In the evening, my brother said he was hungry and wanted to drink milk powder. Seeing my mother washing clothes, I helped my brother make milk powder. But I didn't know how much water and milk powder I needed, so I ran to ask my mother. Mom told me that I need 180 ml of warm water.

I asked my mother how many spoonfuls of milk powder she needed. My mother said, "How many spoonfuls of milk powder do you need for 30 ml of warm water, 1 80 ml of warm water? Calculate it! " When I added it, I counted 30: 30+30 = 60, 60+30=90, 90+30= 120, 120+30= 150,150+30.

Finally, the sixth 30 adds up to 180. I quickly told my mother that it was six spoonfuls. Mom smiled and said, "That's right, but if you learn multiplication and division, it will be easier to calculate.". 180÷30=6, which can be calculated soon. " It can be that simple!

Mathematics is around us, I want to study it well!

Math diary, model 2.

Happy Saturday came, and my father and I went to work in the shop.

As soon as I arrived at the store, my father got a call from a customer. I wanted to buy a batch of plates and put them on the insulation table. Dad answered the phone and said to me, "Dad tested you today!" " ! The customer wants to buy 4 fractional pots on the heat preservation table. 1 There are 6 fractional pots on the heat preservation table. A * * *, how much do you want? "I think in my mind, 6+6+6 = 24 (a).

Dad asked again, "Is there any other convenient and quick algorithm?" On second thought, I just learned the multiplication formula "4624" in the summer vacation, and I soon figured it out, which is the same as the answer to addition. Dad gave me a thumbs-up when he heard the answer. Dad said, "The number of pots in our warehouse is 12. How many boxes do we need to send? "

I quickly meditated in my mind that 24- 12- 12 = 0 is exactly two boxes. I quickly said to my father, "two boxes will do." Dad smiled happily and invited me to eat ice cream.

It turns out that mathematics is everywhere in our lives.
