This practical work was compiled by me for the 1st year students of the Pedagogical College studying the discipline "Informatics and ICT", in order to achieve the following goals:

To acquaint with examples of presentations closed in a cycle.

To teach how to organize a continuous cyclic demonstration of a presentation.

Learn how to set up an automatic slide change.

Repeat and fix pasting, copying, grouping, filling, rotating autoshapes using the program's drawing toolsPowerPoint.

Develop attention, logical thinking.

Students are invited to create a colorful presentation of a cyclic type called "Carousel" from 12 slides. A step-by-step procedure for performing the work is given. The first slide is created according to the sample, and each subsequent slide is obtained by duplicating the previous one. A continuous cyclic demonstration of the presentation is organized.

Practical work to be done in the program

Microsoft PowerPoint:

Creating a cycliccarousel presentations

Work progress:

Set the background format of the first slide.

Insert a figure ring.

(tab Insert, Group Illustrations - Figures - Basic figures - Ring).

Performing an insertrings, Shift so that the height and width values ​​of the shape are the same.

The shape can be resized by dragging the blue corner handle. In this case, to prevent the ring from becoming oval, hold down the key again.Shift .

Dragging the yellow diamond (anchor point) will affect the thickness of the shape.

Fill the shape

(chapter drawing tools, tab Format, Group Styles shapes - Shape fill) .

Insert a figure oval.

(tab Insert, Group Illustrations - Shapes - Basic Shapes - Oval).

Performing an insertoval, hold down the key while stretching the shapeShift to make a circle. Fill the shape.

Copy and paste 11 more of the same circles. Arrange them on the ring in the same way as the main divisions are located on the watch dial. Fill the circles with different colors.

Group the ring and 12 circles to get a single object.

To do this, press and hold the keyShift , at the same time select both shapes with the mouse and select on the tabDrawing Tools - Format - Group - Group.

In the future, we will rotate this construction of figures.

Create a triangular base. To do this, insert a figureisosceles triangle

(tab Insert, Group Illustrations - Figures - Basic figures - Isosceles triangle).

Reorder an elementisosceles triangle relative to other drawing elements on the slide

(chapter drawing tools, tab Format, Group Arrange - Send to Back). Fill the shape.

Form an object - a swing, using the insertion of shapes: line, arch.

Change the thickness of the lines (sectiondrawing tools, tab Format, Group Styles figures - Outline of the figure - Thickness - 4.5 pt) .

Customize the colors of the shapes and their outlines (sectiondrawing tools, tab Format, Group Styles Shapes - Shape Outline - Theme Colors) . Arrange the lines and the arch butt.

Create copies of the swing object.

Insert pictures of characters.

For example, you can use Microsoft Web Collection Pictures.

Group each character with his swing.

Set automatic slide change (tabAnimation, Group slide change) To do this, uncheck the box next to"on click". Next, in the automatic field, leave the time 00:00 sec. or set 00:01 sec.

The work on creating the first slide is completed.

To create the 2nd slide, duplicate the 1st slide (tabHome, Group Slides - Create Slide - Duplicate Selected Slides).

Then rotate the ring figure about 30clockwise (the colored circles will change their position), to do this, usegreen turn marker.

Now move the character swing to a new position and rotate it a bit.

Proceeding in this way (as in step 15), create 10 more slides. There will be 12 slides in total.

Each time you get a copy of the last created slide, rotate the ring again and change the position of the seesaw.

After creating all 12 slides, set upcontinuous cyclic demonstration of the presentation(tab slide show , Group Setting - Setting up the demo – Display Options ), to do this, check the box next to"continuous loop until key is pressed Esc » and press Ok .

Run the demo presentations.

In algorithms, commands are written one after another in a certain order.

Branching Algorithms

In life, you often have to make a decision depending on the current situation. If it rains, we take an umbrella and put on a raincoat; If it's hot, wear light clothing. There are also more complex selection conditions. In some cases, the fate of a person depends on the chosen decision.

The decision logic can be described as follows:
IF<условие>THEN<действия 1>OTHERWISE<действия 2>

Example:
IF you want to be healthy, then temper yourself, ELSE lie all day on the couch.

In some cases<действия 2>may be missing:

IF<условие>THEN<действия 1>

IF he called himself a loader, THEN climb into the back.

The form of organization of actions, in which, depending on the fulfillment or non-fulfillment of a certain condition, either one or another sequence of actions is performed, is called branching.

Let's depict in the form of a flowchart the sequence of actions of the 6th grade student Vasya Mukhin, which he imagines as follows: “If Pavlik is at home, we will solve problems in mathematics. Otherwise, you should call Marina and prepare a report on biology together. If Marina is not at home, then you need to sit down to compose ”(Fig. 60).

And so, with the help of a flowchart, you can very clearly present the reasoning when solving the following problem (Fig. 61).

Of the three coins of the same denomination, one is counterfeit (lighter). How to find it with the help of one weighing on a pan balance without weights?

Questions and tasks

1. What algorithms are called linear? Give an example of a linear algorithm.

2. Performer The calculator can execute only two commands: multiply by 2 and add 1. Think of the shortest algorithm for getting 50 from 0.

3. What form of action organization is called branching? Give an example of an algorithm containing branching.

4. Remember the plot of the Russian folk tale Geese-Swans. What conditions did her heroine have to fulfill? Think of other fairy tales where the characters had to make a choice that determined their fate.

5. Read an excerpt from J. Rodari's poem “What do crafts smell like? »:

Each case has a special smell:
The bakery smells of dough and pastries.
You go past the carpentry workshop -
It smells of shavings and a fresh board.
The painter smells of turpentine and paint.
The glazier smells like window putty.
The driver's jacket smells like gasoline
Worker's blouse - machine oil.

Paraphrase the information about professions using the words "IF ... THEN".

6. Out of 9 coins of the same denomination, one is fake (lighter). For what minimum number of weighings on a pan balance without weights can you determine it?

7. What form of organization of actions is called repetition? Give an example of an algorithm containing repetition.

8. In what literary works do you know there is a cyclic form of organization of actions?

9. Where will the performer who completes the following group of commands 16 times in a row end up?

walk 10 meters forward
rotate 90° clockwise

10. What group of actions and how many times should be repeated when solving the next problem?

Forty soldiers approached a river where two boys were rowing in a boat. How can soldiers cross over to the other side if the boat can hold only one soldier or two boys, but the soldier and the boy can no longer fit?

11. Recall the problem of the Calculator, which can only multiply by 2 and add 1. It will be much easier to develop rational (short) programs for it if you use the following flowchart:

Using this flowchart, write rational programs to get the numbers 1024 and 500 from the number 0.
