Max Maths, Year 4, Learn together, Hundredths (2)

In a Year 4 mathematics lesson on understanding hundredths, students are presented with a square divided into 100 equal parts, where 26 of these parts are shaded. The task is to express this shaded fraction as a decimal. To make this concept accessible, the shaded parts are grouped by colour, with blue representing 20 parts and green representing 6 parts. This visual grouping aids in understanding that 20 out of 100 is equivalent to 2 tenths, which is written as 0.2 in decimal form, while 6 out of 100 is equivalent to 6 hundredths, written as 0.06.

By adding these two decimal values together, students learn that 0.2 (the blue part) plus 0.06 (the green part) equals 0.26. This demonstrates that 26 out of 100 parts of the square are coloured, which is expressed as zero point two six in decimal form. This lesson not only teaches the conversion of fractions to decimals but also reinforces the concept of place value and the addition of decimals. For further practice and consolidation of the concept, students are directed to complete exercises on workbook pages 158 to 160.
