Lesson details
Key learning points
- The process of counting in binary follows the same principle as decimal.
- Binary addition can be achieved with the following facts: 0+0 = 0, 0+1 = 1, 1+1 = 10 and 1+1+1 = 11.
Keywords
Addition - a mathematical operation where two or more numbers are combined to find their total
Carry - the extra value that moves to the next column when the sum of digits in a place value exceeds the base
Common misconception
Pupils will often default to decimal addition, in the fact that 1+1 = 2, whereas in binary 1+1 = 10.
Remind students that binary only has two digits; 0 and 1. Use the comparisons between binary and decimal addition in the slide deck to illustrate the differences.
