Find the difference between two numbers

The ArithmeKit 213 from CanDoMaths ArithmeKit provides a comprehensive set of exercises designed to enhance students' ability to find the difference between two numbers. The kit includes a variety of tasks, such as identifying missing elements in a sequence, creating matching pairs problems, and solving subtraction calculations. Students are encouraged to notice patterns and use these to devise their own problems, reinforcing their understanding of numerical differences. The exercises also challenge learners to list pairs of single-digit and teen numbers that have a difference of two and to represent these pairs in calculation form.

Another interesting aspect of the ArithmeKit 213 is the exploration of mathematical statements, such as whether the difference between two odd numbers is always even. Students are tasked with finding examples to prove or disprove this assertion. They are also prompted to solve problems with missing digits, ensuring that the final calculations are correct. This not only tests their subtraction skills but also their ability to reason and use logic. The kit includes a variety of subtraction problems with different levels of difficulty, such as 35 - 19 = 16 and 86 - 48 = 38, among others. These exercises are designed to help students develop fluency in finding differences and understanding the properties of numbers.
