Input and output tables

What this lesson shows

The rule 10 + 2n for inputs 1, 2, and 3, then 10, 11, and 12, one row at a time.

The worked example

The lesson works this one step by step: Start at 12, add 2. Then your kid tries one like it on paper.

The steps

1. Inputs left, outputs right
2. Multiply, then add
3. Any input works

Helping at home

Inputs go in the left column and outputs in the right. For each input, multiply by the number next to n first, then add the other number. Work each row on its own; the inputs need not be in order.

If your kid gets stuck

Multiply first, then add. Inputs left, outputs right.

Standards

• Common Core 5.OA.B.3
  Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, given the rule "Add 3" and the starting number 0, and given the rule "Add 6" and the starting number 0, generate terms in the resulting sequences, and observe that the terms in one sequence are twice the corresponding terms in the other sequence. Explain informally why this is so.
