This here represents 1 unit. Lets chop it up into 10 smaller pieces Next Home

Each smaller piece is 1/10 the size (10 smaller pieces fit in to the larger piece) Next Home

We call these pieces TENTHS Next Home

When we write a decimal, we write the whole number before the decimal point and the tenths after the decimal point. For example: is in the tenth column- 3 tenths 4 is in the tenth column- 4 tenths Next Home

Let’s create 0.3 and is 3 tenths, so we need 3 of the smaller tenth pieces Next Home

0.3 Next Home

0.4 is 4 tenths, so we need 4 of the smaller tenth pieces Next Home

0.4 Next Home

0.3 has 3 tenths, and 0.4 has 4 tenths So, which is the bigger decimal? Home

Ok, I will give you some more help. Home

These smaller pieces fit in to the tenth piece 10 times Next Home

We call these pieces HUNDREDTHS Hundredths are 10 times smaller than tenths Tenth Hundredth Next Home

In a decimal, the hundredths occupy the column after the tenths column (2 places after the decimal point is in the tenth column 6 is in the tenth column- 1 and 6 tenths 5 is in the hundredth column- 1 and 2 tenths and 5 hundredths Next Home

Let’s create 1.25 and 1.6 For 1.25, we need 1 whole unit, 2 tenths and 5 hundredths Next Home

Next Home

For 1.6, we need 1 whole units and 6 tenths Next Home

Next Home

So, which is the bigger decimal? Home

1. 7 Home Next

So, which is the bigger decimal? Home Next
