This worksheet helps students practice addition doubles facts (e.g., 1+1, 2+2, 3+3, etc.) using visual ten frames to build conceptual understanding. Each problem includes a pair of ten frames—one for each addend—allowing students to represent the doubles fact with counters or drawings before writing the equation and sum.

This quiz assesses students’ understanding of addition doubles facts up to 12 + 12. Each problem presents a basic doubles equation (e.g., 1 + 1, 2 + 2, 3 + 3, etc.) and requires students to write the correct sum. The quiz focuses on fluency, accuracy, and automaticity with doubles facts, which serve as foundational skills for future addition strategies. At the end of the quiz, there are two bonus challenge questions—20 + 20 and 100 + 100—to encourage students to apply their doubles knowledge t
