How do we draw tally marks for the number 7?
You draw 4 vertical lines and cross them with the 5th slanted line to make a group of 5, then draw 2 more vertical lines beside it (5 + 2 = 7).
What is the use of a key in a pictograph?
The key tells us the value of each picture. For example, if one candy picture stands for 5 candies, we must multiply the total number of candy pictures by 5.
Why do we need to organize data?
Organizing data helps us read and understand information quickly without getting confused by a jumble of numbers.
