Max Maths, Year 6, Practice, Review of rounding numbers and ordering decimals (2)

In the Max Maths Year 6 curriculum, students are tasked with practicing and reviewing their understanding of rounding numbers and ordering decimals. A key exercise involves arranging decimal numbers in order of size, from smallest to largest. To facilitate this, students are encouraged to use a place-value chart to compare the numbers. For instance, when presented with the decimals 5.82, 7.91, and 5.83, students would place each digit in its respective column: Ones, Tenths, and Hundredths. By examining the chart, it becomes apparent that 7.91 has the highest value in the Ones place, making it the largest number of the set. Comparing the other two, which are equal in the Ones and Tenths places, 5.83 is identified as the larger number due to its higher Hundredths value. Consequently, the correct order from smallest to greatest is: 5.82, 5.83, 7.91.

To further practice this skill, students are given additional sets of decimals to order using place-value tables. For example, they are asked to arrange decimals such as 8.56, 9.56, and 8.59, as well as 4.57, 4.55, and 1.99. The process involves placing each decimal in the place-value table and comparing the digits in the Ones, Tenths, and Hundredths columns to determine their relative sizes. By doing so, students can visually discern which decimals are smaller or larger and then write them in the correct ascending order. This exercise not only reinforces their understanding of decimal place values but also hones their ability to compare and sequence decimal numbers accurately.
