Round decimal numbers

The ArithmeKit 5 from Buzzard Publishing, part of the CanDoMaths series, presents a variety of exercises focused on rounding decimal numbers. The activities are designed to help Year 5 and Year 6 students enhance their understanding of rounding to the nearest tenth and whole number. For example, students are asked to round the number 3.55 to the nearest tenth, resulting in 3.6, and then to the nearest whole number, which would be 4. The exercise continues with a series of numbers such as 3.66, 3.77, and 3.88, each needing to be rounded accordingly. Additional tasks include rounding numbers like 3.44 and 3.33, and starting with a slightly different number, 3.54, students are encouraged to round a sequence including 3.54, 3.46, 3.47, and 3.48.

Further rounding activities involve matching various numbers to their correct rounded forms. For instance, 1.23 is rounded to one decimal place (1 dp) to become 1.2, while 1.55 rounded to 1 dp is shown as 1.6, which seems to be an error as it should correctly round to 1.6. Students are also prompted to round 1.32 to the nearest whole number, which is 1, and to round 1.25 to 1 dp, resulting in 1.3. The kit encourages critical thinking by asking students to create their own matching pairs problem involving rounding and to notice patterns in the rounding process. In another section, the pupils are challenged to solve problems with negative numbers and to use the digits 0-9 to complete statements around rounding, such as rounding 5.68 to the nearest whole number. The exercises are designed to be interactive and thought-provoking, helping students to understand the concept of rounding and its application in various contexts.
