OVERVIEW:
In this course, we have prepared the simplest way to teach kilogram and gram units in concrete terms, as it will not be easy and understandable for our students who are younger, as each student learns the concept of justice through the tale and the importance of justice. At the same time, we wanted to show that where the substance occupies, and the size and weight it appears to be, are different things. We will explain that a substance can be light, even if it takes up a lot of space, or, on the contrary, it may be very heavy, although it seems small. We set out from the concept of justice to explain this. We tried to give these concepts with fairy tale. For them, these concepts were important concepts to be learned. Thus, they will design a scale based on the concept of justice, which is the main idea of the tale. They will have learned weight measurement devices. What is the weight? Is the weight measured? So how do we measure it? They will have found the answers to their questions and will learn the concepts of "heavy, light, equal." Our students, whose ages are 9,10,11, will learn the concepts of weight measurement in kilograms and grams. Thus, students will learn the relationship between scales and justice, and their teachers and friends will share their experience during design.
SCENARIO
LEARNING ACTIVITY
The fairy tale containing the daily life problem below is read to the children;
“The old man's wife was making butter at home. Her husband, on the other hand, took them to and near the grocery store every day, and they got along with him. The grocery store never weighed the butter that the man brought. But one day he said, "I wonder," after the man left, put his butter on the scales. When he saw that it was 900 grams, he was very angry and said, "When he comes tomorrow, he will account for it and do not shop from him again." The next morning the old man came in with butter in his hands and said, "I will not buy butter from you again," with a hard look at the grocery store. "Did I have a mistake, sir?" Said the old man sadly. "I weighed the butter that you brought me, 900 grams came, shame, isn't it?" Said the grocery store. The old man embarrassed and bowed his head and said, "Sir, we don't have a scale, we bought a kilo of sugar from you, we use it as a scale." He was surprised at what to do from the grocery shame. (Anonymous)"
Design-oriented thinking, empathy map questions are asked;
• Why is the grocery store embarrassed according to the table?
• What would you do if you were the old man in the fairy tale?
• Which word is the synonym of the tart in our beautiful Turkish?
• Would you use the word Libra in a sentence?
• Have you ever heard the word justice? If you heard, what do you think is justice?
• Can we use another word instead of the word justice? Which word can we use?
• Should we be fair? Why should we be fair?
• Do you think there is justice where there is a scale?
• What did the grocery store do, according to the table, that the man weighed the butter incomplete?
• What would you do in this situation if you were in the place of the old man in the fairy tale and did not have a balance?

EXPLANATION
We find the amount of assets around us by weighing. The weighing unit is "kilogram" and "gram". We measure the amount of large objects with "kilogram" and the amount of small objects with "gram". Another name for the amount of substance is mass. The amount of the substance is measured by scales. The amount of the substance is measured with equal lever scales used for weighing vegetables in greengrocers or in the market.
Show your students the animals in the picture. Then continue to explain. Some of these are less than 1kg. For example, butterfly, bee, frog, snail and caterpillar. Apart from that, flies, birds, mosquitoes and spiders can be given as an example to animals less than 1 kg.
Examples of animals larger than 1kg are dogs, cats, ducks, dolphins, monkeys, whales, sheep, and cows. These are large animals and their amount is greater than 1kg.
Show your students images and continue explaining. As you can see, the amount of substance in the encyclopedia is higher than the eraser. Because the encyclopedia comes about 2kg, but the eraser comes about 30 grams.
We should always measure large objects in kg. We measure the small ones with gr. Remember, friends 1kg = 1000 g (i.e. 1 kilogram comes 1000 grams).
Now, let's continue our narration by making another example.
Since some vegetables are large, we measure them in kg. Some vegetables are small and we measure these vegetables in grams. Examples of large vegetables are watermelon, melon, zucchini and white cabbage. Bananas, plums, strawberries, cherries, cherries are small, they are given in grams.
Optional; You can duplicate the questions if you wish.
•… kg… .. must be used to measure the table. like
• The piano is too large… must be measured with ……….
• 10 cents is very small.
• The paper clip is very small and must be measured with …… ..
• The tennis ball is small, it should be measured with …… ..
• The button is small. It should be measured with …… ..

EXPLORE
In this section, you can have students brainstorm by asking questions to discover.
Now I want you to help the old man in the fairy tale, let's ask the following questions.
How can we help the old man?
- How do you think the old man would have a scale?
-Can you design a scale with the materials at home?
- What could be the materials at home?
- Of these materials; Would you design a scale with materials such as string, paper cup bowl garbage skewer hanger etc.?
Tell them to prepare the materials.
Encourage design with materials.
NOTE: If your students are having trouble finding their own design ideas, show them the following images for design. Tell them to do it under your guidance.
- Measure some objects on the scale you designed.
Say it using the concepts of heavy, light and equal.
- Ask older students (3rd and 4th Grades) to say with the concepts of kg and gram. For example, as the pen is measured in grams.

DESIGN STAGE
1) Let's ask our students to pass the ropes with their children with the help of their parents and let them get tied up.
2) Let's tie our bowls to both sides of our hanger.
3) Put our hanger on the door handle, etc. Let's hang it in a place where it will balance. Next, let's start weighing objects or entities.
4) Let's explore what is lighter and heavier together.
EVALUATION
Ask your students the following questions after the design is finished;
1-Did your design meet the need of the old man?
2-Which part of your design measures objects or entities?
3-What are the pet cup bowls in your design?
4-We used the clothes hanger in your design. What did this provide?
Why did you hang your design on the arm of a door at home?
6-Can we measure the objects with another tool?
Record the answers to the questions on a piece of paper.
