| 1 | C) 8 | Count all the stars: ⭐⭐⭐⭐⭐ (5) + ⭐⭐⭐ (3) = 8 stars |
| 2 | B) 30 | After 29 comes 30. We count 28, 29, 30, 31... |
| 3 | B) 54 | Compare the tens digit first. 54 has 5 tens, which is the most. |
| 4 | C) 50 | In 52, the digit 5 is in the tens place. 5 tens = 50. |
| 5 | B) 10 | Counting by 2s: 2, 4, 6, 8, 10. Each number is 2 more. |
| 6 | A) 67 | 67 is smaller than 76. Compare tens: 6 tens < 7 tens. |
| 7 | C) 4th | Ahmad is 3rd. Mei Ling is right behind (one place after), so she is 4th. |
| 8 | B) 43 | 4 tens (🔵) = 40, and 3 ones (🔴) = 3. So 40 + 3 = 43. |
