and write the decimal numbers
based on shaded part of the
fraction cards shown. Teacher
explain to pupils that:
- shaded parts in fraction cards of
ones have no digit after the
decimal point.
Teacher: We read as one.
We write the decimal as 1.
- shaded parts in fraction cards of
tenths have one digit after the
decimal point.

6. Teacher: We read as one tenth
or zero point one.
We write the decimal as 0.1.
- shaded parts in fraction cards of
hundredths have two digits after
the decimal point.
Teacher: We read as one hundredth
or zero point zero one.
We write the decimal as 0.01.
- shaded parts in fraction cards of
thousandths have three digits
after the decimal point.
