Teaching Table · Reviewed guide
Set out your lesson
“We compare height with taller and shorter. We compare length with longer and shorter. Line the objects up at the same baseline before deciding.”
Bring to the table
- Two books or boxes with clearly different heights
- A ribbon, string, or strip of paper longer than both objects
Full guide and materials
- Two books or boxes with clearly different heights
- A ribbon, string, or strip of paper longer than both objects
- Step 1. Stand two books or boxes on the same flat surface side by side.
- Step 2. Ask which is taller and which is shorter. Have your child use both words.
- Step 3. Lay the ribbon beside a book and beside a box or second object to compare length.
- Step 4. Ask which is longer and which is shorter, keeping the starting ends even.
- Quick check. Present two objects that differ in height or length. Success means your child correctly names the taller/shorter pair or the longer/shorter pair.
Worked example. If one book stands clearly above the other from the same table surface, that book is taller and the other is shorter.
Optional challenge. Add a third object and order all three from shortest to tallest, saying the comparison words as you go.
What to notice. Save a parent note naming the two objects and the comparison words your child used.

Check understanding
- Stand two children back-to-back and say who is taller/shorter
- Directly compare the heights of two towers and describe one as taller
- Use 'longer' and 'shorter' to compare two ribbons placed side by side
“If your child stands next to the kitchen table and the front door, can they tell you which is taller — and whether they themselves are shorter or taller than each one?”
