Clock material picture-how to find the right picture for PPT

Pr describes in detail the production steps of watch animation and the movement effect of hour hand and minute hand. First draw the clock with PS (or download the front photo), and PR drops the hour hand, minute hand and second hand.

Second, draw the hour hand, minute hand and second hand with PS, and save them with PSD transparent bottom format.

Thirdly, in PR, the hour hand, minute hand and second hand are respectively on the upper video track of the clock material (one video track each), and the rotation special effects are added to the hour hand, minute hand and second hand through key frames to set the fixed point of rotation. The angle is a transition 359. The intervals of key frames are 12 hours, 60 minutes and 60 seconds respectively. (hour hand, minute hand, second hand)

How to find the right picture for PPT If PPT is to be generous and beautiful, then the picture must be of high quality. Where can I find high-quality pictures?

I have collected dozens of websites, but I can't start.

In fact, you just need to remember these four methods and you can search for pictures all your life.

Method 1: Associative divergent thinking

When I think of looking for pictures, the first channel I think of is Baidu picture search, but the problem is that many people don't know how to search for pictures.

Come on, let me test you. If you want to express "time", what keywords do you search for?

Don't tell me this is a clock!

If they are all clocks and watches, how can they be creative?

Want to try something literary?

Hourglass? Have you tried looking for an hourglass?

If you want to express a stronger sense of history, you can try the sundial.

Alas, I didn't expect to find that the photos are all ordinary, too ordinary.

Uh, how about this one below?

Feel it, this picture expresses the feeling of time travel, ok?

We have many ways to find good pictures, and the key is that we need to use them.

Associative divergent thinking

Many people ask him to find time. When he thinks of "clock" and "watch", the quality of the searched pictures will not be too high.

But we will use association to spread our thoughts. Think of sundials, hourglasses, time travel, time memory, vernal equinox, autumnal equinox, meridian and so on.

Well, in this case, you will find many different pictures, just like we found a picture of a hot air balloon when we searched for "time travel". At this time, we have a new inspiration. We can try "hot air balloon travel".

Hey, forget it, it feels really coming!

Learn to search for pictures with associative thinking, that is, come up with the exact keywords for the pictures you need. If not, it doesn't matter. Constantly adjust in the search process until you find the best one.

Like literary things?

Think about seasonal changes, such as the following?

This kind of good picture not only gives you a picture, but also gives you inspiration to match the big picture with words.

So remember, the first key to finding a picture: the training of associative divergent thinking!

Method 2: Combined keyword search

Now back to the keyword "clock", there is another big move!

These clock pictures, they look too ordinary, old illustration style? The first row is full of advertisements.

Then you see, what is the material I found?

Huh? The same Baidu, different results?

So, this is the second password to find the map:

Combined keyword search

I searched for "creative clock" and "simple clock"

Don't believe it? Try searching for "creative mouse".

How's it going? Isn't it great?

All right, let's do it again. Guess what keywords were used in this search?

Yes, it's a creative keyboard.

Hey, I mean to use combination keywords, but not all combination keywords use the word "creativity"!

Of course, creativity is a good word. Searching for "creative poster" and "creative design" can get a lot of inspiration, but what keywords should I add if I need a big picture?

"HD" or "wallpaper", of course. You see, the style of wallpaper is just different.

Friendly reminder, don't search for "beauty _ Kaka"

Do you know now? You can't find good pictures, not because there is no good website. But you should learn associative thinking and keyword thinking.

Everyone uses Baidu pictures. If you have strong associative thinking and pass the keyword skills, you will definitely find better picture materials.

Method 3: Commercial Gallery

But professional websites are also useful, because the picture quality is higher.

Here is a good map-finding website, Panorama Network:

The pictures of this website need to be purchased, and you can get super high-definition pictures after paying!

However, after you register your account, you can download the sample map for free (only there is a small watermark in the corner), and its clarity is enough to meet the needs of PPT.

Of course, it should be noted that if the work is used and printed commercially, the big picture still needs to be paid, and the small picture is just a sample.

What's cooler about panorama is the similar picture recommendation function, which allows you to find photographers in the same series of photos!

Isn't it cool?

The copyright of the pictures found on the Internet is unknown. It is not a big problem to use it in internal PPT without sharing it with others. But once it is commercialized, we should pay attention to copyright issues.

So there is something better below!

Method 4: Copyright Free Gallery

Copyright-free galleries, as the name implies, are free, and pictures also support commercial use.

Come on, let's get the website:

Feel the material of this gallery first.

There is also a surprise function, he can search for pictures according to color and feel it.

Of course, have you seen English words? For foreign websites, the keyword must be English when searching. The access speed may be a little slow, but compared with such a beautiful picture, slow is nothing.

English is really weak? There is also a baby website that you collect:

It supports direct input of Chinese for search.

Of course, if you want to get better search results, it is better to use English ~

By the way, share a designer's private website, where there are more than 300 excellent websites:

Have you learned all these map search skills?

Hurry and search ~

Know the clock courseware of the first grade of primary school.

The content of "knowing clocks and watches" has already had some cognitive experience in the first grade of primary school, and different students have different cognitive situations. Therefore, the teaching of this part of knowledge should be based on students' life experience, so that learning activities can be the summary and sublimation of students' life practice. At the same time, teachers should combine students' life experience in teaching, and more importantly, cultivate students' good habits of arranging time reasonably. In other words, not only the knowledge goal but also the emotional goal should be achieved. Here's what I'm trying to learn about the hour and half time of the clock:

I. Teaching process

1. Create a situation to stimulate interest. (5 points) Let students understand the relationship between clocks and daily life and the different forms of clocks and watches.

2. Participate independently and explore new knowledge. (25 points) Understand the whole time and half time by observing, operating, discussing and other methods, with the participation of multiple senses.

3. Apply new knowledge and solve problems. (10) Consolidate new knowledge through various forms of practice.

4. Summarize new knowledge, expand and extend. (1) Let students learn to sum up freely, and teachers should extend them appropriately.

Second, teaching clips and comments

Fragment 1

Teacher: (Each group has a clock model) These are clocks. What do you say they are made of?

Put forward the requirements of group cooperation:

1, observe carefully, every child should express his own opinion.

2. Choose a child to report as a reporter's representative group.

(Team members understand and observe the clock model, discuss and express their opinions) (3 points)

Health 1: There are numbers on the clock face, and a * * * has the number of 12.

Health 2: There are hands on the clock face, one is long, my mother says it is minutes, and the other is short, it is an hour hand. There is a longer one, which is minutes, but there is no one here.

Teacher: (The teacher made some supplements according to the students' answers) So have you figured out how these numbers 12 go? What's with the needles?

[Comment] Every student is familiar with clocks and watches and has a different understanding of them. Therefore, in teaching, I respect students' experience about clocks and watches, explore cooperative learning methods through observation, operation, discussion and communication, fully understand the external structure of the clock face, and lay a solid foundation for later learning.

The second part is to learn to recognize, read and write in the whole time.

1, to understand the existing knowledge structure of students.

Teacher: Son, can you tell the time displayed on the clock face? (Various situations of blackboard writing)

1:3 o'clock

Health 2: 12 points.

Teacher: What do you think of the time indicated by the clock face?

Health 1: Because the hour hand is at 3!

Health 2: But 12 still has a finger!

Health 3: But that's not an hour hand! The hour hand is at 3 o'clock and the minute hand is at 12, which means it is exactly 3 o'clock.

Teacher: The child speaks very well! We can also say it's 3 o'clock sharp. So what time are these two clock faces? How did you recognize it? )

I was born at 1:7, because the hour hand points to 7 and the minute points to 12.

Born at 2:6, because the hour hand points to 6. Minute hand pointing 12.

Teacher: The three clock faces we know just now all indicate the whole time. (blackboard writing: on the hour) so what are the characteristics of the direction of the hour hand and the minute hand on the hour? (group discussion)

Report:

These three minutes: all point to 12.

Clock hand:3 o'clock position, pointing to 3.

Point to 7 o'clock.

Point to 6 at 6 o'clock.

2. deskmate communication: how are you going to recognize the whole time?

3. The whole process is written in two ways.

(1) Introduce the usage of the Chinese character "time" (blackboard writing: 3: 07: 06)

(2) Teacher: How can I write accurately?

Guide students to use their existing life experience to discuss and come up with another way of writing?

(blackboard writing: 3:007:006:00)

4. Hands-on operation.

(1), dial the corresponding time on the clock face model.

(2) The teacher said that time was born on the clock face of the learning tool.

Content: 2: 07: 0011:0012: 00.

(3) deskmate interaction: one person tells the time and the other sets the clock.

[Analysis] It is difficult to identify the time indicated on the clock face in this lesson. Although students can know all the time in life, the concept is vague. Teachers arrange students' activities at different levels: trial recognition → observation and exploration → discussion and exchange → operation exercises. Perceive in operation, compare in observation and verify in communication, so as to find the law and break through the difficulties.

the third part

1, teacher: "Time is precious. We should cherish time. As students, how should we cherish time? Make rational use of time and arrange our day's study and life. Here is a timetable for children's day. Please read it carefully and then comment on whether his arrangement is reasonable? "

6: 30: Get up.

7 o'clock: Go to school.

8 o'clock: morning reading

8: 30: Exercise early.

9 o'clock: Class begins.

12: Have lunch

1: Class begins.

5 o'clock: sports activities

5: 30: Have dinner.

6 o'clock: evening study.

8 o'clock: go to bed

At this time, we should seize the opportunity to talk about the time in the morning and afternoon. )

2. (Courseware) One day, Xiaoming's students watched the video and said to each other, "When does Xiaoming do what?" They finished page 92 of the book. (Talk to each other at the same table and then choose to talk)

3. Game: Find friends.

It's 9 o'clock now. What time is it in an hour?

Inspire students to find out the time indicated by the original clock. Try it on your own clock face: when is an hour? Computer demonstration confirmation.

5. Ask and answer questions about life. You can ask students to investigate before answering. )

Didi will go to the stationery store to buy pencils and Xinhua Bookstore to buy books on Sunday. Didi looked at his watch, it was 7 o'clock in the morning and asked:

Should Didi go to Xinhua Bookstore or Stationery Store first? Why?

② How long before Xinhua Bookstore opens after the stationery store opens?

If Mr. Lei wants to buy pens and books at seven o'clock after dinner, which store should he go to first?

[Analysis] Exercise questions are rigorous in structure and diverse in forms, which conform to children's psychological characteristics and are conducive to students' intellectual development and ability training. In the exercise, the teacher arranged materials related to life background and situational questions and answers, which inspired students to solve problems around them with what they had learned, cultivated students' application consciousness, and embodied the connection between mathematics and life.

Third, the general comment:

Mathematics teaching should be based on students' existing life experience and knowledge. Understanding clocks and watches should be closely linked with students' life experiences to organize activities. Students' life experience is an important resource for primary school mathematics teaching. In fact, primary school students have rich experience in clocks and watches in their daily life. This is an important basis for primary school students to know clocks and watches. Therefore, in teaching, we can't regard knowing clocks, the hour and the half hour as "brand-new" knowledge. We should make full use of students' original clock experience and give full play to their initiative of group cooperation and independent exploration. Summarize that the teaching of this course fully embodies the educational concept of "student-oriented".

1. Respect students' cognition and let students enjoy "speaking". Students know something about clocks and watches, but they still have a little knowledge of some problems because of the sensibility of life. In the whole learning process, teachers always stand at the same height with students and guide students to explore learning. The understanding of the external structure of clocks and watches and the recognition of reading and writing all the time always let students tell what they know first, and then explore what they don't understand. Even if students don't understand, let other students talk about their own views and help other students with their own way of thinking and language. Respect students' existing life experience and build relevant knowledge structure on the basis of perceptual experience.

2. Respect the psychological characteristics of students and let them dare to "move". Throughout the class, let the students finish their study in action. Observation-eye movement, operation-hand movement, discussion-mouth movement, multi-sensory participation, one person moving, deskmate moving, four people moving, constantly experiencing success in sports, so that the mind is in a state of high excitement and actively completes learning.

3. Through the evaluation of Xiao Ming's schedule, the education of cherishing time is organically infiltrated; Help Didi complete the purchase task, experience the fun of using mathematics, and infiltrate the curriculum concept that mathematics comes from life and is applied to life.
