Binary Place Value Foundations
What students learn
Students learn that binary uses only two symbols, zero and one, to represent numbers and information. Start with to connect the system to computers.
Why it matters
Binary is still a place-value system, so each digit has meaning based on where it sits. makes that structure visible.
Learn the idea
Instead of multiplying by ten each place, binary doubles each place. shows the key pattern.
Try it
Ask the student to write the binary place values 1, 2, 4, 8, 16, and 32. Then have them point to the values that would build the number 13.
Parent guide
Keep the focus on place value. If the string of zeros and ones feels confusing, cover the digits and reveal one place at a time.
