Decode four binary places
Use powers of two to translate a small binary number.
Open lesson 1Represent and Check Small Binary Data
Decode and encode unsigned values, distinguish pixel interpretation and test a toy parity check.
Before you begin
- Add place values; count symbols; read rows and columns.
Choose by skill rather than age alone. Read with an adult when useful, revisit a lesson, or explore another grade.
Follow the lesson sequence
Encode a Value and Check the Range
Construct unsigned four-bit numbers and reject an out-of-range value.
Open lesson 2Decode a Tiny Binary Picture
Use bit positions as pixels instead of number places.
Open lesson 3Check a Simple Parity Rule
Add an even-parity bit and state which changes the check can miss.
Open lesson 4Review and transfer
After the lessons, try 4 new review cases and a practical task. Each answer has an explanation and a link back to the related lesson.
