Step-by-Step Solution:
####
1. 1 more than 30
-
Visual Representation: The image shows 30 blocks, and we are asked to add 1 more block.
-
Calculation: \( 30 + 1 = 31 \)
-
Answer: 1 more than 30 is
31.
####
2. 1 less than 30
-
Visual Representation: The image shows 30 blocks, and we are asked to remove 1 block.
-
Calculation: \( 30 - 1 = 29 \)
-
Answer: 1 less than 30 is
29.
####
3. 1 more than 39
-
Visual Representation: The image shows 39 blocks, and we are asked to add 1 more block.
-
Calculation: \( 39 + 1 = 40 \)
-
Answer: 1 more than 39 is
40.
####
4. 1 less than 39
-
Visual Representation: The image shows 39 blocks, and we are asked to remove 1 block.
-
Calculation: \( 39 - 1 = 38 \)
-
Answer: 1 less than 39 is
38.
####
5. 10 more than 27
-
Visual Representation: The image shows 27 blocks, and we are asked to add 10 more blocks.
-
Calculation: \( 27 + 10 = 37 \)
-
Answer: 10 more than 27 is
37.
####
6. 10 less than 33
-
Visual Representation: The image shows 33 blocks, and we are asked to remove 10 blocks.
-
Calculation: \( 33 - 10 = 23 \)
-
Answer: 10 less than 33 is
23.
