In this interactive mathematics activity, students develop foundational addition skills by counting sets of fish and combining them to form equations. Students drag numbers to represent quantities and build addition sentences with sums up to 10 or 20. This activity supports TEKS K.3.C (explain strategies for solving addition problems) and aligns with Common Core K.OA.A.2 (solve addition word problems).
Skills: counting, number recognition, addition fluency, equation building. Differentiation: Adjustable levels for sums to 10 or 20. Available in Spanish.
