Hand Span! Giant Marbles Meet Up

In pairs, one child rolls a giant marble and the other tries to stop theirs within a "cuarta" (one open-hand span) of it, as in the traditional Mexican marbles game. It works on controlling how hard you roll and on measuring distance with the body.

How to play

1. The teacher shows what a cuarta is: an open hand, from thumb to pinky. Each child measures their span on the ground and compares it with a partner's (2 min).
2. In pairs, each with a different-colored ball. The first child gently rolls their marble across the yard; the second, from the same spot, tries to stop theirs right next to it (3 min).
3. Measure with your hand: if one span or less fits between the marbles, the pair shouts "¡Cuarta!" and high-fives; if not, count how many spans there are (3 min).
4. Keep playing from where the marbles stopped, switching who rolls first, like a marble walk all over the yard (3 min).
5. Finish: every pair tries to leave their marbles within a span of a center cone, making one big marble flower together (1 min).

Rules

• We roll softly so the marble doesn't get away.
• We measure with an open hand without pushing the marbles.
• When it's a "cuarta," the whole pair wins.

Variations

Adaptations

• Limited mobility: roll from the wheelchair with a ramp and measure with a stick one span long.
• Visual impairment: the partner's marble has a bell attached, and measuring is done by guiding the hand along the ground.
• Autism: set a fixed turn order with "my turn" and "your turn" cards.

Learning goals

• Control force when rolling a ball.
• Measure distance with the hand.
• Play in pairs, taking turns.

Equipment for a class of 25

• Medium playground balls: 26

Teacher tip

In traditional marbles, if your marble stops within a span of your opponent's, you win it; here the "cuarta" is a shared win for the pair. With 3-year-olds, keep the partner's marble still, since they're still learning to control how hard they roll.
