Find the place value and circle that digit Round 23. 11 to the nearest tenth Circle the number just after the decimal point
Move to the right, Underline it Look to the right of the number we have circled Underline the number.
0 through 4 Circle stays the same If the number we underlined is 0, 1, 2, 3, or 4, we leave the number in the circle as it is. 23. 11
Digits to the right, do not write them All the digits to the right of the number in the circle, do not write them
x 23. 15 23. 2 23. 11 is closer to 23. 1 rather than 23. 2
Find the place value and circle that digit Round 23. 77 to the nearest tenth Circle the number just after the decimal point 23. 77
Move to the right, Underline it Look to the right of the number we have circled 23. 77 Underline the number.
0 through 4 Circle stays the same If the number we underlined is 0, 1, 2, 3, or 4, we leave the number in the circle as it is. 23. 77
5 through 9, Add 1 in this game If the number we underlined is 5, 6, 7, 8, or 9 we add 1 to the number in the circle. 23. 87
Digits to the right, do not write them All the digits to the right of the number in the circle, Do not write them 23. 8
x 23. 75 23. 8 23. 77 is closer to 23. 8 rather than 23. 7
Round to the nearest tenth (1) 33. 67 = 33. 7 (5) 46. 99 = (2) 19. 72 = 19. 7 (6) 29. 67 = 29. 7 (3) 20. 75 = 20. 8 (7) 99. 90 = 100. 0 (4) 42. 93 = 42. 9 (8) 999. 97 = 1000. 0 47. 0
