Write a short text
My family has four people. My mother is the first to get up every day because she likes jogging in the morning. My father is the second and he makes breakfast. I am the third to get up, and my little sister is the fourth. We eat together at 7:30. I love my family!
Tips for describing numbers:
Use cardinal numbers (1, 2, 3...) for counting and quantity.
Use ordinal numbers (1st, 2nd, 3rd...) for order and sequence.
