Detailed description:

When we want to tell the computer how to perform some task, we give it detailed, step-by-step instructions. These instructions are together called a program. A program is usually written in a programming language, which consists of some special keywords that the computer can understand. In future lessons, we will use a programming language called Logo to make the computer perform simple tasks. In this lesson, we will have an activity in which the students, without being aware of it, will follow a process similar to programming in Logo.

The activity we will do for this lesson is called the Hopping game. The game is played as follows:

● A grid is drawn on the floor and the centre square is marked.

● Two to three objects are taken and placed on other squares of the grid. These could be balls or sweets or any small thing that the class finds attractive.

● Two students will play the game together. One student stands on the centre square. He will try to move to the squares with the objects in them and pick them up. But he can only move by hopping according to the instructions of his partner.

● The partner stands at the edge of the grid and gives directions. He can only use the following four instructions to guide his hopping friend:

1. Move forward by some number of squares

2. Move backward by some number of squares

3. turnright

4. turnleft 

● The game ends after all the objects in the grid have been retrieved

Detailed Description

When we want a computer to do something, we must give it clear, step-by-step instructions. This set of steps is called a program. We write programs in a programming language. This language has special words that the computer knows. In later lessons, we will use a language called Logo to do simple tasks. Today, we will play a game that works just like Logo programming.

The game we will play is called the Hopping game. Here are the rules of the game:

• Draw a grid on the floor and mark the middle box.
• Place two or three fun items, like sweets or toys, on different boxes of the grid.
• Two players play together. One player stands in the middle box. This player must hop to the other boxes to collect the items, but only by following the partner's instructions.
• The partner stands on the side of the grid and gives commands. The partner can only use these four commands to help:
  1. Move forward by a set number of boxes
  2. Move backward by a set number of boxes
  3. turnright
  4. turnleft
• The game is finished once all the items are collected.

Grid Game Example and Guidelines

For example, look at the grid above. The cross shows where the player starts. The letters A, B, and C are the three items. Here is one way to tell the player to collect the items in that order:

forward 1
turnleft
forward 1 (pick up A!)
backward 3
turnleft
backward 1 (pick up B!)
forward 4
turnright
forward 2 (pick up C!)

There are many other ways to collect the items in this grid.

Lesson Plan

The Hopping game is a fun play activity, so you do not need to explain too much at first. Here are some helpful tips for the teacher:

• Try playing in a room with square floor tiles. This makes drawing the grid very easy, as you only need to mark the outer borders.
• Ensure the grid is a good size. A 7x7 or 9x9 grid is usually best.
• Use fun items that children like, such as chocolates or sweets, which they can eat together when the game ends.
• Make sure all children get a turn to give commands or be the hopper.

Worksheet

Question 1. Where will the turtle be after following these instructions? Trace the path with a pencil and draw a turtle in the last square. One example is shown below:

a.
forward 4
turnleft
forward 4

b.
backward 4
turnright
forward 4
turnleft
forward 4
turnright

c.
forward 2
turnright
forward 2
turnright
forward 2
turnright
forward 2
Answer:
a. The turtle starts at the bottom-right corner (Column 5, Row 1). It moves 4 squares forward to the top-right corner (Column 5, Row 5), turns left, and moves 4 squares forward. It ends at the top-left corner (Column 1, Row 5) facing left.
b. The turtle starts at the top-left corner (Column 1, Row 5). It moves 4 squares backward to the bottom-left corner (Column 1, Row 1), turns right to face right, moves 4 squares forward to the bottom-right corner (Column 5, Row 1), turns left to face up, moves 4 squares forward to the top-right corner (Column 5, Row 5), and finally turns right. It ends at the top-right corner (Column 5, Row 5) facing right.
c. The turtle starts at Column 3, Row 4. It moves 2 squares forward, turns right, moves 2 squares forward, turns right, moves 2 squares forward, turns right, and moves 2 squares forward. This forms a square path, bringing the turtle back to its starting position at Column 3, Row 4.
In simple words: Follow the steps one by one. The turtle moves along the grid lines and turns left or right.

Exam Tip: Be careful with the starting direction of the turtle. Remember that "forward" is the direction the turtle is facing, and "backward" is opposite to it.

Question 2. Help the hungry turtle reach the carrots! Fill in the correct numbers in the blanks. [Hint: first trace the path, then count the squares.]

forward ___
turnright
forward ___
Answer:
forward 2
turnright
forward 4
In simple words: The turtle goes forward 2 squares. Then it turns right and goes forward 4 squares to reach the carrots.

Exam Tip: Always count the number of grid lines or squares carefully to make sure the turtle does not stop too short or go too far.

Question 3. The green turtle and the red turtle want to meet in the centre square. Can you write simple instructions for each of them so that they reach the square?

Answer:
Green turtle instructions:
forward 1
turnright
forward 2

Red turtle instructions:
forward 2
turnright
forward 2
In simple words: The green turtle moves up 1 square and right 2 squares. The red turtle moves down 2 squares and right 2 squares to meet in the middle.

Exam Tip: When writing paths for multiple turtles, double-check the initial facing direction of each turtle to determine whether a turnright or turnleft is needed.
