Yesterday, we went out for lunch to celebrate Mother’s Day, and like any math-loving parent, I noticed an opportunity to teach my kids something new! Our table number was 40, and I turned it into a quick, fun math lesson.
Quick Number Exploration with 40
I asked my 14- and 10-year-old these questions about the number 40:
Is 40 a prime number?
What are the factors of 40?
Is 40 a square number?
What is the square number smaller than 40?
What is the square number larger than 40?
Between which two numbers does the square root of 40 lie?
This short, 5-minute conversation reinforced several important math concepts:
Prime numbers
Factors and divisibility
Square numbers
Square roots
I could have continued longer, but I decided to stop before their interest waned.
