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

In the "Max Maths, Year 6, Learn together" series, students are invited to practice their skills in rounding decimals and comparing decimal numbers. The first exercise focuses on rounding decimals to the nearest whole number. Students are presented with a series of decimal values such as 15.49, 8.09, and 99.99, and are tasked with determining what each would be when rounded to the closest whole number. This exercise is designed to reinforce their understanding of the rounding process and to help them recognise when a decimal is closer to the higher or lower whole number.

The second exercise requires students to round decimals to one decimal place. Decimals such as 15.49, 13.79, and 99.89 must be rounded to the nearest tenth, which further hones their ability to evaluate the importance of the digit in the hundredths place when rounding. In the section on comparing and ordering decimals, students are taught a systematic approach to determine which of two decimal numbers is greater. For example, when comparing 12.31 and 12.33, students are instructed to check each digit starting from the leftmost digit, moving through whole numbers and tenths, until they reach the differing hundredths place. Through this method, they conclude that 12.31 is less than 12.33, as 1 hundredth is less than 3 hundredths, making 12.33 the greater number. This step-by-step process is crucial for students to understand the value of each digit in a decimal and to compare decimal numbers accurately.
