评估问题 / Assessment
如果{{name}}看一张条形图，图里显示不同孩子上个月读了多少本书，{{name}}能算出总数、找出最多和最少之间的差，并按照类似“每格=2本书”的比例尺自己画一张图表吗？
If {{name}} looked at a bar chart showing how many books different children read last month, could they work out the total, find the difference between the most and least, and draw their own chart with a scale like "each square = 2 books"?
