Partners discuss the outcome of their test and make conjectures about what they could do to improve the strength of their building. If time allows, partners test their new conjectures. The other partner will select all the geoblocks from the set that fit that attribute. The first partner names another attribute of the geoblock so that second partner can identify which of the smaller set of blocks chosen in the first round also fit the new clue. This continues until only one block is left, the secret block.
Partners trade places and repeat the activity.
Students work in pairs. Partners work together to draw the path that was walked. Students discuss the characteristics of the path. Students develop directions for particular shapes, such as squares, triangles, hexagons. Challenge students to develop directions for a circle.
