| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

N.1.12 Classify the expression of an irrational number as exact or approximate
Year/Grade 9
Mathematics
20 students
30 minutes
This lesson aligns with the Canadian Mathematics Curriculum by focusing on the classification of numbers and supporting students in developing their understanding of irrational numbers.
| Step Number | Step Title | Length | Details |
|---|---|---|---|
| 1 | Introduction | 5 min | Begin with a brief review of rational numbers. Introduce irrational numbers and provide definitions. Present examples of each type. |
| 2 | Direct Instruction | 10 min | Explain how to classify irrational numbers as exact (like √2 or π) and approximate (like 1.414 or 3.14). Use examples on the whiteboard. |
| 3 | Guided Practice | 5 min | Distribute worksheets with examples of irrational numbers. Guide students through classifying the first few examples together. |
| 4 | Independent Practice | 5 min | Allow students to work on the remaining problems in pairs. Circulate the classroom to offer assistance as needed. |
| 5 | Review and Check | 3 min | Go over the answers as a class without asking students to present individually. Address any common misunderstandings. |
| 6 | Assignment | 2 min | Assign homework that includes additional classification problems and a couple of contextual problems involving irrational numbers. |
Check homework without class presentations. Assign students to classify a set of irrational numbers and apply the concepts learned in this lesson to real-world scenarios involving irrational numbers.
