Math: Function Tables Input and Output
Find the rule and complete the table
Math - Grade 2-3
- 1
Rule: Add 2. If the input is 5, what is the output?
Start with 5 and count forward 2.
The output is 7 because 5 + 2 = 7. - 2
Rule: Add 3. Complete the table: Input 1 gives Output 4. Input 2 gives Output 5. Input 3 gives Output blank. What is the missing output?
The missing output is 6 because 3 + 3 = 6. - 3
Rule: Subtract 1. If the input is 9, what is the output?
Start with 9 and count back 1.
The output is 8 because 9 - 1 = 8. - 4
Rule: Add 5. Complete the table: Input 0 gives Output 5. Input 1 gives Output 6. Input 4 gives Output blank. What is the missing output?
Add 5 to the input number.
The missing output is 9 because 4 + 5 = 9. - 5
Rule: Double the input. If the input is 6, what is the output?
Double means add the number to itself.
The output is 12 because double 6 means 6 + 6 = 12. - 6
Look at the pairs: 2 goes to 4, 3 goes to 6, and 5 goes to 10. What is the rule?
The rule is double the input because each output is two times the input. - 7
Rule: Add 10. Complete the table: Input 7 gives Output blank. Input 8 gives Output 18. Input 9 gives Output blank. What are the missing outputs?
Add 10 to each input.
The missing outputs are 17 and 19 because 7 + 10 = 17 and 9 + 10 = 19. - 8
Rule: Subtract 2. If the output is 6, what input was used?
To find the input, do the opposite operation and add 2 to the output.
The input was 8 because 8 - 2 = 6. - 9
Rule: Add 4. Complete the table: Input blank gives Output 10. What is the missing input?
The missing input is 6 because 6 + 4 = 10. - 10
Look at the table: Input 1 gives Output 3. Input 2 gives Output 4. Input 5 gives Output 7. What is the rule?
Compare each input to its output and see how much was added.
The rule is add 2 because each output is 2 more than the input. - 11
Rule: Subtract 3. Complete the table: Input 8 gives Output 5. Input 10 gives Output blank. Input 12 gives Output blank. What are the missing outputs?
Subtract 3 from each input.
The missing outputs are 7 and 9 because 10 - 3 = 7 and 12 - 3 = 9. - 12
Rule: Add 1. The inputs are 4, 5, and 6. What are the outputs?
The outputs are 5, 6, and 7 because each input has 1 added to it. - 13
A function machine uses the rule add 6. Nina puts in 3. What number comes out?
The input is the number that goes into the machine.
The number 9 comes out because 3 + 6 = 9. - 14
A function machine uses the rule double the input. Sam puts in 4, then 5, then 7. What numbers come out?
The numbers 8, 10, and 14 come out because double 4 is 8, double 5 is 10, and double 7 is 14. - 15
Look at the pairs: 6 goes to 4, 8 goes to 6, and 9 goes to 7. What is the rule?
Check how the output changes from the input in each pair.
The rule is subtract 2 because each output is 2 less than the input.
