This is reasoning activity where children are using the knowledge of times table and dividing 1 digit number by 10.
Ask, “When dividing a number by 10, how many equal parts is the number split into?”
They recognise that when using a place value chart, they move all of the digits one place to the right when dividing by 10.
Watch for:
Children may divide by 10 and put the decimal point in front of the number.
Children may move the digits in the wrong direction.

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: If a whole is divided into 10 equal parts, what is the value of each part? How can you represent the decimal How are decimals like fractions? using a model? How can you convert between tenths as fractions and tenths as decimals? How is 1/10 like 0.1? How is it different?
