Model making, drawing and writing decimal numbers, showing that the decimal point is used to separate whole numbers from decimals.

Children look at a variety of representations of tenths as decimals, up to the value of 1 whole.

This leads to adding the tenths column to a place value chart for children to see how tenths fit with the rest of the number system and to understand the need for the decimal point.

Children may forget to include the decimal point.

If the number of tenths reaches 10, children may call this “zero point ten” and write 0.10 rather than exchanging for 1 one.

Children may confuse the words “tens” and “tenths”.

Questions to help with understaning the topic:
