考點:自然數(shù)的認識,奇數(shù)與偶數(shù)的初步認識,合數(shù)與質(zhì)數(shù)
專題:整數(shù)的認識
分析:在小學階段最小的整數(shù)是0;在自然數(shù)中,是2的倍數(shù)的數(shù)叫做偶數(shù)(0也是偶數(shù)),不是2的倍數(shù)的數(shù)叫做奇數(shù),0是最小的偶數(shù),1是最小的奇數(shù);一個數(shù),如果只有1和它本身兩個因數(shù),這樣的數(shù)叫做質(zhì)數(shù),除了1和它本身還有別的因數(shù)的數(shù)叫做合數(shù),4是最小的合數(shù),2是最小的質(zhì)數(shù);據(jù)此解答.
解答:
解:最小的自然數(shù)是0;最小的整數(shù)是0;最小的偶數(shù)是2;最小的奇數(shù)是1,最小的合數(shù)是4,最小的質(zhì)數(shù)是2;
故答案為:0,0,2,1,4,2.
點評:本題主要是考查自然數(shù)、整數(shù),奇數(shù)與偶數(shù)、合數(shù)與質(zhì)數(shù)的意義.
