It took two hours of hard work, Xixi and her father worked together to make the label-like little flag and insert it in the flower pot, and the little girl continued to compete with a ruler.

Because Dad told her that just a small flag was inserted in it, which looked monotonous, and in order to facilitate later observation, Dad asked her to make a beautiful small ruler for observation!

Of course, it is not a ruler that directly acts as a small ruler. That's so uncreative!

Yang Yi's tools for Xixi were a ruler, some round wooden sticks of the same style as Xiaoqi (leftover materials used to be used for Xixi's handwork), double-sided tape, and a bag of colorful paginated sticky notes with five different colors.

Obviously, the main body is still the round wooden sticks and those sticky notes.

Just now her father told her how to use a ruler, and the little girl enthusiastically took it and compared it on the sticks and sticky notes.

Yang Yi gave the materials to Xi Xi to study first, he got up and went to the kitchen, peeled apples for Xi Xi and Xiao Xi to eat, and usually ate more fruits, which can not only replenish water to the body, but also supplement various vitamins to keep the body's nutrition balanced!

Of course, Xiao Yu also likes to eat apples, and when he heard his father say that he wanted to eat apples, the little guy followed behind his father and waited with his little head on his back.

Yang Yi peeled the skin of four apples in one go, cut them into small petals like cutting a watermelon, and cut off the seeds in the middle of the apples, filling a big glass plate - the same plate that Xi Xi used to wash mung beans last time.

"Taste!" Yang Yi turned around, about to go to the living room, but thinking so in his heart, he reached out and picked up a piece of apple, ready to send it to his mouth, but turned around, and just saw Xiao Yu who was standing behind him in a daze.

The short little man looked up at his father with his little head tilted, and his little mouth was slightly open, as if he was waiting for the apple to fly into his mouth by itself. However, the apple probably won't fly over on its own, but the little guy is already drooling!

After Yang Yi looked at the little guy, he looked at the apple in his hand that was about to be sent to his mouth, and an inexplicable sense of guilt suddenly rose in his heart.

"Come on, hurry up and wash your hands and give you food!" Yang Yi smiled, put the apple back, put the fruit plate aside, picked up the little guy, asked him to wash his hands, and then handed him a piece of apple.

The little guy was finally able to eat the apple he liked to his heart's content, it tasted good, sweet and sour! The little guy grabbed a piece of apple in his two little hands, and while gnawing on it, he followed behind his father, and his squinting eyes were full of comfort.

Back in the living room, Yang Yi saw Xixi measuring the label with a ruler, except that the ruler was a little oblique, the little girl was still doing one thing very seriously, and she didn't even see her father and younger brother coming.

"What data have you measured?" Yang Yi asked with a smile.

Only then did Xi Xi raise her head, put down the note excitedly, picked up the wooden stick, and showed her father the measurement: "Baba, I measured it! This stick is twenty centimeters long!"

"That's right, what about the sticky note, what is its width?" Yang Yi looked at Xixi's movement of aligning the stick and ruler, nodded appreciatively, and then asked.

"It's so difficult, I think it's more than a centimeter. Xi Xi said tangledly, "A little more." ”

"How much is a little bit?" Yang Yi said softly, "Xixi, when we are studying science and mathematics, the answer is not ambiguous, how much it should be, how much is it!"

Xixi put down the stick, picked up the sticky note again, and re-measured it to her father.

"You're not right to do that. Yang Yi saw that Xi Xi had put the ruler crooked again (although the amplitude was not large), so he put down the fruit plate on the coffee table next to him, took the ruler and the sticky note, and compared it, aligning the two long sides of the sticky note with the scale line of the ruler, "You see, these lines are aligned to accurately measure the length between the two sides, you count, how many small grids there are." ”

Xixi listened carefully to her father's explanation, and also leaned her head closer, and pressed her chin on her father's wrist to see: "One, two, three...... Twelve ...... There are 12 small squares of poop!"

"Do you see if there are ten small grids in this centimeter?" Yang Yi said with a smile.

Xi Xi counted again, and finally nodded earnestly.

"One small grid is equal to 0.1 centimeter, and 12 small grids are equal to one centimeter plus 0.2 centimeters, but we only need one centimeter, and it comes out, what should we do?" Yang Yi estimated that Xi Xi still couldn't understand the number after the decimal point, so he didn't explain too much, and asked simply.

"What to do?" the little girl frowned in annoyance.

At this time, he finished eating the apple in his hand, and the little guy glanced at the fruit bowl on the coffee table next to him, so he took the initiative to go up, grabbed one, and then ate.

"Baba, let's cut off the extra ones! Xixi is still very smart, and after trying to understand her father's question clearly, she came up with an idea.

"It's not impossible to use scissors, it's just that scissors are a bit too dangerous for you, can we think of an easier way?" Yang Yi said with a smile.

This is an open-ended topic, Yang Yi asked Xixi to wash her hands, eat apples, and then continue to think.

Xixi also likes to eat apples, and just now she caught a glimpse of her brother eating apples all the time, and she couldn't help it.

However, Xixi can't bite anything with her front teeth now, so she can only open her mouth wide, stuff the apple deep into her mouth, and try to eat the apple with her molars without touching the front teeth.

Fortunately, Yang Yi took this problem into account and tried to cut the apples into small pieces, so that Xixi didn't have to work too hard to eat.

Of course, such a big pot of apples is not just for the two little ones, Yang Yi also smiled and poked two pieces with a toothpick next to him to eat.

However, the scene in front of me is more interesting.

After seeing his sister intervene, he didn't know if he was afraid that his sister would finish eating the apple, so he stared at his sister directly while speeding up the speed of stuffing the apple into his mouth.

Especially the efficiency of my sister's one apple in one bite, Xiao Yu was terrified, and I was really worried that my sister would eat so quickly that she would destroy this large plate of apples before he was full.

After a while, the little one grabbed the second apple and stuffed it into his mouth, but he didn't finish chewing it in his mouth, and he ended up with a pureed apple, and he ate it very hard, and it seemed that he was about to choke on it if Daddy didn't care.

"Okay, okay!" Yang Yi felt that he couldn't laugh anymore and watch the show, he stretched out his hand and pulled Xiao Yu, and said with a smile, "You finish eating these first, and then continue to eat, so many apples, no one will grab them from you, and besides, if you don't have enough to eat, Dad will go to the refrigerator to cut it for you to eat!"

Xiao Yu only had time to chew the apple in his mouth at this time, but he still watched with his eyes as his father grabbed the apple in his little hand, and seemed to want to stuff it into his mouth.

"I'm not going to eat it! give it to my brother!" Xixi's teeth were uncomfortable, and it was a little difficult to eat apples, which undoubtedly affected her appetite, so after eating a few apples, Xixi clapped her hands and ran to the kitchen to wash her hands.

"Look, my sister won't rob you. Only then did Yang Yi let go of Xiao Yu's hand.

Sure enough, Xiao Yu looked at her sister's back, and finally let go of her obsession, and ate slowly as before.

But where does the little one have a lot of appetite?

After eating a few apples, Xiao Yu's stomach was full, and he didn't want to eat it, so he wiped his little hand on his body and was about to run to the side to play.

"Look at it, there are so many left, isn't Dad going to clean up the mess for you?" just now he acted like you were going to finish eating!" Yang Yi smiled, pulled the little guy back, wiped him with wet wipes, and let him play with the buns.
