Tuning in to Multiples on Tuesday
Who would have thought that we'd be exploring multiplication today? Here's how we got there ... it all started with a question: What is special about the number 9? You were full of ideas, not surprising given that you are all brilliant thinkers. I asked you to tap into your background knowledge about all the connections you could make to the number 9. Here are some connections:
"It is the largest single digit before you go to the double digits."
"911"
"You can be nine years old"
"it is on a scale"
"it is on license plates"
"September is the 9th month."
"it is made up of multiples of 3."
We then started to notice the connections between 9 and 6. They are both made up of multiples of 3 and this is when it started to get good ... we began to see that 3+3 = 6 and that 3 + 3 + 3 = 9 AHHH the magic of 3.
This prompted us to start experimenting with arrays. An array is an arrangement of quantities or symbols in rows and columns. Here is a video for you to watch if you want to learn more about creating arrays to understand multiplication. https://www.youtube.com/watch?v=3rQRn-7uGaE
Did you know that arrays are everywhere in the world. Just pay attention on purpose and see what you can find. Here's a link to videos with examples. https://www.youtube.com/watch?v=ks-q6gKoQKs
Here are some photos of the arrays you made on white boards:
Skip counting is really important for multiplication because we are using repeated addition to work with numbers in groups. Here is an introduction to multiplication video to check out: https://www.khanacademy.org/math/cc-third-grade-math/cc-3rd-mult-div-topic/cc-3rd-mult/v/multiplication-intro
