翻开以前的小一小二贴子都说数学很容易,几年前老大上小一时也有同感,以下是老二这个学校假期的数学作业,上学还不到三个月,就做这样的题目感觉比老大那时学的要难多了,请大家帮忙看看是不是每间学校都是做这样的题?
1) There are 5 cows and chickens altogether. A caw has 4 legs and a chicken has 2 legs. How many cows are there if there are 14 legs altogether?
2) John had some marbles. He gave 6 marbles to Ali and bought 4 more. If he has 14 marbles now, how many marbles did he have at first
3) Study the number pattern and complete the number in the blank.
