Lesson 15: Encryption and Decoding

Each letter is assigned a numerical value, which is then manipulated through a specific operation (e.g., adding a number, or "shifting" it) to create the encrypted message. The decoding process is the reverse, requiring a different operation to convert the number back to its original value.
addition and subtractionSC.4.PE.3.2, SC.4.CC.1.2,
SC.K12.CTR.5.1, MA.K12.MTR.7.1:		Decoding is an integrated application of subtraction.
To reverse the process, students must subtract the
same number from the encrypted letter's value.
Using the same example, to decode the shifted letter,
they would perform the operation of X-3 to get back to
the original letter.

Lesson 12 :Variables

This lesson using variables as a tool for counting and data collection, builds the automaticity needed to seamlessly integrate variables into their programming logic, laying the groundwork for more complex tasks like building counters and data trackers. 		additionSC.4.PE.1.2, SC.4.PE.2.1, SC.4.PE.3.1,
SC.K12.CTR.6.1		The concept of a counter, which is a core application of
a variable, implicitly relies on addition. The lesson
reinforces the idea that variables can hold a value and
that value can be changed, which, in the case of a
counter, is done through repeated addition.

Lesson 24: Data Practice

This lesson provides a foundational introduction to key terms.This lesson makes abstract statistical concepts tangible by connecting them to hands-on activities, reinforcing how math is used to make sense of the world around them. 		graphical representation, data, bar graphSC.4.PE.2.1, SC.4.PE.2.2, SC.4.CC.1.2,
SC.K12.CTR.6.1, MA.K12.MTR.2.1		The core class activity involves students creating a bar
graph to visually organize their collected data.
The lesson explicitly teaches that this is a form of
graphical representation used for analysis.

The lesson guides students to analyze their graphs to
draw conclusions and answer questions, using the
graph as evidence.

Lesson 16: Conditionals

Properties of Operations, Equality, and Inequality
This lesson provides a foundational understanding of equality and inequality by teaching students the concept of conditional logic. It frames programming as a series of decisions based on whether a given statement is true or false. 		equality and inequality, conditional logic, relational propertySC.4.PE.1.2, SC.K12.CTR.4.1,
MA.K12.MTR.5.1		The lesson explains the "if" part as the condition and the
"then" part as the action. This teaches the fundamental
structure of a conditional statement, which is a logical
pattern that can be used to control program flow based
on whether a condition is met or not.

Lesson 12: Variables

The lesson focuses on understanding that a variable is a named container for a value, and that its value can be changed. This understanding is crucial for students to eventually use variables within mathematical formulas in future lessons.

additionSC.4.PE.1.2, SC.4.PE.2.1, SC.4.PE.3.1,
SC.K12.CTR.6.1		The "School Lunch Dilemma" activity presents a scenario
where students would need to use variables in expressions
to solve a problem. For example, to find the total number of
students, they would mentally formulate an expression like
Total_Students = Pizza_Orders + Nugget_Orders + Sandwich_Orders.
This demonstrates how variables become placeholders in an equation.
