L.C. To be able to recognise and write decimal equivalents of any number of tenths.
Look at the 2 squares and their shaded parts.
We know that 1 square shaded fully in pink is 1. It means this is 1 whole.
What about the other square?
Does it also represent 1 whole?
How much of it is shaded?
What is the number that can represent the parts shaded in pink?
Look at the square carefully.
How many parts is the square divided into?
How many parts are shaded in pink?
What do we call 2 parts out of 10 parts?
How do we read it?
So, how do write 1 part?
How do we read it?
There is another way of saying 1⁄10 and that is using a decimal.
We can write 1⁄10 as 0.1.
The dot is the decimal point.
1⁄10 is read as 1 tenth and 0.1 is also read as 1 tenth.
So we know that 1⁄10 = 0.1 = 1 tenth.
How do we write 2⁄10 as a decimal?
Compare 0.1 and 1.
Which is the larger number?
How do we know?
When 1 is divided into 10 parts, each part is 0.1.
So we know that 1 must be larger than 0.1.
We also know that 1 is 10 times bigger than 0.1.
How many 0.1 make 1?
