Lesson details

Key learning points

Tenths can label parts of a whole divided into ten equal parts.
Tenths can be positions on a numberline between whole numbers.
Tenths can be recorded as fractions and decimals on a number line.

Keywords

Tenth - A tenth is the name you give to one part of ten equal parts.
Decimal number - A decimal number has a decimal point followed by digits that show the fractional part.
Fraction - A fraction shows us how many equal parts in a whole.
Mixed number - A number which combines both a whole number and a fraction is known as a mixed number.

Common misconception

Pupils write whole numbers as tenths incorrectly, for example as eight tenths not eighty tenths.

Reiterate that ten tenths are equal to one whole so twenty tenths are equal to two wholes. Continue this to build generalisation.

Ensure children are able to generalise that a whole between any two consecutive numbers can be divided into ten equal parts making links between a 0-1 number line and any other number line with two consecutive numbers.
