Investigation 3

Monday:

Hand out 2D shapes; make a list of the things you can list as attributes: number of sides, number of points or angles, right angles, quadrilateral, 2D

Kids go make their own lists of attributes of 2D shapes

Focus on vocab: polygon, quadrilateral, right angles (check each shape for right angles), vertex (vertices), congruent, edges, attribute, characteristic, feature

Introduce symmetry. See p. 121. Look at some shapes and have kids say if they are symmetrical or not; fold them to see if they are. Think of things that are symmetrical in the world. Introduce using mirrors to test for symmetry if there’s time.

Tuesday:

Hand out 3D shapes; make a list of the things you can list as attributes: number of faces, number of sides, number of points or corners, right angles, 3D, sides are the same length or different lengths, shape of faces

Kids go make their own lists of attributes of 3D shapes

Focus on vocab: polygon, quadrilateral, right angles (check each shape for right angles), congruent, vertices (vertex), attribute, characteristic, feature

Talk about how 3D shapes look on paper and how you have to imagine them as real shapes you can hold in order to count faces or points.

Teach Mirror Designs activity and have kids practice making symmetrical designs with pattern blocks.

Wednesday:

Teach Symmetrical Geoblock buildings (p.123). Kids build their own.

Centers: Geoblock buildings, Mirror Designs, Basic facts flashcards and practice.

Thursday:

Teach Copy Tiles (p. 128)

Centers: Copy Tiles, Mirror Designs, basic facts, geoblock buildings
