What is number sense?
In her book, About Teaching Mathematics, Marilyn Burns defines it this way:
Number sense. [Children have number sense when they] can think and reason flexibly with numbers, use numbers to solve problems, spot unreasonable answers, understand how numbers can be taken apart and put together in different ways, see connections among operations, figure mentally, and make reasonable estimates.
This week’s activity helps children think about numbers as they relate to each other. By asking themselves questions about numbers, children will also learn to think about whether answers are reasonable or unreasonable.
For example – would it be reasonable to own ten pencils? Would it be reasonable to have ten flowers? How about ten cars?
This game was designed with first graders in mind, but you could play it with preschoolers and kindergartners if they can identify numbers 1-100.
To play, I brought out my preschooler’s plastic hundreds board (which we LOVE!) and the free printable materials found at the end of this post.
To play:
- Print out the hundreds chart, Yes & No mat, question cards, and picture cards found in the download. Cut apart the cards.
- Take turns rolling a die.
- When you roll the die, refer to the question cards to find out which question to ask.
- Draw a picture card. Locate the number on the 100s chart. You can cover it, color it, or just point to it.
- Ask yourself the question in relation to the card. For example:
Do you want 6 mittens?
Could a person have 22 socks?
Do you have 100 crayons?
5. After you decide on a “yes” or “no” answer, place your card on the proper section of the Yes & No mat.
As you can see, this isn’t a competitive game. It’s just a fun way to think about numbers! And because you draw different cards depending on what number you roll, it can be a different game each time you play.
Here’s how the game looks in action:
My first grader rolled a four. He looked up at the question cards. When you roll a four, you ask yourself, “Do you want this many?” He drew a picture card. It said, “16 bathrooms.” He located 16 on the hundreds chart and covered it. Then, looking at the picture card, my son asked himself, “Do I want 16 bathrooms?”
His answer was a definite no. “Because then I’d have to clean them all!” Good answer. 🙂
He placed the picture car on the “No” section of the Yes & No mat.
Sometimes we weren’t sure about the answer. Could a person have 49 pairs of scissors? Maybe an art teacher would, so we said “Yes.”
Do you want to have 99 books? “Yes!” my first grader exclaimed.
Is it possible to have 44 baby brothers? Probably not. 🙂
We hope you enjoy building number sense with this activity!

I cannot thank you enough for all of these fun, free resources. I am an elementary level special educator and use these to work with my small groups. Thanks again. You are amazing!
Anna Geiger
Thank you so much, Lynn!!

I’m going to use this game in my co-op class this coming week. It looks great and very engaging! Thanks for providing these resources for me.
Anna Geiger
I hope the students enjoy it, Shonda! We had fun with this one.

OMG I love this! Sooo much fun! I’m going to use this with my EFL kids to practice their numbers and do some speaking as well! Fun! Fun!
There’s only one thing though, with one set I won’t have enough, so would have to make either one for each, which could get expensive (laminating, etc) or I could use a couple of sets and have them work as teams, but that would depend on a couple of of circumstances.
How long does this activity tend to last?
Is there a chance of you creating more cards? That would be soooo cool!
Thanks so much for such an awesome activity!
Anna Geiger
Hello, Carolyn!
This activity can last as long as you’d like it to – I would guess about 15 minutes if kids locate each number on the chart and do all the cards.
As far as printables go, this one is pretty low cost, as it’s in black and white… and you could just print on cardstock and not laminate if you’d like.
Unfortunately I don’t have time to make more cards. 🙂 It’s a pretty big set, though!
Carolyn
Thanks for replying Anna!
Yeah, you’re right. I realized that after posting. If the kids go through it well it should last those 15 mins or so, but the moment they have troubles with the numbers it will take them longer – some numbers are pretty hard to say in english for these kids!
I laminate everything! hahaha I need it to last forever but more important, I want to be able to clean them every so often if any sticky fingers (or worse) get to them. (A nice wipe down with alcohol for a quickie desinfection)
Thanks so much!

This is such a fun resource! From one busy mama to another …. THANK YOU 🙂

You’re very welcome, Steph! 🙂
