I remember watching my 3-year-old niece, Avi, try to organize her toy cars. She wasn’t counting them yet, but she would say, “This one goes near the red one,” and “I want more cars here!” At the time, I just thought she was talking as she was playing. I didn’t realize that in those moments, Avi was actually building the foundation for her entire mathematical future.
We often think of early math as just learning to count from one to 10 or recognizing numbers and shapes. However, recent research suggests that the words we use to describe relationships and quantities, what experts call mathematical language, might be a critical factor in a child’s early numeracy success.
The Secret Ingredient for Math Success
A study involving children aged 3 to 5 discovered that while general vocabulary is helpful, mathematical language is a much stronger predictor of how well a child will perform in math. Interestingly, when researchers looked at both general language skills and math-specific words, they found that mathematical language was the unique factor that predicted a child’s numeracy performance.
This means that even if a child has a great general vocabulary, they might still struggle with math if they haven’t mastered specific “math words.” These words act as tools that help children refine their understanding of exact quantities and spatial relationships.
What Exactly is Mathematical Language?
These are the two main categories of mathematical language that you can start using at home today:
- Quantitative Language: These words help children make comparisons between groups, such as “more,” “less,” “fewer,” “fewest,” “most,” “same,” and “different.
- Spatial Language: These words describe where things are in relation to each other, like “before,” “after,” “above,” “below,” “nearest,” and “far away.”
When a child understands these terms, they aren’t just memorizing words; they are learning to do math by describing the world around them.
It’s Never Too Early to Start
One of the most encouraging findings is that mathematical language is malleable, meaning it is a skill that can be intentionally taught and improved through daily interactions. In a recent study, researchers taught preschoolers with developmental delays to compare and contrast common everyday items to boost their understanding of “same” vs. “different.”
How to Boost Math Talk in Your Home Today
You don’t need sophisticated equipment to help your child. You just need to bring math into your daily conversations.
- During snack time: Compare who has more crackers, whose pizza has no pepperoni.
- While cleaning up: Race to find the toys nearest the door. Find all the bigger blocks.
- When reading together: Use storybooks to point out who is first in line or which character has the fewest strawberries.
By making these small shifts in how we speak, we provide our children with the linguistic toolkit they need to succeed in school and beyond.
