In social studies we put history cards in chronological order. The cards had a lot of the main events in the world. The first thing we did was decide what card was going to go first. Then we put the other cards in order. Then we checked in our notebook to see if we were right. We had trouble thinking where we should put grass invades Earth and we said it hase to go before apes walk on two legs we decided that because apes walked on two legs because of the grass. I learned that sometimes if  a card in a spot and your whole group agrees with were it is still check over it.
