Subitizing is the ability to quickly identify the number in a group of objects without individually counting the objects. Subitizing is a concrete way to explore composing and decomposing numbers. Students will see dot patterns in different ways, and that is a great thing. When showing students 16, made from a square students might see 4 groups of 4 or two 10 frames with each 10 frame missing 2.
There are 30 prompt cards included in this resource that offer 3 weeks of powerful number conversations. These conversations and prompts are simple ways to build fluency within 20, as well as, allow students to explore how numbers can be composed and decomposed in many different ways.
Can be purchased in a discounted, year-long 2nd Grade Talking Numbers Bundle HERE.
Purchasing This Resource Gives You Access to…
This is a digital file. May I print it?
While intended to be a digital resource, it can also be printed. To do so, go to File > Print > Lay Out > Pages Per Sheet > 2 or 4 > Print. 2 to a page prints with awkward margins but are easier to read and write directly on. 4 to a page prints in perfect task-card form (the size of post cards).
How Do I Use These for a Whole-Class Number Talk?
Using Google Slides you are able to display these prompts. If you download the Page Marker Google Chrome extension, you can write directly on the slides (no log-in required) in different colors. Using an Interactive Whiteboard, you can use the markers or your finger to write on top of these images/slides. If using a touch-screen Chromebook or iPad, you can use a stylus to record students’ thinking. Should you want to rock a low-technology option, display the prompt on a screen and record student thinking on anchor chart paper, a white board, or an easel.
Can I share this with students?
Yes! On a password-protected site or platform, you are welcome to share this digital file with students and families. That might look like a Google Classroom, a password-protected website, a password-protected Flip Grid, See Saw, etc. Due to copyright, the digital file may not be placed on a class website that is accessible to the general public. Have questions? Ask a Q&A on Teachers Pay Teachers, and I’m happy to answer!
With what programs is this compatible?
This digital file is able to work with GoogleTM Slides, Google Drive, SeeSaw. Microsoft OneDriveTM, or Pic Collage. Note – In SeeSaw, the interactive pieces do not work. Then students may submit their thinking digitally. For instructions on how to use this resource with Microsoft OneDriveTM and SeeSaw visit bit.ly/digitalinstructions
Can I share just one or a few prompts at a time?
After you make a copy of this digital file and add it to your Google Drive, you are free to manipulate the slides. You can add/delete/or move around the pages to meet the needs of your students. Only want to share one prompt? Perfect. Delete the other slides and share the file via Google Classroom for your students. Then, when you want the rest of the tasks, you can come back to this link and reopen the original file.
Happy Teaching,
