How many?
Basics on the topic How many?
Learn to Count – Introduction
We learn to use 1:1 correspondence to count and answer the question “how many?”. Let’s learn how to count to answer how many with the following explanation.
When we ask “how many?”, we want to know the number, or amount, of something. Another way to ask this is ”how much?” or ”what's the total?”. To find out how many things there are, it is important to count each item carefully until the last one is reached. Objects can be shown neatly in a line, in a grid (array), or in a circle. But other times, items can be shown scattered all over. Whichever way objects are shown, it is critical to take your time while counting!
Learn to Count – Example
Your parents’ old keyboard is missing some keys. Luckily, we have a box in front of us with some spare keys. To figure out ‘how many’ keys there are in this box, we need to do the following:
- First, pick a place to start counting. The top left corner is a good place to start.
- Then, count aloud and mark off each item! This way, nothing gets skipped.
- Keep going until everything has been counted! Here there are one, two, three, four, five, six keys!
Since we stopped at six, this is how many keys there are. How many keys does the box contain? six!
