Authority is not new to mathematical class! One day mathematical class, can be to be different from really general ah!
大家对数学课都不陌生吧！有一天的数学课，可真是非同一般啊！
That day morning, the mathematical class on us is view composition examine ichnography of the our campus, campus that make.
那天上午，我们上的数学课是观察我们的校园、制作校园平面图。
In group later, the main task of our group is to circle outside school to walk along circuit, the quantity gives the degree of the length of every edge and every horn, draw school plan next.
分组之后，我们组的主要任务是绕校外走一圈，量出每条边的长度和每个角的度数，然后画出学校平面图。
The pen on the belt and paper come to the playground, we are in of the group leader guide next orderly ground to walk out of a school gate. The first edge is from rightward of school gate mouth the first corner is in, it is through measuring length 15. 64 meters, again right-hand rotation (quoin) 78 degrees, go before 42. 69 meters again right-hand rotation 46 degrees...
带上笔和纸来到操场，我们在组长的带领下有序地走出校门。第一条边就是从校门口向右的第一个转角处，通过测量长度为15。64米，再右转（外角）78度，前行42。69米再右转46度……
I take out a pen to draw sketch on paper, record these data on corresponding line segment and angle one by one.
我拿出笔在纸上画草图，把这些数据一一记录在相应的线段和角度上。
All the way, we are very careful very happy also, the feeling had to the school further knew. Take place of the 3rd corner, our ongoing footstep was given to hold off by ground of an oily cauliflower. Oily cauliflower leaves very flourishly. How should we pass here and to how should we pass here and measure edge part come out? For not cole of lay a finger on is beautiful, we crouch next bodies hard, each shrinks the body into mice kind, stick close enclosure to be passed slowly, measure carefully, record...
一路上，我们都十分小心也很开心，感觉对学校有了更进一步的认识了。走到第三个拐角处，我们前进的脚步被一片油菜花地给挡住了。油菜花开得非常茂盛。我们该如何通过此地并把边角测量出来？为了不触碰油菜花，我们努力蹲下身子，个个把身子缩成老鼠般，贴紧围墙慢慢通过，并小心测量、记录……
All the way, still stick on our body full a lot of dark green ear. Nevertheless, we are outstanding still finished the job -- circled school periphery to walk along circuit, measure the sketch that give all sorts of data and has drawn the school.
一路上，我们身上还粘满了许多苍耳。尽管如此，我们还是出色完成了任务——绕学校外围走了一圈，测量出各种数据并画好了学校的草图。
To draw sketch a few more accurately, we still combine other group to draw good campus sketch, below the teacher's help, according to certain proportion, finished relatively beautiful pursue with exact campus position.
为了把草图画得更精确一些，我们还结合其他小组画好的校园草图，在老师的帮助下，按照一定的比例，完成了一个较为美观和精确的校园布局图。
In 4 groups, the picture that our group paints, data is relatively accurate, campus board piece added different color again, be judged to be first prize so.
四个小组中，我们组画的图，数据相对精确，校园板块又增添了不同颜色，所以被评为一等奖。
I like such mathematical course very much. Such class than ever mathematical subject is much more interesting!
我好喜欢这样的数学课。这样的课比平常的数学课有趣多了！
After expecting such many somes of activity class!
期待以后多一些这样的活动课！
