Easy tangrams show the internal piece boundaries inside the silhouette, so you can see exactly where each of the seven tans belongs — the puzzle becomes matching shapes to slots rather than solving blind. Silhouettes at this tier are compact and blocky, with most pieces sitting square to the frame.
This is the tier to build the habits the harder ones assume: park the two large triangles first, keep the square and parallelogram for the awkward gaps, and remember the parallelogram is the only piece that ever needs flipping.
