Count Cluster

Dial through nine object goals (10–1000) to practice grouping the same shapes in scattered clusters or tight grids.

Observe → group → count

Count the objects, then choose the total.

Tap an answer to begin.

Use the slider to choose how many objects can appear in a round.

Object goal

Goal · 20 objects

Cluster sizes: 2–4 shapes

Counts vary up to 20 with fresh scatter layouts.

Focus: One-to-one correspondence & subitizing.

Hint: Say the groups aloud ("three apples up top, two stars on the right") before choosing a number.

Use the Object goal slider to choose how many shapes you want to count (10 up to 1000).
Press Deal new arrangement or wait for the auto advance to load a fresh field.
Check the cluster badge above the board to see how many items hide in each group.
Use your favorite strategy—subitize, skip-count, or add hundreds—then tap the total that matches what you see.
Watch the rounds, streak, and accuracy meters grow. Slide to a new goal anytime for a different challenge.

Counting huge sets feels easier when you lean on structure.

Small goals scatter dots loosely so you can subitize and skip-count.
Bigger goals arrange dots into tidy 4×5, 5×10, or 10×10 grids that highlight tens and hundreds.
Saying “I saw five groups of twenty” links the picture to multiplication and place value.

Explain how you found the total after every round to make your thinking extra strong.
