Biggest to Smallest

What the activity builds

Compare, order, and hold an entire series in mind, a skill that will resurface later in math.

The materials

  • Five objects of the same kind, in evenly different sizes: boxes, cups, blocks, books
  • A mat

How to do it, step by step

  1. Mix the objects up on the mat.
  2. Find the biggest one out loud, and set it on the left.
  3. Find the biggest of what's left, and set it to the right of the first.
  4. Let your child finish the series, then step back to look at the staircase you've built together.

The parent's role

The vocabulary comes after the action: "bigger than," "the smallest of all." Name it only once the series is finished. Show once, then step back.

Safety

Avoid glass objects. If stacking, keep the tower at seated height.

You remain the sole judge of what is right for your child. These activities are offered for educational and recreational purposes: they do not replace medical advice or the guidance of an early childhood professional.

Ways to adapt the activity

  • Easier: three very contrasting objects.
  • Harder: seven objects, or sorting by weight, by holding each one.
  • Next step: arranging the bookshelf by height.
