2、4,324 + 1,342 = 524.31 + 42.34 =24,342 + 53,224 = 14.23 + 643.42 =三、进十加练习.6,798 + 5,463 = 456.80 + 755.30 =78.96 + 343.25 = 429.88 + 893.37 =7,459 + 83,953 = 89,873 + 33,449 =89,673 + 32,548 = 62.78 + 759.43 =2018年小学数学珠心算练习题：938.24 + 84.97 = 7,895 + 44,565 =四、破五进十练习6,757 + 7,667 = 568 + 14,686 =67.5
3、6 + 386.76 = 7,576 + 6,768 =3,275.86 + 69.67 = 3,576 + 74,968 =58.96 + 96.78 = 26.87 + 98.69 =57,768 + 12,686 = 7,685 + 36,769 =珠算减法练习一、直减法练习4,498 - 2,132 = 67,849 - 51,726 =6,398 - 5,266 = 97,649 - 82,615 =83,697 - 62,135 = 768.94 - 561.82 =82,976 - 61,955 = 98.74 - 63.51 =67,958 - 61,352 = 79,468
4、- 57,106 =二、破五减练习6,857 - 2,413 = 758.66 - 424.48 =5,768 - 1,324 = 7,586 - 3,142 =8,756 - 4,312 = 55,863 - 12,432 =865.76 - 441.32 = 86,755 - 42,312 =65,875 - 42,431 = 458.67 - 14.23 =三、退十减练习82,613 - 69,724 = 253.56 - 154.78 =110.29 - 33.47 = 325.65 - 146.87 =61,512 - 47,953 = 752.34 - 289.45 =925.41
5、 - 638.59 = 624.13 - 395.84 =73,221 - 49,387 = 84,321 - 75,498 =一般说来，“教师”概念之形成经历了十分漫长的历史。杨士勋（唐初学者，四门博士）春秋谷梁传疏曰：“师者教人以不及，故谓师为师资也”。这儿的“师资”，其实就是先秦而后历代对教师的别称之一。韩非子也有云：“今有不才之子师长教之弗为变”其“师长”当然也指教师。这儿的“师资”和“师长”可称为“教师”概念的雏形，但仍说不上是名副其实的“教师”，因为“教师”必须要有明确的传授知识的对象和本身明确的职责。四、退十补五减练习143.42 - 87.96 = 744.21 - 398.7
6、6 =344.32 - 89.76 = 612.34 - 467.79 =与当今“教师”一称最接近的“老师”概念，最早也要追溯至宋元时期。金代元好问示侄孙伯安诗云：“伯安入小学，颖悟非凡貌，属句有夙性，说字惊老师。”于是看，宋元时期小学教师被称为“老师”有案可稽。清代称主考官也为“老师”，而一般学堂里的先生则称为“教师”或“教习”。可见，“教师”一说是比较晚的事了。如今体会，“教师”的含义比之“老师”一说，具有资历和学识程度上较低一些的差别。辛亥革命后，教师与其他官员一样依法令任命，故又称“教师”为“教员”。52,314 - 26,867 = 824.31 - 379.86 =542.43 - 396.87 = 614.23 - 269.78 =84,132 - 49,687 = 53,424 - 46,968 =
