Computer science
Grade Levels: Grade 7
Educational System: STEM
Create a Computer Science course for Grade 7 starting from absolute zero knowledge. The school year has 4 quarters (24 lessons, each lesson = 1 hour). The curriculum should teach C++ from the very basics as they are new to programming and i want to make them know just basics and some structure programming Each lesson should be interactive, with coding practice and quizzes. At the end of every quarter, add a small project that applies the learned concepts.

1. Convert between binary and decimal number systems and vice versa
Learning Targets:
1. Convert decimal integers in the range 0–255 to binary manually using repeated division and confirm correctness.
2. convert binary nunbers into decimal
Modules
1. Binary Concepts and Decimal-to-Binary Conversion
1. 1. Represent Numbers in Binary
Learning Outcomes:
1. Explain base-2 using place values and compare to base-10 with small examples.
2. Evaluate sample binary numbers and state their decimal value to check understanding.
1. 2. Convert Decimal (0–255) to Binary by Repeated Division
Learning Outcomes:
1. Convert a given decimal integer (0–255) to binary manually using repeated division by 2 and record remainders.
2. Validate results by reconverting the binary back to decimal using place values.
2. Binary-to-Decimal Conversion and Verification
2. 1. Convert Binary to Decimal Accurately
Learning Outcomes:
1. Compute decimal values from binary strings by summing weighted bits (1s times powers of two).
2. Trace the conversion step by step for 8-bit inputs and verify with a calculator or code.
3. Detect invalid binary input (characters not 0/1) and prompt for correction.
4. Demonstrate how leading zeros do not change the decimal value and verify with examples.
5. Cross-check conversions by round-tripping: decimal -> binary -> decimal for sample numbers.
6. Explain common mistakes (bit order, missing weights) and show how to avoid them.
