After two hours of hard work, Xi Xi and her father finished making the small flag and inserted it into the flowerpot. Then, the little girl started to work on a ruler.
Her father told her that it would be very simple to insert a small flag into the flowerpot. In order to make it easier to observe later, her father asked her to make a small ruler for observation!
Of course, she did not want to use a ruler as a small ruler. That would be too uncreative!
The tools that Yang Yi gave Xi Xi were a ruler, some round wooden sticks similar to the small flag (these were leftover materials from when he gave them to Xi Xi), double-sided tape, and a bag of sticky notes with five different colors.
Obviously, the main materials were still the round wooden sticks and sticky notes.
Just now, her father had told her how to use the ruler, so the little girl excitedly used it on the wooden sticks and sticky notes.
Yang Yi gave the materials to Xi Xi to study first. Then, he got up and went to the kitchen to peel an Apple for Xi Xi and Tong Tong. Eating more fruits could not only replenish the body's water, but it could also replenish various vitamins and maintain the body's nutritional balance!
Of course, Tong Tong also liked to eat Apple. When he heard that his father wanted to eat Apple, the little boy followed behind his father and waited happily with his head raised.
Yang Yi peeled the skin of four Apples in one go. Like cutting watermelons, he cut the Apple into small pieces. He also removed the seeds in the middle of the apple and filled a large glass plate — the same plate that Xi Xi used to wash the green beans last time.
"Try it!" Yang Yi turned around and was about to walk into the living room. However, while he was thinking about this, he reached out and picked up a piece of Apple and was about to put it into his mouth. However, when he turned around, he saw Tong Tong standing behind him in a daze.
The short little boy raised his head and looked at his father eagerly. His mouth was slightly open, as if he was waiting for the Apple to fly into his mouth. However, Apple probably wouldn't fly over on its own, but the little guy was already drooling!
After Yang Yi looked at the little fellow's eyes, he looked at the apple in his hand that was about to be sent into his mouth. An inexplicable sense of guilt suddenly rose in his heart.
"Come, come, wash your hands quickly. I'll let you eat!" Yang Yi smiled and put the Apple back. He put the fruit plate aside, picked up the little guy, and let him wash his hands before handing him a piece of Apple.
Xiao Xiaofeng could finally eat his favorite apple contentedly. It tasted good, sweet and sour! The little guy held a piece of Apple in his two little hands. He chewed on it while following behind his father. His narrowed eyes were filled with contentment.
Back in the living room, Yang Yi saw Xi Xi measuring the labels with a ruler. Other than the fact that the ruler was a little slanted, the little girl was still very focused on her task. She didn't even notice her father and brother coming over.
"What data have you measured?" Yang Yi asked with a smile.
Xi Xi raised her head at this time. She excitedly put down the note, picked up the wooden stick, and measured it for her father. "Papa, I measured it! This stick is 20 centimeters long! "
"Yes, where's the note? What's its width? " Yang Yi looked at Xi Xi's action of matching the stick with the ruler, nodded with appreciation, and then asked.
"It's very difficult. I think it's more than one centimeter." Xi Xi said with hesitation, "A little bit more."
"How much is a little bit?" Yang Yi said softly, "Xixi, when we study science and mathematics, there is no ambiguity in the answer. Whatever the answer is, it's what it should be!"
Xi Xi put down the stick, picked up the note, and measured it for her father again.
"It's not right for you to measure it like this." When Yang Yi saw Xixi tilting the ruler again (even though it wasn't by much), he put down the fruit plate on the coffee table next to him and took the ruler and note. He gestured and aligned the two long sides of the note with the ruler's tick marks. "Look, only when these lines are aligned can we accurately measure the length between these two sides. You can count how many small squares there are in total."
Xi Xi listened to her father's explanation carefully. She also moved her head closer and pressed her chin on her father's wrist to look. "One, two, three … twelve … PaPa, there are twelve small squares!"
"Do you think there are ten small squares in this centimeter?" Yang Yi said with a smile.
Xi Xi counted again and finally nodded seriously.
"One small square is equal to 0.1 centimeters. Twelve small squares are equal to one centimeter plus 0.2 centimeters. But we only need one centimeter. What should we do if there is more?" Yang Yi thought that Xi Xi did not understand the numbers after the decimal point, so he did not explain too much and asked simply.
"What should we do?" The little girl frowned in distress.
Tong Tong ate the Apple while watching his father and sister talk about something he did not understand. At this time, he finished the Apple in his hand. The little guy glanced at the fruit plate on the tea table next to him, took the initiative to grab one and eat.
"PaPa, let's cut the extra ones! Use scissors to cut them off. " Xi Xi was still very smart. After she tried to understand her father's problem, she came up with an idea.
"Use scissors? It's not impossible, but scissors are a little too dangerous for you. Can we think of a simpler way? "Yang Yi said with a smile.
This was an open question. Yang Yi asked Xi Xi to wash her hands, eat the Apple, and then continue to think.
Xi Xi also liked to eat Apple. Just now, she caught a glimpse of her brother eating Apple from the corner of her eye, so she could not help but eat it.
However, Xi Xi's front teeth could not bite anything now. She could only open her mouth wide and stuff the Apple into the depths of her mouth. She tried to eat the Apple with her molars without touching her front teeth.
Fortunately, Yang Yi took this problem into consideration and tried to cut the Apple into small pieces. Xi Xi did not have to eat too hard.
Of course, such a big pot of Apple was not just for the two little guys. Yang Yi also smiled and poked two pieces with toothpicks to eat.
However, the scene in front of them was more interesting.
When Tong Tong saw his sister intervene, he was not sure if he was afraid that his sister would finish the Apple. He stared straight at his sister while stuffing the Apple into his mouth faster.
In particular, Tong Tong was frightened by his sister's efficiency of eating a piece of Apple in one bite. He was really worried that his sister would finish the whole plate of Apple before he was full.
After a while, the little guy grabbed a second piece of Apple and stuffed it into his mouth. However, before he could finish chewing, his face was smeared with Apple paste. He was eating very hard. It seemed that if his father did not care, he would choke.
"Okay, okay!" Yang Yi felt that he could no longer watch the show with a smile. He stretched out his hand and tugged at Tong Tong with a smile. "Finish this first, then continue eating. There are so many Apples. No one will snatch them from you. Also, if it's not enough, I'll go to the fridge to cut more for you!"
Tong Tong finally had time to chew the Apple in his mouth. However, he still looked at the Apple in his father's hand. It seemed that he still wanted to stuff it into his mouth.
"I don't want to eat anymore! Give it to Little Brother! " Xi Xi's teeth were uncomfortable, so it was difficult for her to eat the Apple. This undoubtedly affected her appetite. After eating a few pieces of Apple, Xi Xi clapped her hands and ran to the kitchen to wash her hands.
"Look, even your sister won't snatch it from you." Yang Yi let go of Tong Tong's hand.
As expected, Tong Tong looked at his sister's back and finally let go of his obsession. Just like before, he ate slowly.
However, the little guy did not have much of an appetite.
After eating a few pieces of Apple, Tong Tong was full and did not want to eat anymore. He wiped his little hands on his body and ran to the side to play.
"Look, there's so much left. Isn't it because I have to clean up the mess? You acted as if you wanted to finish it all! " Yang Yi laughed and pulled the little guy back. He wiped him with a wet tissue before letting him play with the steamed buns.
