## Lesson Plan

### Introduction

In this lesson, students will learn to use Python math operators such as addition, subtraction, and division. Additionally, students will practice writing mathematical expressions throughout the modules.

### Vocabulary

• Operator: A symbol that modifies or combines values. For example, + and - are operators that add or subtract values.
• Expression: A sequence of values or variables connected by operators. For example, the expression b - a + 1 subtracts two variables and then adds the value 1.
• Binary Operator: An operator that only combines two values. Most of the operators that are commonly used in mathematical expressions like / and * are binary operators as the operation only involves the number before and after the operator.
• Modulus: The modulus operator is a binary operator that divides the first number by the second number and returns the remainder from that division operation. If the second number is a factor of the first number, the modulus operator will return 0.
• Incrementing: In programming, incrementing is the process of replacing a variable with the result of an operation and itself that increases the value stored in the variable. For example, x = x + 1 increments the value stored in x by 1.
• Decrementing: In programming, decrementing is the process of replacing a variable with the result of an operation and itself that decreases the value stored in the variable. For example, x = x/2 decrements the value stored in x by half of itself.

### Objectives

Students will...
• Write and apply mathematical expressions
• Apply coding concepts to convert integers to floats
• Use the exponent and modulus operators
• Increment and decrement values stored in variables
• Simulate real world mathematical equations with Python

### Warm-Up(5 minutes)

Ask students to solve the following:
1. 10 + 15 - 1 = ?
2. 4 / 2 = ?
3. 5 * 10 / 2 = ?
4. (2 + 2) * 10 / 5 = ?

1. 24
2. 2
3. 25
4. 8

### Activities(35 minutes)

Facilitate as students complete the Math Operators modules on their own:
• Students will read a short document that explains the addition and subtraction operator in Python.
• Optional: Before students select the “play” button, ask them to write down what they think the code will output.
• Do students need help with the “100th Birthday” puzzle? Give a hint: Tell them use the code listed above as a reference.
2. Multiplication and Division (Tutorial)
• Students will read a short document that explains the multiplication and division operator in Python.
• Optional: Ask students, “What is a binary operator?” (An operator that combines two values)
• Optional: Before students select the “play” button, ask them to write down what they think the code will output.
• Do students need help with the “Distance, rate, and time” puzzle? Give a hint: Tell students that they will need to divide by 60.
• Do students need help with the “Troll call” puzzle? Give a hint: Tell students that a troll’s name is “tr” concatenated with “ol” repeated “age” times.
3. Floats (Tutorial)
• In this module, students will expand on what they learned in the previous lesson about floats.
• Check that students are using floats in their puzzle solution.
4. Float Function (Tutorial)
• Students will read a short document that explains the float function, which returns its argument as a floating point number.
• Are students struggling with the puzzle? Tell students that they will need to convert values between decimal and integer representations. Optional: Tell students to include this in their code: str(int(applicants * percentage / 100.0))
5. Exponents (Tutorial)
• In this module, students will learn about exponents and the exponent operator (**).
• Students who are not strong at math are likely to struggle with the “Volume versus surface area” puzzle, so encourage students to brainstorm possible solutions with a partner.
6. Modulus (Tutorial)
• In this module, students are introduced to the modulus operator (%), which returns the remainder after dividing the number on the left by the number on the right.
• Optional: Before students select the “play” button, ask them to write down what they think the code will output.
• Are students struggling with the “Variable precision” puzzle? Tell them to use the code in the examples above as a reference.
7. Order of Operations (Tutorial)
• In this module, students will read a short document that reviews the order of operations.
• Optional: Before students select the “play” button, ask them to write down what they think the code will output.
8. Increment and Decrement (Tutorial)
• Students are introduced to incrementing and decrementing.
• Optional: Before students select the “play” button for the incrementing and decrementing examples, ask them to write down what they think the code will output.
• Say, “When a variable is replaced by a smaller value, the process is called ‘decrementing.’” Emphasize that its previous value is decreasing.
• This module does not contain puzzles.
9. More on Increment and Decrement (Tutorial)
• In this module, students will learn how to use incrementing and decrementing with other operators.
• The puzzle solutions in this module requires students to write multiple lines of code, so encourage them to work together as they solve the puzzles.
10. Fibonacci Sequence (Tutorial)
• This module introduces students to Fibonacci numbers and the golden ratio.
• Optional: Do a quick Google Images search of “golden ratio in nature” and show your students how mathematically beautiful nature can be!
• Are students are struggling with the puzzle? Give a hint: Tell them to include 7 additional variables to solve the puzzle.
11. Quiz
• In this quiz, students will solve 3 different math operators puzzles.
• In each problem, students will need to correctly apply math operators to produce the expected result.

### Discussion Questions/Follow-Up Activities(20 minutes)

• Ask students what they learned about using math operators in Python.
• Who can give an example of a math operator and explain how they applied it in today’s lesson?
• Have students create their own math operator problems and test it out using Python.
