How to use these cards in a number talk setting:

•Show students a card for 1-3 seconds (depending on card). Some teachers call this a “quick look.” Don’t show it for so long that students can count the objects. The idea here is to use multiplicative reasoning to figure out the number of objects.

•Ask students to raise a hand (or a thumb to chest as you might do with number talks) when they know how many objects are on the card. Allow enough thinking time for all students.

•Ask students to share.

•Show the card once again (leave it up this time) and talk about the answers/strategies that were shared.

•Encourage students to move from additive reasoning to multiplicative reasoning.

I've included FOUR different styles of subitizing cards:

- Rekenreks

- Ten Frames

- Dot Patterns inside Ten Frames

- Dice Patterns

For each style, representations are included for facts up to 10x10.

These are intended for printing rather than displaying on a screen. I've used some half pages and some full pages to make printing more efficient.

⭐️⭐️⭐️⭐️⭐️ "We are currently doing a book study with Math Fact Fluency by Jenny Bay-Williams. We used this resource in addition to her book. Great resource!" Victoria W.

⭐️⭐️⭐️⭐️⭐️ "My students love it when I bring these cards out. For them it means number talk time and for me a great resource that I have used all year (even in distance learning)." Laura H.

⭐️⭐️⭐️⭐️⭐️ "This is a great resource to help build number sense. I love that there are multiple representations - especially the rekenreks - because I think that deepens students' understanding." Kathleen V.
