two adjacent numbers on the horizontal axis, the top left to bottom right sum will always be 1 more than the bottom left to top right sum.

Elaine,

Wow! I am impressed! This also deeply fascinated me. Your work here is really impressive! Nice going! Wow!

Just wanted to offer this to anyone intrigued by Steve’s idea: I coded a page that will duplicate the Powerpoint file, and hosted it here: http://www.scienceoftech.net/HundredsChart

Since it lives online, there is no need to download anything or install a plug-in. Hope it finds a place in your teaching plans….

This is a great resource that I will share with my elementary school and middle school math-teaching colleague in my district…thanks, Steve!

Excellent! I hope it will be a very useful resource for many students and teachers!

Steve,

Very nice table! I love the opportunity that this tool offers for students to visualize relationships. I was curious – the last relationship you mentioned you said pick *any* three numbers (rows) and then one number (column), and the first two products sum to the third. This would only be true if the first two number rows selected (2 and 5 in your example) sum to the third row selected (7 in your example). This would fail if say you picked rows 2, 4, and 9, and column 5, as the products 10 and 20 do not sum to 45. However, as long as the first two rows selected do indeed sum to the third, then the relationship would hold and is a nice example of the distributive property, among other things.

Keep up the great work!

Brad

Brad, this is a great comment! Nice catch. I agree with you. Now, I’d like to go back into the recording and insert a few more words to address that. I also notice that if the rows were 1, 2, and 3 that the numbers would sum to the corresponding number in row 6. Also, if the numbers were from rows 1, 2, 3, and 4, they would sum to the number in row 10. I think there is also an interesting proportional relationship, but you’ll have to confirm this. I think that the sum of the numbers in rows (say) 3 and 5 would also be 8/7 times greater than the number in row 7. I think any other such proportional relationship would hold true. What do you think?

Steve,

The pattern you are describing deals with triangular numbers. The sum of the first n consecutive positive integers is (n(n+1))/2. So the sum of the first four positive integers should be (4(4+1))/2 = (4*5)/2 = 20/2 = 10, and 1+2+3+4 indeed equals 10. This pattern is evident in Pascal’s Triangle, and I’m sure that other commonalities between Pascal’s Triangle and the multiplication table might emerge – I wonder what relationships and patterns others may find!

Very clever! thanks for sharing! I can’t wait to show this to my students!

Great! I’d love to hear how it goes, Terri!

That animated chart is so cool! Thanks for sharing!

You’re welcome, Mark! Thanks for leaving a note.

Great share.

One comment. Towards the end (at 1:57), when you say “take any 3 numbers” and choose 2, 5, and 7, your observation only works because 2+5=7. The numbers in dark red cells won’t add like you show if you chose 2, 5, and 8, for example.

That is a great point. I just read a similar note and replied to it. Thank you for mentioning that. I agree that it might point toward a different kind of relationship, which really interests me, and I never would have thought to investigate it without a comment such as this. That’s a great catch. I mentioned in the earlier post that I’d like to go back into the recording and insert a clarification there, but I’m glad I’m learning. Have a great day!

You might like the ideas suggested here: http://www.cut-the-knot.org/blue/SysTable.shtml

The point he makes is one, I think, you are suggesting implicitly: while most teachers think memorization and drill when they hear “multiplication table,” there is actually a lot of interesting mathematics (patterns, hypotheses, exploration) lurking there.

Also, as previous commenters have suggested, would be great to have a copy of your powerpoint table.

Hi, Joshua. I’ve added a link onto the post so the chart can be directly downloaded now. Enjoy!

Great, Steve! I too would like to use this. Could you send me a copy?

Simon, I’ve added a link to the post so that the chart can be downloaded.

Great PowerPoint! Can you tell me how you made the shading appear with a click?

Hi, Liza. I’ve added a link so that the chart can be downloaded. About the shading appearing, try dabbling with animation triggers. Click on one thing to make another object appear. Perhaps an easier way to think of it is to set the animation you want, but then to go in and set the trigger on that animation to another object. So, when you click on X, Y goes into motion.

Just as awesome as the Hundreds chart! Love it!

Thanks, Jen! I appreciate your helping me on my way on this journey!

This is really interesting – thanks. I will try out some of these ideas at school – although I’m not sure I can make a table like this!!

Hi, Lizzie. There is a download link on the blog post now.

I would LOVE to use this with my students! Would you be willing to share an electronic copy of your PowerPoint?

Christi, I’ve added a download link so you can copy the chart out of the blog now. Enjoy!
