L3 Tenths on a Number Line and as Decimals

This Year 3 Fractions lesson on representing tenths as decimals on a number line supports pupils in making clear connections between fractions, decimals, and number lines . Fully aligned with the National Curriculum , this lesson builds fluency and understanding through visual models, discussion, and practical recording in books, making it ideal for Autumn term maths . The lesson begins by revisiting counting up and down in tenths and reinforcing that ten tenths are equal to one whole . Pupils are then introduced to decimals as a way of writing numbers that are not whole, with a clear focus on the decimal point and the meaning of the digit in the tenths place. Using animated slides, children explore how tenths are written as both fractions and decimals and how these values are positioned accurately on a number line. Practical activities allow pupils to choose tenths cards and represent their value on a number line, which they then record and label in their books using both fraction and decimal notation. Structured partner discussion and whole-class reasoning help pupils identify missing values and deepen their understanding of the relationship between tenths, decimals, and position on a number line. This resource includes: Fully planned lesson structure (starter, main activities, plenary) Animated teaching slides (best viewed in slideshow mode) Practical, worksheet-light activities suitable for book work Clear National Curriculum links Key questions, assessment opportunities, and common misconceptions Ideal for Year 3 teachers , this lesson strengthens pupils’ understanding of tenths while supporting accurate use of decimal notation and number lines.
