Question 1

What number comparison skills should first graders have?

Accepted Answer

First graders should compare two two-digit numbers based on the meanings of the tens and ones digits, recording the results with the symbols for greater than, less than, and equal to (CCSS 1.NBT.B.3). They should understand that when comparing two numbers, you first look at the tens place, and only if the tens are equal do you compare the ones place. This place-value-based reasoning is more sophisticated than the kindergarten approach of counting and matching. Worksheets that present pairs of two-digit numbers and ask students to write the correct comparison symbol build fluency with this skill. Students should also be able to order three or more numbers from least to greatest or greatest to least.

Question 2

How do you teach greater than and less than symbols to first graders?

Accepted Answer

Many teachers use the "alligator mouth" strategy: the open end of the symbol always faces the larger number because the alligator wants to eat the bigger meal. Draw two numbers with the symbol between them and show how the open side faces the larger number. Reinforce with place value understanding: compare tens first, then ones. Use base-ten blocks so children can see that 47 has more tens than 32. Worksheets that pair visual base-ten block representations with the comparison symbols help children connect the concrete to the abstract. Practice with both "which is greater" and "which is less" questions ensures children understand the symbol in both directions, preventing the common error of always reading left to right.

Question 3

Why is comparing numbers important in first grade math?

Accepted Answer

Comparing numbers develops place value understanding and number sense, both of which are critical for addition, subtraction, and problem solving. When a child can quickly determine that 67 is greater than 54, they demonstrate an understanding of how tens and ones compose a number. This reasoning supports estimation, mental math, and checking the reasonableness of answers. The comparison symbols (greater than, less than, equal to) are also used throughout mathematics, from simple number sentences through algebraic inequalities. Worksheets that progress from comparing single-digit numbers to two-digit numbers, and from using pictures to using only numerals, build this skill systematically across the first-grade year.
