Welcome to Division! – What is division? – Division means sharing things equally. – Today’s goal: Divide with arrays – Arrays help us divide numbers step by step. – Division in daily life – Use division to split snacks or share toys. – Practice makes perfect | This slide introduces the concept of division as a method of sharing things equally among a certain number of groups. The goal for today’s lesson is to understand how to divide 2-digit numbers by 1-digit numbers using arrays, which are visual tools that help break down the division process into manageable steps. Emphasize the practicality of division in everyday life, such as dividing snacks among friends or sharing toys equally. Encourage students to practice with different examples to become comfortable with the concept. Provide a variety of practice problems and use group activities to reinforce learning.

Understanding Division with Arrays – Division creates equal groups – Division splits things into smaller, equal parts – Division is reverse multiplication – If 3 x 4 = 12, then 12 ÷ 3 = 4 – Share 12 apples with 3 friends – Each friend gets an equal amount of apples – Visualize with arrays – Arrays show division as rows of equal groups | This slide introduces the concept of division to fourth graders by relating it to the idea of making equal groups, which is a more tangible approach for young learners. It’s crucial to emphasize that division is essentially the opposite of multiplication, a concept they are already familiar with. Use the example of sharing 12 apples among 3 friends to illustrate how division works in real life, ensuring that each friend gets an equal share. Introduce arrays as a visual tool to help students understand and organize their division problems. Arrays will show the divided items as rows, which can be counted to find the answer. Encourage students to draw their own arrays with different division problems to reinforce the concept.

Dividing with Arrays – Arrays organize objects – Think of arrays like a neat chocolate box – Rows represent division groups – Each row is a group you divide into – Example: 20 ÷ 4 as an array – 5 rows of 4 gives us 20, showing 20 ÷ 4 = 5 – Practice creating your own arrays | Arrays are a visual way to represent division problems by organizing items into rows and columns. Each row in an array corresponds to a group in the division process. For example, dividing 20 by 4 can be visualized as an array with 5 rows of 4 items each. This helps students understand that division is essentially grouping. Encourage students to draw their own arrays for different division problems to reinforce the concept. Provide additional examples like 15 ÷ 3 or 18 ÷ 2 and ask students to create arrays that represent these divisions. This will help solidify their understanding of arrays and division.

Step-by-Step Division Using Arrays – Start with a division problem – If we have 24 ÷ 3, what are the numbers to divide and the divisor? – Make an array for the divisor – Arrange 24 items into rows of 3 to form an array – Count rows for the quotient – How many rows do you have? That’s your answer! | This slide introduces students to the concept of using arrays to divide 2-digit numbers by 1-digit numbers. Begin by explaining the division problem and identifying the dividend and the divisor. Then, demonstrate how to create an array using the divisor as the number of items in each row. Use manipulatives or drawings to visually represent the array. Finally, guide students to count the number of rows to find the quotient, reinforcing the concept that division is essentially repeated subtraction. Provide several examples with different dividends and divisors to ensure understanding. Encourage students to try creating their own arrays with classroom materials or on paper as part of the activity.

Let’s Practice Division with Arrays! – Divide 24 by 3 using an array – Arrange 24 objects in 3 equal rows to see how many in each row – Divide 36 by 4 using an array – Arrange 36 objects in 4 equal rows to find the number per row – Partner up for array creation – Work together to understand arrays – Share your arrays with the class | This slide is designed for a class activity where students will apply their understanding of division using arrays. Start by demonstrating how to divide 24 by 3 with an array, arranging objects into 3 equal rows and counting how many are in each row. Repeat the process with 36 divided by 4. Encourage students to work in pairs to create their own arrays with classroom materials like counters or drawings. This collaborative effort helps students to visualize division and verify their answers. After the activity, have each pair share their arrays and explain their division process to the class. This reinforces their understanding and allows them to learn from each other’s strategies.

Dividing with Arrays: Challenging Examples – Divide 56 by 7 using an array – Arrange 56 objects into 7 equal groups. How many in each? – Divide 48 by 6 using an array – Arrange 48 objects into 6 equal groups. What’s the size of each group? – Discuss array setup with a classmate – Think about how you created groups and compare with a friend – Share your methods and answers | This slide presents two challenging examples for students to apply their understanding of division using arrays. For the first example, students should visualize 56 items and group them into 7 equal parts, then count how many items are in each group. The second example follows a similar process with 48 items divided into 6 groups. Encourage students to use drawings or physical objects to create their arrays. After attempting the problems individually, students will pair up to discuss their strategies and solutions, promoting collaborative learning. Finally, they will share their findings with the class to reinforce their understanding and learn from different approaches. Possible activities include using counters, drawing arrays on graph paper, or using interactive digital tools to create arrays.

Division Tips and Tricks – Use multiplication to divide – Remember, division is the opposite of multiplication! – Skip count to form arrays – Count by 2s, 5s, or 10s to make arrays faster. – Check work using multiplication – After dividing, multiply to see if you get the original number. – Practice with different numbers | This slide aims to provide students with helpful strategies for dividing 2-digit numbers by 1-digit numbers using arrays. Encourage students to use their knowledge of multiplication facts to assist with division, as understanding the inverse relationship between these operations is crucial. Introduce skip counting as a method to quickly create arrays that represent division problems. Emphasize the importance of checking their work by multiplying the quotient by the divisor to see if it equals the dividend. Provide various examples and encourage students to practice these tips with different numbers to build confidence and proficiency in division.

Class Activity: Array Division Art – Create art with division arrays – Each student receives paper and stickers – Use stickers for array division problems – Arrange stickers to show groups, like 18 ÷ 3 with 6 stickers in 3 rows – Display your division art in class | This activity combines creativity with math to help students visualize division. Provide each student with a large sheet of paper and a set of stickers. Instruct them to use the stickers to create arrays that visually represent division problems. For example, if the division problem is 18 ÷ 3, they should place stickers in rows to create three groups with six stickers in each group. This hands-on activity will help solidify the concept of division as making equal groups. After completing their arrays, students can add decorative elements to turn their math into art. Encourage students to explain their division problems and how they represented them with their arrays. Display the finished art pieces in the classroom to celebrate their understanding and creativity.
