With Angle Type: Acute / Obtuse / Right Color by Number, the more problems students get right, the more of the picture appears. Students sort each answer into the right group, color by the key, and a hidden picture appears. Students classify angles as acute, obtuse, or right. Built for Grade 4 and aligned to 4.G.A.1. Print it for morning work and centers or assign the self-checking interactive version for home — each download includes the PDF and the digital answer-key version.
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
