This week's content is provided by Pierre Tranchemontagne, an educator who has provided us with a fantastic resource for you to use with your child(ren). If you have not yet checked out his work, do it now! From Pierre: How many dots? How do you see them? This image can be found on Number Talk Images- a website dedicated to collecting interesting images that spark "math-y" conversations. The questions above are a great way to start this conversation with children. There is obviously a fixed amount of dots in the image above; however, there are multiple ways of seeing them. Did you see the dots organized vertically from left to right as 2-3-3-2? Did you see 2 groups of 5 horizontally or vertically? How about groups of 3 dots from bottom left to top right with one left over? What about 3 groups of 4, minus 2 dots that were counted twice? Another way? It is always fascinating to find out how other people “see” the image. Here are a few more images from the website: Using these types of images to prompt a Number Talk are a great way to spend time with children developing number sense concepts such as subitizing (recognizing small groups of items within the larger group), unitizing (treating a group of 4 objects, for example, as 1 unit), flexibility with computational strategies, efficiency and number facts, among others.
Here are some tips on using Number Talk Images at home:
Lastly, I am always interested in hearing about conversations prompted by an image from the website. How did it go? What did your child find interesting? What did you find interesting? Please share your experiences by sending them to pierre.tranche@gmail.com How are you using images to have Number Talks at home? Comment below or find me on Twitter at @tabletalkmath to continue the conversation.
