Title: Counting in 5s

Grade Level: 3rd Grade

Objective: - Students will be able to count forward and backward by 5s up to 100. - Students will be able to identify patterns in counting by 5s. - Students will be able to solve simple addition and subtraction problems involving counting by 5s.

Materials: - Counting by 5s chart or number line - Whiteboard or chart paper - Markers or colored pencils - Counting by 5s worksheets - Manipulatives (optional)

Procedure:

1. Introduction (5 minutes): - Begin the lesson by asking students if they know how to count by 5s. Allow a few students to share their knowledge. - Explain that counting by 5s is an important skill that can help us solve problems quickly and efficiently. - State the objective of the lesson: to learn how to count by 5s and use this skill to solve problems.

2. Counting by 5s Chart (10 minutes): - Display a counting by 5s chart or number line on the whiteboard or chart paper. - Start counting by 5s together as a class, emphasizing the pattern and repetition. - Have students take turns counting by 5s, going both forward and backward. - Encourage students to identify any patterns they notice while counting.

3. Guided Practice (15 minutes): - Distribute counting by 5s worksheets to each student. - Instruct students to complete the worksheets by filling in the missing numbers in the sequence. - Circulate the classroom to provide assistance and monitor progress. - After completing the worksheets, review the answers as a class, discussing any challenges or questions that arose.

4. Independent Practice (15 minutes): - Divide the class into pairs or small groups. - Provide each group with manipulatives (if available) or allow them to use their fingers to count by 5s. - Instruct students to take turns counting by 5s, starting from different numbers and going both forward and backward. - Encourage students to challenge each other by giving them numbers to start from or asking them to skip count by 5s from a given number.

5. Application (10 minutes): - Write a few simple addition and subtraction problems on the whiteboard or chart paper that involve counting by 5s. - Call on students to solve the problems using their counting by 5s skills. - Discuss the strategies used and encourage students to explain their thinking.

6. Conclusion (5 minutes): - Recap the main points of the lesson, emphasizing the importance of counting by 5s and how it can help solve problems efficiently. - Ask students to share any new insights or discoveries they made during the lesson. - Provide positive feedback and praise for their efforts and progress.

Extension Activity: - Challenge students to create their own counting by 5s puzzles or games to share with their classmates. - Have students practice counting by 5s in real-life scenarios, such as counting money or measuring objects in the classroom.
