Treasures worth counting

Place large blocks, dot cards and three trays on a table. Each block becomes a treasure that must reach a small island drawn on paper. Begin with collections of one to three, using an empty tray to separate counted objects from those still waiting. Keep the answer out of a race: allow looking and touching before asking how many there are. A three-dot card can become an order for supplies needed by three imaginary explorers, giving the counting a purpose children can see and act on.

Move one block for each number word and place counted blocks in the empty tray. At the end, repeat the last number to name the total: one, two, three; we have three treasures. Spread the same blocks into a longer line and ask whether any new ones arrived. Children can count again or match them to the dots on a card. If one block receives two numbers, demonstrate moving it only once. Changing the arrangement of the objects may clarify the difficulty more effectively than repeating the instruction.

Use uno / one, dos / two and más / more while handing over actual quantities. Children aged three to four can put one block on each dot. At five or six, they can connect a collection with a numeral card and a dot card. For seven- to eight-year-olds, explore splitting six treasures between two islands: four and two, three and three, or another combination. Drawing both parts supports talk about the total without requiring numeral writing from a child who still needs objects to represent a quantity.

Each pair makes a map of its collection and chooses a record of the total: drawings, dots, a numeral or dictated words. Exchange maps so another team can build the same quantity. When differences appear, compare the record with the blocks before deciding that someone made a mistake. Save one collection for tomorrow and announce that a new treasure will arrive. Before adding it, invite predictions about what will change on the map and which part of the record will need an adjustment to match.

Make this idea your own: adapt the materials, pace and support to your group’s ages, interests and needs.
