Add 10 to a number

The ArithmeKit 1.16 from Buzzard Publishing's CanDoMaths series offers a practical exercise in adding ten to various numbers. Students are presented with pairs of numbers, where they must identify the pattern that the second number is always ten more than the first. This exercise encourages the development of mental arithmetic skills and reinforces the concept of place value, as students observe that when ten is added to a number, the ones digit remains unchanged. The kit includes a variety of tasks, such as filling in missing digits to complete the addition correctly, and challenges students to create their own number pairs that demonstrate the addition of ten.

In addition to pattern recognition, the ArithmeKit provides opportunities for students to test Colin's assertion that the ones digit stays the same when ten is added to a number. Through hands-on activities, students are tasked with disproving the misconception that adding ten to a number like 35 results in 36, emphasising the importance of understanding place value. The kit also includes exercises where students must use the digits 0 to 9 to solve addition problems uniquely, promoting critical thinking and problem-solving skills. The exercises range from simple additions, such as 4 + 10, to more complex ones involving larger numbers, ensuring that students at different levels of proficiency can engage with the material effectively.
