With a click, a pattern of dots appears on your screen. Instantly your students tell how many. They don’t count the dots. Instead they simply know the total at a glance.

Subitizing – when a person looks at a small set of objects and instantly detects the total without counting. It’s a powerful process and a truly remarkable one.

I have a new resource for you. 100 Subitizing Slides & 10 Challenge Patterns.

There are 10 sets, and each set includes 10 subitizing slides and 1 challenge pattern. In between each slide, I’ve placed a blank slide. As you click through the slides the effect will be that the slides are appearing and disappearing – at the rate that you choose. The blank slide will also allow you to toggle back and forth to an image or simply move forward to the next image.

Then, after 10 quick subitizing experiences, you’ll see one challenge image which will be duplicated several times on the screen.

Download the sets, try it out in your classroom, and let me know how it goes!
