Starry, what have you done?

Why have you put so many fishes into this tank?

It’s very crowded.

And this tank has just a few fishes.

When we look at the two tank,Starry.

This tank has more fishes.

And in this tank the fishes are less as compare to that tank.

More fishes-less fishes.

But Starry, the tank with more fishes has less shells in it,one two shell. only two shells

Oh, and the tank with less fishes has more shells in it,one two three four shells.

More shells, Starry

less shells ,More shells,

even the water plants are different,Starry

this tank has more plants in it.

In this tank, the plants are much less.

More plants,less plants.

Starry, you are smart.

I forgot the oxygen bubbles.

This tank has more bubbles in it.

And this tank has less bubbles.

More bubbles-less bubbles.

Starry, there is another way to find out the different between more and less.

Look at this board.

On this side, there are 1-2-3-4-5 fish. On the other side, there are 1-2 fish

Now,let’s form 1 to 1 pair,1 fish to 1 fish

The second fish to the next fish

Now,  we still have three unpaired fish on this side.

So we say,more fish and less fish.

Now,here are some starfish.

We have 1-2-3-4 starfish on one side.

And 1-2-3-4 starfish in the other side.

Let make 1 to 1 pair Starry.

Look, there are no extra starfish.

The starfish on both sides are the same.

So we say “both sides have equal starfish”.

And here Starry are some shells.

1-2 shells and 1-2-3-4 shells

Let’s make the 1 to 1 pairs

We have to shells remaining on this side, Starry.

So we say, less shells,more shells.

Let’s do an activity together.

See, which side has more and which side has less objects.

1-2-3-4-5-6  frogs

1-2-3 frogs

This side that has 6 frogs Starry has more frogs

And this side with three has less frogs.

And now birds. 
1-2-3 birds,1-2 birds. 
More birds-less birds

Here we are some flowers, Starry. 
1-2-3-4-5 flowers,
1-2-3-4-5 flowers

Starry, here the number of flowers on both side is the same

And now, some butterflies.

1-2-3 butterflies.

1-2-3-4 butterflies.

Less butterflies-more butterflies.

So, Starry, you have now learned to identify more and less

More means a lot of objects

Less means   a few objects.
