Lyrics
Okay class
Today we are going to talk about categories and quantity
Categories are a group of items that look the same
And quantity is an amount or a number of something
On the table we have different color marbles
Some are green, some are red and some are blue
Let’s start by putting the same color into categories
Let’s start with green, now red, and now blue
Good! Now we have three different categories
Now let’s see how many marbles are in each group
Let’s start with green. 1, 2, 3 there are 3 green marbles
How about red? 1, 2, 3 there are 3 red marbles
Now what blue? 1, 2, 3 there are 3 blue marbles
Okay, you’re all done!
