By grade
What students need to know
Sides are the straight edges and vertices are the corners. Mark where you start so you count each one just once.
This skill runs from 1st grade through 2nd grade. Pick a grade above for level-matched sentences, teaching notes, and worksheets.
Sides & vertices across the grades
1st grade
Sides and vertices worksheets for first grade show one shape at a time (triangle, square, rectangle, or hexagon) with a single question, how many sides or how many vertices, and a writing line for the count.
2nd grade
Second grade sheets widen the lineup: pentagons, octagons, rhombuses, trapezoids, and general quadrilaterals join the first grade shapes, so answers run from three up to eight. The question stays the same: count the sides or vertices and write the number.
