Minds on: • This input/output machine multiples each input number by 7. • Output numbers are multiples of 7. Suppose you input 9, 20, 3, 5. What will the output be? Input Output 9 63 9 20 x 7 140 20 35 140 21 63 3 3 21 5 5 35
Explore • Choose a number and an operation to go in the first part of the machine. Choose a different number and a different operation to go in the second part of the machine. • Use the numbers 1 to 5 as input. Find the output for each input number. Record the input and output in a table. • Write the pattern rule for the output numbers. Describe how each output number is related to its input number. • Share your work with another classmate. Find the next 3 output numbers for your classmates' Input/Output machine.
Example • This Input/Output machine doubles each input, then adds 6. When the input is 1, the output is 8. When the input is 5, the output is 16. x 2 + 6 Output 8 Input 10 12 14 16
This time rewind…. • This table shows the input and output for this machine. Identify the numbers and operations in the machine. ? ? Output Input
