                    In Lyla in the Loop: Vacuum Hockey, players guide a robot by placing             Skills
                    arrows and boosters on a grid to reach the goal. It helps students learn step-by-step thinking
                    and fix mistakes by testing and improving their instructions.

                      FLOW OF INSTRUCTIONS

                      The flow of instructions means the order in which steps are followed. In an algorithm,
                      the instructions always flow in a particular direction, usually from top to bottom.

                      Just like reading a book, you start at the first step and move forward, one step at
                      a time. This is called the flow of control and shows how one step leads to the next.

                      Types of Flow

                      The flow of instructions in an algorithm can happen in different ways, depending on
                      the problem and the steps involved. There are three main types of flow. Let us look
                      at each one carefully.

                      Sequence

                      In sequence, the steps happen one after another, in a fixed order, from start to
                      finish. No choices, no repeating, just follow the steps straight through. This is the

                      simplest type of flow.

                      Example:
                      Problem: Making a glass of chocolate milk

                      Algorithm:

                      Step 1   Start

                      Step 2   Go to the kitchen and take a clean mug.

                      Step 3   Add two teaspoons of hot chocolate powder
                                into the mug.

                      Step 4   Pour hot water into the mug.
                      Step 5   Stir the mixture well with a spoon.
