Which is less, one or four?
We’re being asked to use a number line to
compare two numbers, the number one and the number four. Which of these two numbers is less? Number one comes before number four on
the number line. One, two, three, four. When we count from left to right on the
number line, the numbers increase. We start with the number with the least
value at the beginning of the number line. And the value of the numbers
increases. Four is worth more than one. One is worth less than four. One counter is less than four. The answer to the question “Which is
less, one or four?” is one. One is less than four.
