Children learn to:
Count ordinal numbers.
Show the molds and the bucket to the kid: “Look, the molds are small and the bucket is big!”
Pour sand into the bucket. When it is filled, you will be surprised: “That's how much sand! A whole bucket!”
Pour out all the sand from the bucket: “This is a big pile of sand! There is a lot of sand in it! ” Tell your child to do the same with the mold and mention the result: “And this is a small pile of sand! There is little sand in it! ”
The second task:
Tell the kid: “Let's find out how many sand molds are needed to fill up the bucket?”
Pour sand into the bucket with the molds and count with the child: “One, two, three!..
That's how many sand molds fit in the bucket! ”
The kid can fill the bucket himself, and at the same time you keep counting: “One, two, three sand molds! .. A whole bucket!”
