Provide clear examples and ensure that students understand the process of dividing larger numbers by smaller ones. Discuss the importance of division in daily life, making it relatable to the students’ experiences.

Quick Review: Division Basics – Understanding Division – Division is sharing or grouping equally – Dividing 1-digit numbers recap – Review of simple division without remainders – Key Vocabulary: Dividend, Divisor, Quotient, Remainder – Dividend: number being divided, Divisor: number you divide by, Quotient: result, Remainder: what’s left over – Applying division to 2-digit and 3-digit numbers | This slide is a quick refresher on the concept of division, aimed at preparing students for more complex problems involving 2-digit and 3-digit numbers. Start by explaining division as a method of sharing equally or grouping. Recap dividing 1-digit numbers to ensure foundational understanding. Introduce the vocabulary terms ‘dividend’, ‘divisor’, ‘quotient’, and ‘remainder’ with clear definitions and examples. Emphasize that these terms will be crucial when tackling larger numbers. Conclude by highlighting that the same principles apply when dividing larger numbers, and the upcoming lessons will build on this knowledge.

Dividing 2-Digit by 2-Digit Numbers – Example: 36 ÷ 12 – How many times does 12 fit into 36? – Step-by-Step Division – Divide, multiply, subtract, bring down – Practice Problem: 54 ÷ 18 – Work together to solve 54 ÷ 18 – Discuss Remainders – Sometimes division doesn’t divide evenly | This slide introduces students to the concept of dividing 2-digit numbers by 2-digit numbers. Start with a simple example, 36 divided by 12, to show that 12 fits into 36 exactly three times. Walk through the division process step-by-step: divide the first number by the second, multiply the divisor by the quotient, subtract from the dividend, and bring down the next digit if necessary. Then, engage the class with a practice problem, 54 divided by 18, and solve it together. Discuss what happens when numbers don’t divide evenly and introduce the concept of remainders. Encourage students to ask questions and provide guidance as needed. The goal is for students to understand the process and feel confident in tackling similar problems.

Dividing 3-Digit by 2-Digit Numbers – Example: 156 ÷ 13 – How to divide 156 by 13 step by step – Break down: Same steps, bigger numbers – Let’s solve together: 231 ÷ 21 – We’ll go through 231 ÷ 21 as a class – Practice makes perfect: Try more problems – I’ll provide more examples for you to practice | This slide introduces students to the concept of dividing larger numbers while using the same division steps they are familiar with. Start with a clear example, such as 156 divided by 13, and walk through the problem step by step. Emphasize that the process is the same as with smaller numbers, just with a few more steps. Then, engage the class with a practice problem, solving 231 divided by 21 together. Encourage participation and guide them through the process. Finally, provide additional problems for independent practice to reinforce the concept. Make sure to circulate around the room to offer help as students work through the problems.

Understanding Remainders in Division – Division doesn’t always divide evenly – Remainders explained – The number left over after division – Example: Divide 125 by 24 – 125 ÷ 24 equals 5 with a remainder of 5 – What to do with a remainder – Use in real-life situations or round as needed | When we divide numbers, sometimes they don’t fit perfectly into each other, and we’re left with a remainder. It’s important for students to understand that a remainder is the part of the dividend that is left over after division when the numbers don’t divide evenly. For example, when we divide 125 by 24, it goes into 125 five times with 5 left over. This remainder can be crucial in real-life situations, such as when dividing items among a group of people and determining how many items are left. Encourage students to think of situations where they might need to consider the remainder. Also, discuss when it might be appropriate to round the result to a whole number.

Division Mastery: Tips and Tricks – Use estimation to simplify division – Round numbers to nearest ten to estimate – Multiply to check division answers – After dividing, multiply quotient by divisor to see if you get the dividend – Mnemonics help remember division steps – Create catchy phrases to keep the division process steps in mind – Practice with different number sizes | This slide aims to equip students with strategies to tackle division problems involving 2-digit and 3-digit numbers. Estimation can make complex division problems more manageable by simplifying numbers to their nearest ten. Students should always check their work by using multiplication; if the product of the quotient and the divisor equals the dividend, the division is correct. Mnemonic devices are useful for remembering the sequence of steps in long division. Encourage students to practice these tips with numbers of varying sizes to build confidence and proficiency. Provide examples and have students create their own mnemonics as a class activity.

Let’s Practice Together: Group Division Challenge – Engage in a group division challenge – Solve division problems in pairs – Work together to divide numbers like 156 ÷ 12 – Discuss your methods and answers – How did you solve it? Did you use long division? – Share solutions with the class | This class activity is designed to promote collaborative learning and practice division skills. Divide the class into pairs and provide each pair with a set of division problems involving 2-digit and 3-digit numbers divided by 2-digit numbers. Encourage students to communicate and solve the problems together, using long division. After solving, each pair will discuss their methods and how they arrived at their answers. Then, select a few pairs to present their solutions and methods to the entire class. This will help students learn from each other and understand different approaches to solving division problems. Possible activities for different pairs could include dividing numbers with no remainders, with remainders, or even starting to explore division with decimals if they’re ready for a challenge.
