It took two hours to work, and Dad and his father put together the small flag of the label and inserted it in the pot. The little girl then went up with a ruler.

Because Dad told her that just inserting a small flag inside, it looks very monotonous, and in order to facilitate later observation, Dad asked her to make a good small scale for observation!

Of course, it is not a ruler to directly act as a small ruler. That's too creative!

The tools that Yang Lan gave to the cockroaches were a ruler, some small wooden sticks with the same small flag (previously used for hand-made materials left), double-sided tape, and a bag of colors with five different colors. Pagination note.

Obviously, the main body is still a stick and those sticky notes.

Just now, Dad told her about the usage of the ruler. The little girl was eagerly holding on the stick and marking the note.

Yang Wei gave the materials to the cockroach to study. He got up to go to the kitchen, cut the apples to eat cockroaches and cockroaches, and usually eat more fruits, not only to add water to the body, but also to supplement various vitamins and maintain the body's nutrition. balanced!

Of course, Xiao Yan also likes to eat apples. When Dad says that he wants to eat apples, the little guy will follow his father behind him and wait for his small head.

Yang Yan cut the skin of four apples in one go. Like the cut watermelon, he cut into a small petal and cut off the seeds in the middle of the apple. It was full of a large glass plate - the last time曦曦 Take the plate that washes the green beans.

"Taste!" Yang Lan turned and prepared to go to the living room, but the thought was like this. He reached for an apple and prepared to send it to his mouth, but turned around and just saw it and stupidly Standing next to him.

The short little man leaned back on his small head and stared at his father, his slightly open mouth, as if waiting for Apple to fly into his mouth. However, Apple is not expected to fly over, but the little guy has already slobbered out!

After Yang Xiao’s eyes on the little guy’s eyes, he looked at the apple in his hand that was about to be delivered to his mouth, and his heart suddenly rose into a strange feeling of guilt.

"Come on, wash your hands quickly, give you food!" Yang Xiao smiled, put the apple back, put the fruit plate aside, picked up the little guy, let him wash his hands, and handed him an apple.

Xiao Yan can finally eat the apple he likes to eat with satisfaction, tastes good, sour and sweet! The little guy grabbed an apple with two small hands, groaning, and following Dad's back, his eyes were full of coziness.

Back to the living room, Yang Lan saw that he was measuring the label with a ruler. Except that the ruler was a little oblique, the little girl was still doing something very seriously. Even her father and brother came over, she did not see it.

"What data did you measure?" Yang asked with a smile.

At this time, I looked up and slammed down the note, picked up the stick, and measured it to Dad. "Hey, I measured it! This stick is twenty centimeters long!"

"Yes, what about the width of the sign? What is the width of it?" Yang Yan looked at the action of aligning the stick with the ruler, nodded appreciatively, and then asked.

"This is very difficult, I think it is more than a centimeter." 曦曦 tangled, "a little more."

“How much is it?” Yang said softly. “Well, when we are studying science and mathematics, the answer is not ambiguous. How much is it, how much!”

So I put down the wooden stick, then picked up the sticky note and re-measured it to my father.

"You are not right in this way." Yang Lan saw that he once again put the ruler down (although not much), he put the fruit plate on the coffee table next to it, took the ruler and the note, and stroked it. The two long sides of the strip are aligned with the scale of the ruler. "You see, these lines are aligned to accurately measure the length between the two sides. You count, how many small cells are there."

He listened carefully to Dad’s explanation and put his head closer. The chin was pressed on Dad’s wrist to see: “One, two, three... twelve... Hey, there are twelve small grids. !"

"Do you see ten small cells between this centimeter?" Yang Xiao smiled.

I counted again and finally nodded seriously.

"A small cell is equal to 0.1 centimeter, 12 small cells, which is equal to one centimeter plus 0.2 centimeter, but we only need one centimeter, it is more, what should we do?" After understanding the numbers after the decimal point, I did not make too many explanations and simply asked.

"What should I do?" The little girl raised her brow with distress.

Xiao Yan was eating apples while watching Dad and his sister say something he couldn't understand. At this time, he finished eating the apple in his hand. The little guy licked the fruit bowl next to the coffee table and took the initiative. , grab one, then eat.

"Hey, let's lose more! Cut it off with scissors." He was still very clever. After trying to understand her father's problems, she thought of an idea.

"With scissors? It is not impossible, but the scissors are a little too dangerous for you. Can we think of an easier way?" Yang said with a smile.

This is an open topic. Yang Lan asked her to wash her hands, eat apples, and then think about it.

He also likes to eat apples. Just now, when the eyes are shining, my brother has been eating apples. She is also a bit unbearable.

However, the current front teeth can't bite anything. She can only open her mouth so much that she can plug the apple deep into her mouth and try to eat apples with dental caries without touching the front teeth.

Fortunately, Yang Lan took this problem into consideration and tried to cut the apple into small pieces. It doesn't have to be too hard to eat.

Of course, such a large pot of apples, not just cut to two little guys, Yang Lan also smiled and poked two pieces of food with a toothpick.

However, the scene before it is more interesting.

After seeing her sister's intervention, Xiaoyan didn't know if she was afraid that her sister had finished eating the apple. He stared at his sister and accelerated the speed of plugging the apple into his mouth.

Especially the efficiency of my sister’s apple, I’m so scared, I really worried that my sister would eat so fast, and I would rob the apple before the meal.

After a while, the little guy grabbed the second apple and stuffed it in his mouth, but he didn’t chew it in his mouth. As a result, he licked his face and ate it. He still had a hard time. I have to hold it.

"Okay!" Yang Lan felt that he couldn't smile and watch the movie again. He stretched out his hand and pulled a small squat and smiled. "You finish these before eating, so many apples, no one is talking." You grab it, and, not enough to eat Dad, go to the refrigerator and cut it for you!"

Xiao Yan only had time to chew the apple in his mouth. However, he still watched as he was caught by the father holding the apple in his little hand. He seemed to want to stuff his mouth.

"I don't eat! Give your brother to eat!" He was uncomfortable with his teeth. It was a little difficult to eat apples. This undoubtedly affected her appetite. Only after eating a few apples, I took a clap and clap my hands. Go to the kitchen to wash your hands.

"You see, my sister is not robbing you." Yang Lan then released Xiao Xiao's hand.

Sure enough, Xiao Xiao looked at his sister’s back and finally let go of his obsession, as he did before, slowly eating it.

But how much appetite does the little guy have?

After eating a few apples, Otaru was full of stomach and didn't want to eat it. The little hand rubbed it on his body and he ran to play next to it.

"Look, you have so much left, isn't Dad going to clean up the mess? Just now it looks like you have to finish it!" Yang Xiao smiled and pulled the little guy back and wiped him with a wet tissue. After rubbing, let him play with the buns.
