Round numbers with 1 decimal place to the nearest whole number

The ArithmeKit 4 4 from Buzzard Publishing, part of the CanDoMaths series, is a comprehensive tool designed to enhance students' understanding of rounding numbers with one decimal place to the nearest whole number. The kit includes a variety of exercises that encourage learners to engage with numbers in a hands-on manner. For example, students are asked to plot numbers like 2.6, 3.6, 4.6, and 5.6 on a number line before rounding them, to help visualise the concept. The activity also extends to matching pairs games where students must find two numbers that round to the same whole number, such as 77.1 and 18, which both round to 18 when applying the rules of rounding.

Further exercises challenge students to fill in missing digits to make statements true, using all digits from 0 to 9 exactly once, promoting critical thinking and problem-solving skills. Additionally, the kit presents scenarios for students to explore the effects of rounding on the value of numbers. For instance, Coco's hypothesis that rounding a number with one decimal place to the nearest whole number always increases its value is a topic for investigation. Students must use their knowledge to prove or disprove such statements, demonstrating their understanding of rounding numbers like 26.7 to 27, or 134.1 to 134. These activities not only solidify the students' grasp of rounding but also encourage them to articulate their mathematical reasoning.
