Compare Two-Digit Numbers - 1st Grade Math

1. What should you compare if two two-digit numbers have the same tens digit?

   Compare the ones digits. When tens are equal, the ones digit determines which is greater.

2. What symbol makes the statement true: $65$ __ $68$?

   $<$. $65$ has fewer ones than $68$ (same tens).

3. What symbol makes the statement true: $19$ __ $91$?

   $<$. $1$ ten is less than $9$ tens.

4. Which symbol makes the statement true: $48$ __ $43$?

   $48 > 43$. Both have $4$ tens, but $8$ ones is more than $3$ ones.

5. What comparison symbol makes this statement true: $90\ \square\ 99$?

   $<$. Same tens ($9$), but $0$ ones < $9$ ones.

6. What does the digit in the tens place tell you in a two-digit number such as $47$?

   It tells how many tens are in the number. The tens place is the left digit in a two-digit number.

    $>$. $10$ has $1$ ten, while $1$ has zero tens.

25. What is the ones digit in the number $47$?

    The ones digit is $7$. In two-digit numbers, ones digit is the right digit.

26. What is the tens digit in the number $47$?

    The tens digit is $4$. In two-digit numbers, tens digit is the left digit.

27. Which number is less: $90$ or $9$?

    $9$. $9$ has zero tens, while $90$ has $9$ tens.

28. Which number is greater: $99$ or $100$?

    $100$. $100$ has $10$ tens, while $99$ has only $9$ tens.

29. Find and correct the comparison: $68 > 86$. What is the correct statement?

    Correct: $68 < 86$. $6$ tens < $8$ tens, so use $<$ not $>$.

30. Which symbol makes the statement true: $70$ __ $7$?

    $70 > 7$. $7$ tens is much greater than $0$ tens and $7$ ones.

31. Which symbol makes the statement true: $56$ __ $65$?

    $56 < 65$. $5$ tens is less than $6$ tens.

32. What comparison symbol makes this statement true: $19\ \square\ 91$?

    $<$. $1$ ten is less than $9$ tens, so $19 < 91$.

33. Which number is greater: $48$ or $52$?

    $52$. Same tens ($4$ vs $5$), but $5$ tens > $4$ tens.

34. What symbol makes the statement true: $70$ __ $70$?

    $=$. Both numbers are exactly the same.

    $>$. $7$ tens is greater than $2$ tens.

42. Which number is greater: $59$ or $56$?

    $59$. $59$ has more ones than $56$ (same tens).

43. What does the digit in the ones place tell you in a two-digit number such as $47$?

    It tells how many ones are in the number. The ones place is the right digit in a two-digit number.

44. What comparison symbol makes this statement true: $78\ \square\ 65$?

    $>$. $7$ tens is greater than $6$ tens, so $78 > 65$.

45. What place value should you compare first when you compare two two-digit numbers?

    Compare the tens digits first. The tens place has greater value than the ones place.

46. If two two-digit numbers have the same tens digit, which digits do you compare next?

    Compare the ones digits next. When tens are equal, ones place breaks the tie.

47. What does the symbol $>$ mean when comparing numbers?

    $>$ means "greater than." The open side points to the bigger number.

48. What comparison symbol makes this statement true: $29\ \square\ 23$?

    $>$. Same tens ($2$), but $9$ ones > $3$ ones.

49. What symbol makes the statement true: $58$ __ $52$?

    $>$. $58$ has more ones than $52$ (same tens).

50. Which number is less: $73$ or $37$?

    $37$. $3$ tens is less than $7$ tens.

51. Which symbol makes the statement true: $38$ __ $38$?

    $38 = 38$. Same tens and same ones means equal numbers.

52. Which number is less: $26$ or $62$?

    $26$. $2$ tens is less than $6$ tens.

53. Which symbol makes the statement true: $40$ __ $40$?

    $40 = 40$. Same tens and same ones means equal numbers.

54. What comparison symbol makes this statement true: $34\ \square\ 56$?

    $<$. $3$ tens is less than $5$ tens, so $34 < 56$.

55. Find and correct the comparison: $54 < 45$. What is the correct statement?

    Correct: $54 > 45$. $5$ tens > $4$ tens, so use $>$ not $<$.

56. What comparison symbol makes this statement true: $42\ \square\ 42$?

    $=$. Same tens and ones digits mean the numbers are equal.
