已经做好的东西都要重做吗？

不用。继续像现在这样生成练习单、测验和教案。新作品可以挂在课上。旧文件可以先放在资料库，等你再挂上去。

这是聊天机器人吗？

不是。你选课、选要做什么，然后得到可打印材料。你不发布，它就不会发布。

适合我的学科和年级吗？

适合。数学、科学、语文等，从小学到高中。可以从班级开始，也可以直接做某个练习单主题。

什么时候扣费？

年付今天扣 135 美元。月付今天扣 19.99 美元。随时可取消。五分钟后你就有一节课——这个周末可以放松。

能打印并分享给学生吗？

每份资料都可下载 PDF。也可以发分享链接。答案只留在你这边。

Porosheets 是 MagicSchool AI 在练习单和教案上的替代吗？

是。MagicSchool 是一大套教师工具。Porosheets 是 AI 练习单生成器，也能做测验、教案和幻灯片，并挂在你要上的那节课上。

和 Canva 有什么不同？

Canva 做设计。Porosheets 写题目和教案，并把文件存在那节课上。海报继续用 Canva。练习单用 Porosheets。

Worked example

Lily has a pizza that is cut into 8 equal slices. She eats 3 slices. What fraction of the pizza does she have left?

Step 1: Determine how many slices are left. Total slices - slices eaten = 8 - 3 = 5 slices left.
Step 2: Write this as a fraction of the whole pizza. The fraction left is $\frac{5}{8}$ .

Warm-up

Sam has a chocolate bar divided into 4 equal parts. If he eats 1 part, what fraction of the chocolate bar is left?

If Maria has 10 apples and gives away 2 to her friend, what fraction of the apples does she have left?

What is $\frac{1}{2} + \frac{1}{4}$ ?

Practice

Carter baked a pie and cut it into 6 slices. If he ate 2 slices, what fraction of the pie is left?

Emma has 3/4 of a yard of ribbon. She uses 1/4 yard for a project. What fraction of the ribbon does she have left?

A recipe requires $\frac{2}{3}$ cup of sugar. If you only add $\frac{1}{3}$ cup, what fraction of the sugar is still needed?

A tank is $\frac{5}{6}$ full of water. If $\frac{1}{2}$ of it is used for watering plants, how much of the tank is left full? (Hint: subtract fractions)

Challenge

A farmer harvested $\frac{3}{5}$ of his crops. If he sold $\frac{1}{5}$ of what he harvested, what fraction of the crops does he still have?

If a car's gas tank can hold 1 full tank and it's currently filled to $\frac{7}{10}$ , how much more gas is needed to fill the tank? (Explore how to subtract fractions)

把周日要回来的老师

“周日晚上大概 40 分钟就把一周的课备完了，然后就干坐着。我反复打开看板检查，总觉得肯定漏了什么。”

Maggie T.

三年级教师

“它做练习单，还顺带把答案做好。我的评价就这一句。”

Dave R.

八年级科学

“学区推过来的 AI 工具我都试过，每次都默默回去用自己的老文件。这个留下来了，主要是因为东西直接落在那节课上，而不是掉进一个我再也不会打开的下载文件夹。”

Priya S.

高中数学

“我可以把同一份练习单用西班牙语或阿拉伯语发给刚来的学生——同一节课，同样的题。以前这要花掉我每个班整整一节备课时间。”

Carmen L.

ESL 专职教师

“我不是搞技术的人。我的整套系统就是一个活页夹，我还挺喜欢那个活页夹。这是第一个真的比活页夹快的东西。”

Rob W.

六年级教师，教龄 14 年

“带我的老教师说，别什么都从零开始做，不然撑不到十月就垮了。她说对了，我就是这么停下来的。”

Jasmine H.

七年级英语，入职第一年

“寒假后我让组里六位老师用它，做好了被抱怨的准备。结果组里最守旧的两位现在用得最勤。”

Tom B.

历史教研组长

“对我来说，简单版和提高版才是关键。我班上孩子的阅读水平分三档，现在大家拿到的都是“同一份”练习单，没人觉得自己被区别对待。”

Aisha M.

四年级教师

“早上六点接到电话说儿子病了。出门看医生之前，我用手机把两天的代课计划都排好了。真没夸张。”

Greg P.

初中数学

“说实话，题目质量比我预想的好。十道里我大概还会改一道，但那是润色，不是从头写。”

Nicole F.

高中生物

“这是我唯一自掏腰包订阅、而且一次都没想过退订的东西。”

Sam K.

五年级教师

“周五下午 3:40 走出学校，周一的课已经备好了。教书九年头一回。”
