STARTER – CRACK THE CODE OUTCOME 9 I 3114 CAN CONVERT USING BINARY

OUTCOMES All students will be able to convert using 8 bit numbers Most students will be able to convert between binary, denary and binary to hexadecimal. Some students will be able to convert confidently between binary, denary and hexadecimal Objective: I can convert using binary, denary and hexadecimal numbers

HOW DO COMPUTERS TALK? Objective: I can convert using binary, denary and hexadecimal numbers

EXAMPLE = On 0 = Off Take the “On” numbers and add them together 8+1 = 9 So; 1001 in Binary is equal to the denary (integer) 9 Objective: I can convert using binary, denary and hexadecimal numbers

TASK ONE - A BinaryDenary ) So how ….. can I represent the number 256 in binary? Objective: I can convert using binary, denary and hexadecimal numbers

TASK ONE - A BinaryDenary ) So how ….. can I represent the number 16 in binary? Objective: I can convert using binary, denary and hexadecimal numbers

CAN WE MAKE NUMBERS INTO BINARY? So we know that is equal to 5 but how to we make numbers into binary code. Simple! Objective: I can convert using binary, denary and hexadecimal numbers

DENARY TO BINARY 99 = Why? = Objective: I can convert using binary, denary and hexadecimal numbers

TASK ONE – B – CONVERT THE DENARY BinaryDecimal ) So what is in denary form? Objective: I can convert using binary, denary and hexadecimal numbers

TASK ONE – B – CONVERT THE DENARY BinaryDecimal ) So what is in denary form? Objective: I can convert using binary, denary and hexadecimal numbers

PROGRESS CHECK Can we all confidently convert using 8 bit binary numbers? Objective: I can convert using binary, denary and hexadecimal numbers

THE SOLUTION TO BIGGER NUMBERS …. Sometimes binary numbers get really long – so we use Hexadecimal to shorten them – making them easier to store and remember. In this example, the relatively small number of 42,780 in binary is Objective: I can convert using binary, denary and hexadecimal numbers

CONVERSION TO HEXADECIMAL A 7 1 C 1)Split the binary into groups of 4 2)Using the table system convert to denary numbers 3)Use the Hex table to convert ABCDEF
