Highlight the practicality of learning to divide by 12, such as understanding how many months are in a year or dividing items that commonly come in dozens. Encourage students to think of other examples where dividing by 12 might be useful in their daily lives.

Understanding Division: Divide by 12 – Division: Splitting into equal parts – Division is opposite of multiplication – Example: 12 ÷ 3 = 4 – If we have 12 apples and split them into 3 groups, each group has 4 apples. – Practice dividing numbers by 12 – Try with different numbers: 24 ÷ 12, 36 ÷ 12, etc. | This slide introduces the concept of division to third-grade students by explaining it as the process of splitting something into equal parts or groups. It’s important to clarify that division is the inverse operation of multiplication. Use everyday examples, like dividing a set of apples among friends, to make the concept relatable. The example provided uses simple numbers to illustrate the point. Encourage students to practice with multiples of 12 to reinforce the concept. Provide additional examples and practice problems to ensure students are comfortable with dividing by 12 before moving on to more complex division problems.

Dividing by 12: Sharing Equally – Understanding ‘a dozen’ – A dozen is 12 items, like eggs in a carton – Dividing means equal parts – To divide by 12 is to make 12 equal groups – Sharing 12 items equally – Imagine splitting 12 cookies with friends – Division by 12 in real life | This slide introduces the concept of division by 12, starting with the familiar term ‘a dozen’ to help students relate to the number 12. Emphasize that dividing by 12 means splitting something into 12 equal parts. Use relatable examples such as dividing 12 cookies among friends to illustrate the concept. Encourage students to think of other situations where they might need to divide by 12, like 12 months in a year or 12 hours on a clock, to show the practical application of this skill in everyday life.

Using Multiplication to Master Division by 12 – Know your 12 times table – Reverse multiplication for division – If 12 x 3 = 36, then reversing it helps find 36 ÷ 12 – 36 divided by 12 equals what? – Use what you know from multiplication to solve – Practice division with examples – We’ll work through examples as a class | This slide is aimed at helping third-grade students understand how multiplication and division are related, specifically when dividing by 12. Start by reviewing the 12 times table, as familiarity with it will make division by 12 much easier. Explain that division is essentially the reverse of multiplication. For example, if they know that 12 times 3 equals 36, then they can figure out that 36 divided by 12 equals 3. Practice this concept with several examples, encouraging students to use their multiplication knowledge to solve division problems. This will help reinforce their understanding and build confidence in their division skills.

Let’s Practice Dividing by 12 – Understand division by 12 – Visualize with objects or drawings – Use counters or draw pictures to see groups of 12 – Solve an example: 24 apples for 12 people – Each person gets 2 apples (24 ÷ 12 = 2) – Class activity: Work through problems | This slide is aimed at helping third-grade students practice the concept of division by using the number 12. Start by explaining that division is a way to share things equally. Use physical objects like counters or drawings on the board to help students visualize dividing a set of items into groups of 12. Walk through the example problem by showing that if you have 24 apples and want to divide them equally among 12 people, each person would receive 2 apples. Encourage students to participate by solving similar problems as a class activity. Provide guidance and ensure each student understands the process before moving on to individual practice.

Word Problems: Divide by 12 – Apply division in real life – How many dozens in a given number? – Read and solve together – We’ll work as a team on problems – Discuss solving strategies – Use drawings or grouping to divide – Practice with examples | This slide aims to help students understand the application of division in everyday contexts by dividing by 12, which is the number of items in a dozen. Start by explaining that division can be used to find out how many groups of a certain size we can make from a larger number. Present word problems that involve dividing by 12, such as dividing items into dozens. Work through these problems as a class, encouraging students to participate and think aloud. Discuss different strategies they can use, such as drawing pictures, using physical objects to group into sets of 12, or skip counting by 12s. Provide a variety of problems to practice and ensure to give feedback on their problem-solving approaches.

Division Games: Mastering Divide by 12 – Engage in a division game – Pair up for problem-solving – Work with a friend to solve problems like 24 ÷ 12 or 36 ÷ 12. – Use flashcards for practice – Flashcards help memorize division facts quickly. – Try a timed division challenge – Race against the clock to solve as many divide by 12 problems as you can! | This slide is designed to introduce interactive and fun division games to help third-grade students reinforce their understanding of dividing by 12. Encourage students to participate in a division game that can be played in the classroom. Pairing students allows them to collaborate and learn from each other while solving division problems. Using flashcards can make memorization of division facts a more engaging activity. Introducing a timed challenge adds an element of excitement and helps students improve their speed and accuracy. As a teacher, prepare a set of division by 12 flashcards, create or find a suitable division game, and set up a timed challenge that is appropriate for the students’ skill level. Offer guidance and support as they work through these activities.

Class Activity: Divide and Conquer! – Split into groups of 12 students – Each group gets 12 items to share – Make sure everyone gets an equal amount – Discuss the division of items – How did you divide the items among your group? – Understand sharing equally – This helps grasp the concept of division by 12 | This interactive class activity is designed to help students understand the concept of division by physically dividing objects among group members. By working in groups of 12, students can easily visualize the division process and the idea of equal shares. Provide a variety of items (e.g., counters, pencils, fruits) to keep the activity engaging. After the division, facilitate a discussion to allow students to explain their division strategy and to reinforce the concept of equal distribution. This hands-on experience is crucial for their understanding of division as sharing equally. Possible variations of the activity could include using different numbers of items or having students role-play as items to be divided.
