Let's go through each question on the worksheet:

1. 10 + 4 = 14
2. 10 + 2 = 12
3. 8 + 10 = 18
4. 10 + 5 = 15
5. 6 + 10 = 16
6. 3, 6, 9, 12 is counting in 3s
7. 32 sweets + 21 sweets = 53 sweets
8. 5 + 3 > 10 - 2 (Since $8 > 8$)
9. 9 tens and 1 unit = 91
10. 3, 6, 9, 12 (The pattern counts by 3s)
11. 10 fewer than 20 is 10
12. A cylinder has 3 faces (two circular faces and one curved surface)
13. Draw a line of symmetry down the middle of the square
14. To make 45 from 42, add 3
15. If 1 kg of flour costs €1, then ½ kg costs 50 cents (or €0.50)

Would you like any specific explanations for these answers or have further questions?

Here are five questions to expand on this worksheet:

1. How would you solve similar addition problems involving numbers greater than 20?
2. Can you think of other objects that have lines of symmetry similar to a square?
3. What are other examples of shapes with faces, like a cylinder?
4. How could we count by different numbers, such as 2s or 5s?
5. Why is understanding “fewer than” important in comparing numbers?

Tip: Practice counting by different increments (like 2s, 3s, 5s) to improve number pattern recognition skills.
