Welcome
Counting and Comparing 🔢
Hi there! Today we play with counting and comparing.
When we count, we find out how many. One, two, three!
When we compare, we find out who has more, who has less, and when two groups are the same.
Grown-ups call this reading data. You call it fun! Let's go.
Count the Blocks
Let's Count 🧱
Picture three blocks in a row. Point at each one and say a number.
One... two... three!
Counting tells us how many. Now you try.
Who Has More?
More, Less, Same ⚖️
Now let's compare. Comparing means looking at two groups.
More means a bigger amount. Less means a smaller amount.
When both groups have the same amount, we say they are the same.
Picture two plates. One plate has 2 cookies. One plate has 5 cookies.
When They Are the Same
The Same 🟰
Sometimes two groups have the same amount.
Picture two cups. One cup has 3 buttons. The other cup also has 3 buttons.
Not more. Not less. They are the same!
A Fair Way to Compare
Comparing Fairly 🤝
When we compare, we want it to be fair.
Fair means we compare the right way. Two good tricks:
- Use the same size cups or cups. A big cup and a tiny cup is not fair!
- Line them up side by side. Then you can see which row is taller and has more.
Look at the picture. The blocks are lined up. The taller row has more. That is a fair way to see it!
Pictures Can Show How Many
A Picture Shows How Many 🖼️
Here is a secret. A picture can show how many, all at once!
Picture a row of 4 red apples and a row of 2 green apples, lined up.
You do not even have to count slowly. You can look and see the red row is longer. The red row has more!
That is how a picture helps us compare. Lining things up in rows makes it easy to see.
