Encourage students to think of division as a fair way to distribute items and to understand its importance in daily life. Provide practice problems where students can apply their understanding of dividing by 9.

Understanding Division: Divide by 9 – Division: Splitting into equal parts – Division as ‘fair sharing’ – If 9 friends share 63 stickers, how many does each get? – Opposite of multiplication – If 3 x 9 = 27, then 27 ÷ 9 = 3 – Practice with dividing by 9 – Let’s divide 81 by 9 together on the board | This slide introduces the concept of division to third-grade students by relating it to the idea of splitting things into equal parts or groups, which they may already understand from sharing equally among friends. Emphasize that division is a way to ensure everyone gets the same amount, hence ‘fair sharing’. Draw the connection between division and multiplication by showing that they are inverse operations. Use simple examples like sharing stickers among friends to make it relatable. Finally, engage the class with a practical example of dividing by 9, such as dividing 81 into 9 equal groups, to solidify their understanding. Encourage students to use objects like counters or drawings to visualize the division process.

Dividing by 9 – Understanding division by 9 – Splitting into 9 equal groups Dividing something into 9 same-sized parts. – Example with cookies 18 cookies ÷ 9 groups = 2 cookies/group – Practice dividing by 9 Try dividing different numbers by 9. | This slide introduces the concept of division by 9, aiming to help third-grade students understand how to evenly distribute items into 9 groups. Start by explaining that division is a way of sharing things equally. Use the cookie example to visually show how 18 cookies can be divided into 9 equal groups, resulting in 2 cookies per group. Encourage students to think of division as the opposite of multiplication. Provide additional examples and have students practice with different numbers to solidify their understanding. Ensure that students are comfortable with the concept before moving on to more complex division problems.

Patterns in Dividing by 9 – Discover patterns with 9 – 9 has unique patterns, like adding digits equals 9 – Use 9-times table for division – If you know 9 x 9 = 81, then 81 ÷ 9 = 9 – Practice with examples – Try 81 ÷ 9, 72 ÷ 9, and 63 ÷ 9 – Understand division by 9 | This slide introduces students to the concept of division by 9 by exploring patterns associated with the number 9. Encourage students to use their knowledge of the 9-times multiplication table to assist with division. For example, if they know 9 x 9 equals 81, then dividing 81 by 9 will result in 9. Provide practice examples such as 81 ÷ 9, 72 ÷ 9, and 63 ÷ 9, and ask students to solve them using the patterns they’ve learned. Emphasize that understanding these patterns can make division easier and more intuitive. As an activity, students can work on additional problems and identify the patterns they see when dividing by 9.

Let’s Practice Division by 9! – Interactive Example: 45 ÷ 9 – Let’s solve 45 ÷ 9 together as a class. – Group Practice: 54 ÷ 9 – Come to the board and we’ll solve 54 ÷ 9 as a team. – Individual Practice: 27 ÷ 9 – Try solving 27 ÷ 9 on your own whiteboard. – Share and Discuss Answers – We’ll review everyone’s answers and methods. | This slide is designed for an interactive class activity to practice division by 9. Start with a guided example of 45 ÷ 9, solving it step by step with the class. Then, invite students to the board to solve 54 ÷ 9 as a group to encourage collaboration. Next, have each student work individually on 27 ÷ 9 using mini whiteboards, which allows for quick and easy sharing of answers. Conclude the activity by discussing the different methods students used to find their answers, reinforcing the concept of division by 9. Make sure to provide praise and constructive feedback to boost confidence and understanding.

Division Tricks with 9 – Learn the ‘finger trick’ for dividing by 9 – Use your fingers to divide numbers by 9 easily – Relate 9’s multiplication to division – Multiplying by 9 is the reverse of dividing by 9 – Practice with examples – Try 45 ÷ 9 using the finger trick – Quick check: Understanding the concept – Can you explain how the finger trick works? | This slide introduces students to the ‘finger trick’ for dividing by 9, a fun and interactive way to understand division. It’s important to show the relationship between multiplication and division with 9, as understanding one helps with the other. Provide students with examples to practice the finger trick and ensure they can use it effectively. Encourage them to explain the trick in their own words to assess comprehension. The goal is for students to feel more comfortable with division by 9 and to have a handy tool to use when they do not have a calculator.

Real-Life Application of Division by 9 – Understanding division by 9 – Sharing equally among friends – If you have 9 pizzas and 3 friends, how many pizzas does each get? – Division in daily life – Division helps us split things evenly in our everyday activities. – Practice with real examples – Try dividing items like toys or stickers by 9 to see how it works. | This slide aims to show students the practical use of division by 9 in real-life scenarios. It’s important for students to grasp that division is not just a mathematical concept but a tool they can use to share things equally.
