During the National Day holiday, my mother and I went shopping in the supermarket to find kilograms and grams. Walking into the supermarket, we first came to the biscuit cabinet. Among so many dazzling cookies, I chose my favorite casual cookie. I looked at it carefully and finally found the "net content100g" in the corner, indicating that the weight of this packet of biscuits excluding the bag is100g. If there is100g,

Then we went to the place where we bought rice. I found that a bag of rice costs 10 kg. If our family eats 2 kilograms a day, our family will eat 60 kilograms a month, which is six bags of rice.

Later, I saw 16 eggs, about 1 kg, a pineapple about 2 kg and a watermelon about 3 kg.

Today, I have gained a lot. I feel the knowledge of kilograms and grams in mathematics. Mathematics is really important in life.
