Buy snacks

Monday, June 25th is fine.

Summer vacation came, and my parents took me back to my hometown. There are many snacks in my hometown, which are also delicious. Whenever I think of snacks in my hometown, I can't help drooling.

My mother took me to buy snacks that night. We bought two bowls of Camellia oleifera at 1 yuan each. Then I go to buy dough. We bought two bowls of 3 yuan each. Then I bought 20 stir-fried buns, each 0.2 yuan; Finally, I bought 10 pieces of fried tofu, and each piece was also 0.2 yuan.

That's great. The smell makes your mouth water. I really want to grab one and put it in my mouth, but my mother won't let me, saying it's unsanitary to eat like this. My mother and I walked back happily with a small fried bun in one hand and fried tofu in the other.

Dad saw that we bought a lot of delicious food from afar, and smiled and asked, "How much did it cost to buy so much?" My mother turned to me and said, "How much did you spend? Please report to my father. " I said loudly, "Camellia oleifera 2 yuan, Dough 6 yuan, Fried Bao 4 yuan, Fried Tofu 2 yuan. A * * * spent 14 yuan. The report is over! " Mom and dad all burst out laughing.

So much is 14 yuan. The snacks in my hometown are really delicious and cheap. If you come to our hometown, don't forget to have a taste!

go shopping

May 13? Saturday? It's sunny.

This afternoon, my mother and I went shopping in the supermarket.

When we finished buying what we needed, we were about to leave. I saw sausages on the shelf, so I asked my mother to buy some sausages, and my mother agreed. But just after a few steps, I saw a package with the same brand and weight on the shelf, which contained 10 pieces at 4.30 yuan each. Do you want to buy a pack or a slice? I hesitated. Suddenly, my mind turned and I understood. Just compare and see which one is cost-effective. So I started to calculate: if I buy 10 pieces in retail, each piece costs 40 cents, which is equal to 4 yuan, and the whole package costs 4.30 yuan, which is 3 cents more, so I decided to buy it in bulk. I told my mother the process of my calculation, and my mother praised me for my love of brains.

The next day, as soon as the students entered the classroom, everyone looked at the curriculum. It turns out that the first class is math. Everyone jumped with joy. After gymnastics, the bell rang and the students ran into the classroom. They can't wait for Miss Lin recently. As soon as Mr. Lin entered the classroom, he saw that all the students were full of energy and cheerful, and said, today we will learn pen subtraction and then explain it carefully. Finally, let's remember the most important point, one place is not enough to reduce from ten places. Now I have learned to add and subtract with a pen, and my knowledge is richer!

corner

Now we have learned the preliminary understanding of diagonal corners, and each corner has a vertex and two sides. Starting from a point, the ruler draws two lines in different directions, both of which can be drawn as an angle. Of the three angles on a triangle, 1 is a right angle, so drawing a right angle with a triangle can be done quickly and accurately. Many objects we use and see in our life have angles and right angles, such as a corner on a desk and chair, a big corner and two small corners on a red scarf, and all four corners of the national flag are right angles. We should use the knowledge taught by the teacher and know how to distinguish and distinguish.
