To practice listening to numbers, check out this video from my favorite nerd, Skunk Bear. You can use these listening questions below:
0:15 How old is the earth? How many zeros are in 1 billion?
1:02 How much does every inch represent?
1:18 When did life begin?
1:38 Where does photosynthesis start on the football field?
1:53 What happened 2.3 billion years ago?
2:50 How much time has elapsed? Where are we on the football field?
3:20 When did the meteor or earthquake happen? What was the result?
3:58 How far from the end of the football field are humans?
