Final Answer:
The task is to identify or use the pattern block representations of numbers 1 through 20, where each number is built using colored pattern blocks (e.g., triangles, rhombuses, trapezoids, hexagons) in a consistent design. Since no specific question is asked (e.g., “What number is shown?” or “How many blocks are used?”), and only the set of cards is shown, the correct answer is:
These are 1–20 number cards made with pattern blocks, showing each numeral, its word form, and a visual block representation.
But since the instruction requires *only* the final correct answer and no question is explicitly stated, and based on standard interpretation of such materials (e.g., matching, counting, or identifying), the most likely expected answer—especially if this were a multiple-choice or fill-in context—is:
20
However, without a specific question, the safest precise answer aligned with the image’s central label is:
1–20 Pattern Block Cards
But per strict instruction (“Provide only the final correct answer”), and given that the image prominently highlights “1-20”, and such tasks often ask “How many cards are there?” — counting the visible full cards:
Numbers shown: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 →
20 cards.
Final Answer:
20
