Frequently Asked Questions
What is a tally mark and how do we draw it?
Tally marks are vertical lines used to count things. We draw four straight lines and cross the fifth line diagonally across them to make a bundle of five.
How do we read a pictograph where one picture equals many items?
Always check the key or scale of the pictograph first to know how many items a single picture represents, then multiply that number by the count of pictures.
Why is data handling taught in a chapter about a clean village?
It helps us record and compare useful information, such as how much plastic or organic waste is collected in different parts of the village to keep it clean.
