Welcome to the Give-a-Number Game!
This page will walk you and your child through the Give-a-Number Game, which scientists (and now you!) can use to find out what your child knows about numbers.
After you complete the game, you will receive personalized information about your child's current number knowledge and research-based suggestions for how to support their learning.
The game will take about 5-10 minutes to play with your child.
You will need:
- A 2-5 year old child
- A phone, tablet, or computer with internet access to follow along with these instructions
- About 10-15 small toys of a similar type (e.g., plastic fish, blocks)
- A plate or other shallow container that your child can place the toys into
Example materials:

This project is run through the Conceptual Development Lab at foundry10, an education research organization based in Seattle. If you have any questions, feel free to reach out to the lab's Principal Investigator, Dominic Gibson (dominic@foundry10.org).
Confidentiality: No identifying information regarding individual children will be stored. Anonymized data collected through this game will be accessible to foundry10 researchers and may be shared with the wider research community.
