2nd Grade · The Broken Ruler
Seven is when a child stops accepting the tool they were handed and starts asking what the tool is actually doing.
Full screen — no distractions
Where this goes
The ladder
The same idea, three times, roughly a year apart. This is what depth looks like from the outside.
This year
Lengths as differences, on a ruler with no zero.
Next year
Negative numbers — the same idea with the zero moved somewhere else.
The year after
Measuring what a ruler cannot reach: a tree's height from its shadow.
What lives on the desk this year
- A ruler, and permission to snap a card one
- Squared paper
- String, for the things a ruler cannot follow
- A kitchen scale
- A notebook with the date at the top of every page
The rest of 2nd Grade
One hard thing a day is the sharp end. It sits on top of an ordinary year.
