6月14日第3题详解此题选E。
这一题要考虑到三方面，一是数的大小变化，这回数宝宝们不再是一个一个变大了，而是两个一组，3比1大2,4比2大2，所以第3组应该填5,5比3大2。
二是图形的变化，图形的变化是红圈圈、黑正方、白三角，所以填白三角。
三是数的颜色变化，它们的顺序是白红黑，所以数的颜色填黑色。
6月15日第4题答案详解此题选A。
这一题观察答案很快发现所有的答案都是12，所以可以暂时不考虑数的大小变化。
（聪明的宝宝一定发现了它的规律，就是后面一个数总比前面那个大2）跟前面几题类似，这一题要考虑到：1、图形形状的变化，方圆方圆方圆，所以答案为圆~2、图形填充颜色的变化，白蓝白蓝白蓝，所以答案为蓝色~3、数宝宝的颜色变化，黑红黄、黑红黄，所以答案为黄~6月16日 第6题详解：此题选B。
很容易发现，有两种颜色的数宝宝~黑色组：1、2、3，蓝色组：1、3、5，相信一直跟进的宝宝们都发现了黑色组的数是加1加1的变大，蓝色组的是加2加2的变大，而且总是一黑一蓝，那么接下来出现的数是黑色。
既然是黑色，我们就只看黑色组的变化，黑色组将要出场的是4，所以答案为黑色4。
6月18日~第7题详解：此题选A。
我们先来观察外面的图形，圆方圆方圆，那么接下来出现的肯定是方~这一点你想到了吗？既然是方，那么我们可以单看方，你会发现方里面出现的是1和2，2和4，那么接下来就应该出现3和6，对吧？也有聪明的宝宝会说，圆和方一起考虑，每一个方里的数宝宝都和它前面那个圆里的是一样的~这两种观察方法都可以~~确定下来是3和6，就只剩下A和C了~到底是A还是C呢？它们俩的区别就是谁在红色的地方，谁在白色的地方~你可以盯着红色的来找规律，前面两个圆中红色的都是小的那个数，所以应该是3在红色的地方~~嗯~还有眼睛亮的宝宝会说，红色地方的数跟在黄色地方的数是一样的~前面那个圆中黄色中的是3，说明后面方里面红色地方也是3~~咱们找规律有好多好多种思考的角度~~只要你说的有道理，就是对的~~赶快跟上我们的步伐，一起来发现其中的奥秘吧~~6月19日~第8题详解：此题选E.先观察图形，咱们很快就发现规律，圆方圆方圆，那么接着肯定是方~只排除了A。
既然是方，那我们仔细观察方有什么规律，嗯，我们发现方肚子里的是横线，不是竖线，对不对？所以又排除掉了一个答案D。
就剩下BCE。
它们三个的区别就在于里面的颜色啦~我们的目标就剩下颜色的规律~嗯，好~这个时候，你发现没有，如果只看方块中的颜色，似乎没有规律，黑红、红黄，很难判断下一个方块中的颜色。
既然单独看方块行不通，那么我们试着把方块和圆里的颜色连在一起看看~哈哈，我们发现黑红黄黑红黄黑红~那么接下来出现的应该是黄黑~所以答案是E~宝宝们，我们这一题的难度在颜色的规律上，这回颜色很调皮，没有规规矩矩地呆在同样的图形中，要你能够眼睛不看形状的变化，单单只看颜色的变化~这个本领你学会了吗？要多多修炼喔~6月20日第9题详解：此题选D.可爱的小乐包们，你们选对了吗？这题是我们以后经常会碰到的一种找规律的类型喔~我们一起来观察吧~放眼望去，相信所有的聪明的宝宝都能发现图形没有变化，都是方块~而且，里面颜色的种类也没有变化，都是黑红白蓝~~只有颜色的位置发生了变化，对不对？好，我们开始研究颜色的位置到底有什么规律。
有的宝宝就说啦，这么多的颜色都在变化，一起观察眼睛都花了，所以，我们先单独盯着一种颜色看。
那就选黑吧~你会发现黑色是按照顺时针的方向变化的~黑色肯定是在左下角。
ps：这里粑粑麻麻们可以在纸上画田字格，标出1234四个位置，黑色在第一个图里坐的是1号位置，在第二个图里坐的是2号位置，在第三个图里坐的的3号位置，那么第四个图里应该坐4号位置了。
同样的道理，单独盯着其他每一种颜色看~宝贝们，你们都会了吗？6月21日第10题详解：此题选A.这题我相信很多宝宝都选对了~我们观察的方法可以是横着看，也可以是竖着看~不管横竖，变化规律是一样的那我们一起竖着看吧~从上到下，竖着的3条，变成竖着的2条，最后是竖着的1条~如果横着看，你会看吗？你发现了什么规律呢？来说说你的想法吧~6月23日 第11题详解：此题选A.这题是找规律中的常见类型，合并与拆分。
我们可以横着看，也可以竖着看。
如果竖着观察，你会发现前两排合起来就拼成了第三排的图形~同样，横着看，也是前两个图拼起来，变成了第三个图。
6月23日 第12题详解：此题选B.如果上一题会做的宝宝，我相信这一题也没有问题~这题我们同样有两种观察的方法：横着看和竖着看。
如果是横着看，你会发现第3个图是前面两个合起来的。
如果是竖着看，你会发现第1行和第3行拼起来变成了第2行的图，所以要知道第3行的图，就可以用第2行的图减去第1行的图，也就是我们之前有提到过的拆分哦，就是把一个图拆成两个。
6月24日 第13题详解：此题选E.嗯~这题还是合并和拆分。
同样，可以竖着看，也可以横着看。
如果竖着看，你会发现第2个和第3个图形拼成了第1个图形。
其实，拼成的那个图形可以是在第1个，可以是第2个，也可以是第3个~这三种情况，我们都碰到过咯~如果横着看，稍微有点点复杂，第2个和第3个拼成了第1个，不过，你在拼的时候，要注意了第3个图形宝宝是站在了左边，第2个图形宝宝是站在了右边。
现在要你找第3个图形宝宝，你就要看拼成图形左边的部分是谁，哈哈，你发现它了吗？6月25日 第14题详解：此题选C.看到五颜六色的图形，宝宝们马上就要想到颜色的变化~嗯~在找规律的时候，颜色和形状是两个很重要的观察点。
先观察形状，你会发现每一行都有减号、加号、点，那么第3行也应该有这三样小东西，它还缺减号，所以排除了D.除了头顶上的加减点，每一行下面部分都有一个图形，而且都是一样的，第1行全是长方形，第2行全是圆形，第三行应该全是正方形，所以空白处应该是正方，这时只剩下A和C了。
接着观察颜色，看上面部分的颜色，你会发现减号总是蓝色~~正方形是黑色，因为第1行三个长方形占了黑红蓝三种颜色，第2行圆形也是用了这三种颜色，所以第3行的正方形也要占三种颜色，已经有了红蓝，就缺黑色，所以答案是C 。
这题中，由于A和C的区别在上面的减号，正方形都是黑色，所以考试的时候可以不考虑正方形的颜色，但我们宝宝现在练手的时候，还是要明白为什么正方形是黑色哟~你能说清其中的道理吗？6月26日 第15题详解：此题选A.这题你会发现图形的形状没有变化，都是圆、方、点~它们只有位置变化~我们盯着一个图形看，先看蓝色的圆形，你会发现它顺时针走，所以最后应该在左边，只有ACD符合。
再盯着一个图形看，看黑色的圆，它也是顺时针变化，所以最后在最上面。
所以选A。
6月27日 第16题详解：此题选E.这题和我们前面的题是一个类型。
图形形状没有变化、颜色也没有变化，只是位置发生了改变。
我们的方法就是一个图形一个图形的看~好，宝贝们，你们已经知道怎么做了吧？先看黄色的小方块，它从左下角，走到了顶上，再到右下角，那么接下来又回到左下角。
同样的道理，黑色十字架从顶上到了右下角，再到左下角，那么接下来它也回到自己原来的地方顶上。
所以答案和第一个图形是一模一样的~~6月28日 第17题详解：此题选C.这题和我们这几天碰到的题是一个类型~方法也是一样的，就是一个图形一个图形的~先盯着蓝色的圆形看，你会发现它是顺时针转，所以只能是ACD.然后盯着黄色的三角看，诶，三角形不是顺时针转，也不是逆时针转呢，它的小脑袋先上，再下，再上，那么接着就应该是朝下了。
小朋友们，你们发现这个陷阱了吗？其实，还有一个小陷阱，如果你盯着黑色小圆点看，你会发现它是逆时针走的，对吧？所以，这题我们小朋友不能整个图形一起看噢，要盯着一个图形一个图形的找它们的规律~6月29日第18题详解：此题选E.亲爱的小宝贝们~这题使我们旋转题里头最最最难的一种噢~~因为这回不光光是图形宝宝的位置发生了变化，而且它们自己身体的上下左右也在转。
（公转+自转）先来找每个图形宝宝要住到哪个格子里，很快你会发现其实它们都是顺时针转，而且答案里每个格子里的图形是一样的~那我们就不用再管啦~接着来看每个格子里的图形该长成什么样子~如果你盯着黑球球，你会发现它的脑袋先在上面，接着在右边，接着在下面，还有哪一边没有去过？对啦，就是左边~答案里所有的黑球球脑袋都是朝左。
同样的道理，所有答案里的等号都一模一样，所以不用考虑~那么我们再盯着小三角，你会发现它的尖尖头先朝下，接着朝右，朝下，那么应该要朝左了，对吧？所以排除AB，答案在CDE里~~最后盯着直角角~你会发现它的尖尖角朝右上、右下、左下，所以接下来应朝左上~~所以答案为E。
ps：如果宝宝不明白方位，粑粑麻麻们可以画一个正方形，在正方形的四个角上标注1234~或者拿实物示范旋转~6月30日第19题详解：此题选B.哈哈，这题很简单吧~横着一排一排看，你会发现外面的正方形妈妈颜色肯定是蓝色，因为它前面的2个都是蓝色。
里面的正方形宝宝呢，是黑色的，但它的位置在发生变化，它是从左往右移动的，对吧？7月1日 第20题详解：此题选D.祖国的花朵们，这一题是19题的升级版噢，你做出来了吗？我们一起来观察吧~你会发现这些小方块们非常调皮，一直在移来移去，那它们移动的有什么规律呢？我们先顶着蓝色的看，你会发现它其实是每次往右挪动一格，对吧？哈哈，那你知道它接下来会去哪一格么？有的宝宝可能要说啦，蓝色方块要走出去了……既然没有房子可以住，那么蓝色方块只能乖乖的到左边第一个格子里，对吧？接着我们继续看单独的红色方块，因为单独一格的规律简单些。
红色是往右挪还是往左挪？对啦，往左边挪，哎呀，它也碰到了和蓝色方块一样的问题，没有房子可以住了，只好乖乖被挤到最后一格里。
7月2日 第21题详解：此题选D.亲爱的宝贝们，很抱歉这么晚给你们出题噢，因为朱老师白天在给一二年级的哥哥姐姐们上课，所以这段时间都只能晚上来见你们了。
你们正在梦乡中吧~好，我们一起来观察吧~我们很快发现每一行都有圆、三角、正方，所以肯定填的是三角~那么三角是什么颜色的呢？你会发现每行都有黄色、蓝色和白色，所以填的应该是黄色。
这样就只剩下BD。
接着看尖尖头，头上都有十字、T字和干字，那么缺的是干字，所以选D。
7月3日 第22题详解：此题选D.宝贝们，这题需要你们之前有接触过杨辉三角噢~如果你没有听说过，可能想起来会比较难一些。
这题是要你填最最顶上的，那么我们得根据下面的情况来找规律，对吧？好，你先看最低下一排，右边的两个，他们俩拼起来变成了上面一个，右边的第2、3个拼成了上面第2个，第3、4拼成了上面第3个，这里你看，如果是两个图形都有的，那么就会消失，如果是只有一个人有，那么就会保留下来。
也就是说，相同部分消失，不同部分留下来。
