Divide decimals using efficient methods
Maths Resource Description
The CanDoMaths ArithmeKit provides a structured approach to teaching efficient methods for dividing both whole numbers and decimals. The exercises encourage students to discern when to use mental calculations and when to apply written methods. For example, dividing 17.9 by 8 or 1.6 by 40 are tasks that could challenge students to decide the most efficient strategy. The kit prompts learners to write additional division calculations and determine the appropriate method for each, enhancing their mathematical reasoning and problem-solving skills.
Further exercises focus on dividing decimals, where students are tasked to calculate examples like 12.9 ÷ 3 or 21.6 ÷ 3, using either a written method or mental calculations with jottings. The goal is to identify which method is most efficient and to justify their choices. The ArithmeKit also includes problems that address misconceptions, such as whether dividing a decimal by a one or two-digit number always results in a decimal outcome. In addition, the resource provides practice in problem-solving with negative numbers, ordering large numbers, and rounding to required accuracy, all aimed at enhancing students' arithmetic proficiency.
