Project 1 (Lesson 2 - Logical Thinking)
1. A story with four puzzles is given in this project. Divide the class into four
groups. Each group solves one puzzle and invents another puzzle similar
to what they have solved. The puzzles thus created are solved by other
groups. While solving the puzzle, the group should list out the information,
conditions, the goal and the solution steps. Of course, you also get a new
story in this project with the new puzzles created by you. Share the new
story created by your class with your friends and family.
The lost rabbit and the four puzzles
Jyoti, Tejas and their friends were searching for their rabbit
that was lost. As they were searching, they met a monkey who
was sitting and seriously counting again and again.
Children: Did you see a small rabbit walking this way?
Monkey: I saw the rabbit. The rabbit went in the direction
where you can find papayas.
Tejas: But where can we find papayas?
Monkey: I am going that way. I will show you. But first you
have to answer my question. I have called twenty friends
for dinner. Four want bananas, six want nuts, five want
coconuts. The rest want papayas. How many papayas
should I get?
