The class teacher has divided the whole class in group and assigned different projects. Ravi is the team leader of his group and he is overwhelmed with all the work. Suggest him two steps of computational thinking that will help him organise the tasks at hand.
Answers
Answer:
Algorithm - Say it with me: Al-go-ri-thm
A list of steps that you can follow to finish a task
Decompose - Say it with me: De-com-pose
Break a problem down into smaller pieces
Abstraction - Say it with me: Ab-strac-shun
Pulling out specific differences to make one solution work for multiple problems
Pattern Matching - Say it with me: Pat-ern Matching
Finding similarities between things
2) Figuring it Out
Tell your students that you want them to sum up all of the numbers between 1 & 200.
Use your body language to indicate that this is not a "serious" or graded exercise.
Now, let them know that they must do it all in their heads.
Add the time constraint of thirty seconds.
They may feel overwhelmed. This is intentional. You can indicate with your tone and demeanor that you might be crazy asking this of them, but begin timing with a resounding: "Starting NOW".
Watch the class as you keep time. How many are lost in thought?
When time is up, ask if anyone was able to get the total.
Ask if there is anyone who thought the problem was so hard that they didn't even attempt it.
Did anyone attempt it and just not finish?
What did they try?
Guide students toward thinking a little smaller.
If we break the problem up into smaller pieces, it becomes easier to manage.
Let's start at the two ends. What is 200 + 1?
What is 199 + 2?
What is 198 + 3?
See a pattern?
How many of these pairs will we have?
What is the last pair we will find? 100 + 101
That means that we have 100 total pairs.
If we have 100 total pairs of sums of 201, how do we find the final total?
What is 100 * 201?
Now, what if we wanted to find the
Answer:
Decomposition and Algorithn
design are the two steps that
will help Ravi to organize the
task at hand.
Explanation:
.Computational thinking is characterized
as the set of problem-solving
techniques that involve displaying
problems along with their explanations
or solutions that can be executed by a
Computer as well.
.It consists of five steps; Decomposition,
Pattern recognition, abstraction,
algorithm design, and debugging.
.In the given situation, the steps
that would help Ravi would include
Decomposition as it will help him
divide the task into smaller pieces
and algorithm design using which he
can instruct the members in steps to
complete the task successfully.
