Objects and Stuff
How many more players are on the green team? How much more ice cream can you eat?
4
Why are there fewer fish in the class aquarium today? How much less water does our aquarium have than the one in the office?
5
Objects are things we can count, such as books and bananas. Stuff is a word to describe such things as sand, water, and air. You can’t count stuff...unless you put it in a container.
6
We use words such as many, much, some, a lot, lots of, gobs, tons, and dozens to describe numbers of objects and quantities of stuff.
7
When you talk about quantities of objects, you simply use numbers. You say, “I have 32 marbles.”
8
When you talk about amounts of stuff that you can’t count such as sand, water, and air, you might say, “I have a lot of sand.”
9
Or, you can put the stuff in containers and then count how many containers. You might say, “I have two bowls of ice cream.”
10
How Many?
How Much?
11
Comparing Numbers of Objects and Amounts of Stuff How do you know which words to use when you compare quantities of pebbles or pudding, sisters or syrup, marshmallows or milk?
12
13
Many or Much?
When you compare things that you can count like children, you say, “How many more?” How many more girls are there than boys?
14
15
When you compare stuff that you can’t count like soup or salad, you say, “How much more?” How much more salad do you have than James?
16
17
Fewer or Less? Do you have fewer cookies than your classmate or do you have less cookies? Do you have fewer milk in your glass than your sister or do you have less milk?
18
19
The rule for fewer and less is simple: use fewer if you can count the things, use less if you can’t. Fewer pancakes, less syrup.
20
21
How many more or how much more? Fewer than or less than? Now, you are ready to compare the numbers of objects and quantities of stuff in your world.
22
Glossary amount (uh MOUNT) — how much of something there is container (kon TAIN er) — something to put things in, such as a box, can, or bowl quantities (kwant uh tees) — amounts or numbers of things syrup (SUR uhp) — a thick sweet liquid
