Worksheet 2: Complete the table

#### Task:
- Complete the table by finding numbers that are 10 more or 10 less than the given numbers.

#### Solution:
1. Row 1: Number = 33
- 10 less: \( 33 - 10 = 23 \)
- 10 more: \( 33 + 10 = 43 \)

2. Row 2: Number = 63
- 10 less: \( 63 - 10 = 53 \)
- 10 more: \( 63 + 10 = 73 \)

3. Row 3: Number = 27
- 10 less: \( 27 - 10 = 17 \)
- 10 more: \( 27 + 10 = 37 \)

4. Row 4: Number = 80
- 10 less: \( 80 - 10 = 70 \)
- 10 more: \( 80 + 10 = 90 \)

5. Row 5: Number = 9
- 10 less: \( 9 - 10 = -1 \) (Note: This might be outside the typical range for young learners, but it's mathematically correct.)
- 10 more: \( 9 + 10 = 19 \)

Worksheet 3: Complete the sentences

#### Task:
- Complete the sentences by determining if the statements are true or false.

#### Solution:
1. Ten more than 15 is 25.
- True (15 + 10 = 25).

2. Ten less than 24 is 14.
- True (24 - 10 = 14).

3. Ten more than 25 is 35.
- True (25 + 10 = 35).

4. Ten less than 49 is 39.
- True (49 - 10 = 39).

5. Ten more than 58 is 68.
- True (58 + 10 = 68).

6. Ten less than 86 is 76.
- True (86 - 10 = 76).

7. Ten more than 73 is 83.
- True (73 + 10 = 83).

Worksheet 4: Colour the number square

#### Task:
- Colour the number square by following the instructions.

#### Instructions:
1. a) Colour 10 more than 17 red.
- 10 more than 17 is \( 17 + 10 = 27 \). Colour the number 27 red.

2. b) Colour 10 less than 45 blue.
- 10 less than 45 is \( 45 - 10 = 35 \). Colour the number 35 blue.

3. c) Colour 10 more than 63 green.
- 10 more than 63 is \( 63 + 10 = 73 \). Colour the number 73 green.

4. d) Colour 10 less than 84 orange.
- 10 less than 84 is \( 84 - 10 = 74 \). Colour the number 74 orange.

5. e) Colour 10 more than 71 pink.
- 10 more than 71 is \( 71 + 10 = 81 \). Colour the number 81 pink.

6. f) Colour 10 less than 98 purple.
- 10 less than 98 is \( 98 - 10 = 88 \). Colour the number 88 purple.

7. g) Colour 10 more than 49 yellow.
- 10 more than 49 is \( 49 + 10 = 59 \). Colour the number 59 yellow.
