# Geometry Learning Objects

## Level 1

 Direct a Robot requires users to guide a robot to collect objects by providing directions and distances (more info). Direct a robot: collector Direct a robot: which way? Direct a robot: how far? Shape Overlays asks users to overlay 2D shapes to create other shapes (more info). Shape overlays: find and cut Shape overlays: picture studio Shape overlays: find, cut and turn Shape overlays: picture puzzle Tesselate Decorate asks users to use a range of shapes, or combinations of shapes, to make tessellations to decorate the living room in a house. (more info). Tessellate decorate: rectangles NLVM: Space manipulatives Attribute blocks Tessellations Pattern blocks Geoboard Polyominoes

## Level 2

 Face Painter requires users to identify the faces of 3D objects that are a certain 2D shape (more info). Face painter: finding faces 1 Face painter: finding faces 2 Face painter: locating faces Face painter: predicting faces Finding Symmetry helps users determine whether shapes have one, two or three lines of symmetry (more info). Finding symmetry: three lines: garden NLVM: Space manipulatives Attribute blocks Pentominoes Tessellations Pattern blocks Geoboard Polyominoes
