Year 4 Tenths as Decimals Foundation Reasoning activity

This is reasoning activity targeted at lower ability Year 4. The number line in this question is a visual resource to support the understanding of decimal numbers.

Before children attempt this worksheet, they should encounter, practice writing and reading decimal numbers and the decimal point, model making, drawing and showing that the decimal point is used to separate whole numbers from decimals in the main worksheet displayed on the website.

Children look at a variety of representations of tenths as decimals on the number line. This leads to representing the tenths in the bar models and finally in the place value charts.

The place value chart shows how tenths fit with the rest of the number system and to understand the need for the decimal point.

Watch for:

Children may forget to include the decimal point.

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

You might ask them:

"If a whole is split into 10 equal parts, then what is each part worth?

"If a whole is split into 10 equal parts, then what are the three parts worth?
