What this lesson shows
Fixes a mistake
A kid's table for 10 + 2n puts 14 in the input column, and gets 36 for input 3 by adding first. Inputs left; multiply first.
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
- Inputs left, outputs right
- Multiply first, then add
- Check each row
Helping at home
Inputs always go on the left and outputs on the right. In a rule like 10 + 2n, 2n means 2 times the input: multiply first, then add. Check each row against the rule.
If your kid gets stuck
Inputs left. Multiply first, then add.

- 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.
