What children learn in Level 45
- An input-output table uses a rule. Put a number in, use the rule, and out comes a new number. Rule: multiply by 6.
- 2 times 6 is 12, and 5 times 6 is 30. So 9 gives 9 times 6: 54.
- To find a missing input, work backward. Which input gives 42? Undo multiplying by 6: 42 divided by 6 is 7.
Georgia's K-12 Mathematics Standards:
- 4.PAR.3.2 — Use input-output rules, tables, and charts to represent and describe patterns, find relationships, and solve problems.
