Mirror Below the Line: Horizontal Symmetry

The mirror line on this Grade 2 page runs across the page instead of down it, and the four figures — a rocket, an arrow, an ice cream and a robot, all drawn lying on their side — are complete above the line and empty below. The child mirrors each one downward, square by square: a square three rows above the line is copied three rows below, so up and down swap places while left and right stay exactly where they were.

This page exists to break a rule children invent for themselves. After a few vertical-line sheets, most of them conclude that symmetry means the left side matches the right — and then a horizontal axis arrives and their rule produces nonsense. Reflecting downward is also perceptually harder: our eyes compare side by side far more comfortably than they compare top to bottom, so counting has to take over from looking. Expect this sheet to take longer than the others, and treat that as the point of it rather than a problem with it.

Print the PDF free, and rotate the page a quarter turn if a child gets truly stuck — the familiar left-right view often unlocks it. Easy symmetry drawing and hard symmetry drawing are the vertical-line pages behind this one, and the complete-the-mirror-picture sheet is where the whole family begins.
