Here is a peak inside one of my favorite boxes
and binder rings
. I use these to create subitizing cards and other projects with K-2 kids. Today I want to show you 2 of the things I have been working on with these materials with a group of first graders.
Subitizing Cards
Subitizing is the ability to recognize a quantity without counting. It is further broken into perceptual subitizing and conceptual subitizing. Need more information on these words? Check this out!

| I use the dot stickers and cards to work with students to create different arrangements and combinations of a given number. You can see on this day we were working on combinations of 6. See how the different arrangements and color patterns lead you to see 6 in different ways? This is a great example of conceptual subitizing and is a great way to work on combinations of numbers. The hole punch in the top lets me put these on a binder ring and then we use them in class and small groups. We flash a card at a group of kids and they tell how many they saw and how they figured it out. |
Double Flap Cards
I actually made these this week in first grade and with some intervention second graders. These are a great way to work on combinations of numbers and fact families. The particular kids I had that day were really needing more work on combinations of 10 so we made double flap cards for 10. I used the same stickers and a few sheets of card stock

| This is what is written on the back of each double-flap card |
 |
| Here is the 3+7 card with both flaps open. We can use this card to generate all the facts in the fact family for 3+7=10 |
 |
| I might open one flap and ask kids how many they see. I then might ask them how many are under the other flap. |
 |
| I vary my language a bit and ask other questions such as, "how many do we need to add to 6 to get to 10?" I also might open both flaps and ask what will be left if I cover up the 10 (or take the 6 away etc) |
