Understand the order of operations

Understanding the order of operations is crucial in mathematics to ensure accurate calculation results. The ArithmeKit 6.6, tailored for Year 6 students, presents a series of exercises that help reinforce this concept. Students are challenged to match calculations with their correct answers, taking into account the correct sequence of arithmetic operations. For example, they must recognize that in the expression "12 × 4 - 3", multiplication precedes subtraction, and in "12 ÷ 3 + 4", division comes before addition. The exercises also include creating matching pairs problems, where students can apply their understanding of the order of operations to determine equivalent expressions.

Further activities encourage students to solve problems with negative numbers and identify the value of each digit up to three decimal places. The students are presented with statements to complete, using each digit from 0 to 9 once, which requires a deep understanding of the order in which they should perform operations. The concept that multiplication and division should be carried out before addition and subtraction is reinforced through a variety of problems. For instance, they are asked to convince a character named Colin that "15 - 4 + 2" is not the same as "15 - 6", and that "18 ÷ 3 × 2" does not equal 3. These exercises help clarify common misconceptions and solidify the correct application of the order of operations in arithmetic.
