1. The arrival: The camp looked beautiful — green forest, blue sky, a stream nearby.
2. The tent disaster: While Sam was putting up the tent, the rain started. By the time they finished, they were soaking wet.
3. The fox: While Maya was cooking sausages on the camp fire, a fox ran out of the bushes and took them. All of them.
4. The map: They decided to explore the forest. When they finally checked the map, they realised they were holding it upside down. They were completely lost.
5. The stream: While Leo was trying to cross the stream on some rocks, he slipped and fell in. He was not hurt, but he was soaking and his shoe floated away.
6. The view: While they were looking for Leo's shoe, they suddenly found a clearing with the most beautiful view — rolling hills and the sunset. They all stopped and looked.
7. The return: When they finally got back to camp, Miss Carter was standing at the entrance with hot chocolate and biscuits. Nobody said anything. They just drank the hot chocolate.
8. The verdict: That night, sitting in the tent, Sam said: "That was the worst day of my life." Leo said: "Me too." Maya said: "Shall we do it again next year?" They all laughed.
Draw a long horizontal line (the background action) and a short vertical arrow cutting through it (the interrupting event).
"While Sam was putting up the tent," ————————→ (long action, in progress)
"it started to rain." ↓ (short sudden event, interrupts)
This one image explains 80% of the grammar. Students can always come back to it.
while + Past Progressive (action in progress):
"While Maya was cooking, a fox appeared."
when + Past Simple (event happened, then another):
"When we arrived, it was already raining."
Both are also possible with Past Simple + Past Simple (sequence):
"When the fox ran out, Maya screamed." (one thing, then another)
Key error: ✗ "While Sam put up the tent, the rain started." → This is possible but loses the "in the middle of doing" meaning. ✓ "While Sam was putting up the tent…" is more precise and at a higher level.
Positive: was/were + verb + -ing · Negative: wasn't/weren't + verb + -ing
"I was walking." · "They were cooking." · "She wasn't listening."
Question: Was/Were + subject + verb + -ing?
"Was it raining when you arrived?" · "Were they looking at the map?"
Common errors:
✗ "I was walk." → ✓ "I was walking."
✗ "They was cooking." → ✓ "They were cooking."
✗ "While Maya cooked, the fox appeared." → better: "While Maya was cooking…"

Reading
ReadingToday was the most difficult day of my life. While I was putting up the tent, it started to rain. By the time I finished, I was completely soaking. Maya was trying to cook the sausages on the camp fire, but then a fox appeared and took them. We had biscuits for dinner. Tomorrow will be better. (I hope.)
I cannot believe today. I was standing at the camp fire. The sausages smelled amazing. I was thinking about how good dinner was going to be. And then — BOOM. A fox ran out of the bushes. While I was watching in total shock, it grabbed all six sausages and disappeared. Six sausages. I had been cooking those sausages for twenty minutes. I wasn't even angry. I was just amazed. The fox was very, very fast.
I need to write about yesterday. While we were walking through the forest, we got lost. I decided to cross the stream on the rocks to look for the path from the other side. While I was crossing, I slipped. I fell into the cold water. My shoe floated away. I walked back with one shoe. Unfortunately, nobody stopped laughing for about ten minutes. But then — while we were looking for my shoe — we found the most beautiful view of our lives. Maybe it was worth it. Maybe.
