Figure out the rule a function machine is using by looking at the input and output numbers. Write an equation that matches a number pattern, using a variable for the input. Decide which operation (add, subtract, multiply, or divide) connects the input to the output.
4oa5
Figure out the rule that connects the input and output numbers in a table. Check that the same rule works for every row in the table.
4oa5
Figure out what operation is happening in a number pattern (add, subtract, multiply, or divide). Explain the pattern rule in simple words, like “add 3 each time.” Check that a rule works for every step in the pattern, not just one pair of numbers.
4oa5
Find the area of a grid by counting square units. Notice how a shape or grid is growing from one step to the next. Use the pattern to predict the area of the next shape in the sequence.
4oa5
Figure out the rule that changes an input number into an output number. Choose which operation and number make the rule work for all the examples in a table.
4oa5
Find the missing number in a sequence by spotting what changes each step. Figure out whether a pattern is using addition, subtraction, multiplication, or division. Use the pattern rule to keep the sequence going and check that it stays consistent.
4oa5
Figure out what operation (add, subtract, multiply, or divide) changes one number into the next in a pattern. Compare answer choices and pick the rule that matches all the numbers in the pattern.
4oa5
Figure out whether a number pattern is going up by adding or going down by subtracting. Use the change between numbers to identify the rule in a sequence. Choose which rule matches a given pattern when there are several options.
4oa5
Match a single operation rule to the input/output table it produces. Test a rule against every row of a table, not just the first. Recognize that one row alone can fit more than one rule.
4oa5
Describe a growing pattern of squares with a single operation rule. Count the squares in each figure before choosing a rule. Test a rule against every figure, not just the first two.
