1 Number Talks Visualizing the Math Using Dot Images Grades 2 - 5
Laura Stokes Elementary Resource Teacher Columbus Regional Mathematics Collaborative The intended use of this presentation is for the facilitation of classroom mathematics discussions in the upper elementary grades and not for distribution among wider audiences. It is for non-profit educational purposes."

2 These dot image slides are set up so that each image is visible 3 individual times for 3 seconds each time. From the “How many dots do you see?” slide, click and the first image will appear. After the 3rd time, the screen will be blank for you to write down the number of dots students report. Then click again and the image will show up in the lower left corner to allow students to view while they are describing the strategies they used to determine the number of dots. Slides are set up in a loose progression of difficulty. Select slides that best fit your students and the strategies you are addressing. Last three slides of this file are: the intro slide for each dot image, a 4 x 5 dot array, and a 6 x 8 dot array. The two arrays are individual dots. Delete dots and create a pattern, click drag over the remaining dots – highlighting them all. Finally, right click “group” and you have made your own dot image!
