Building+Structures

=Building Structures with Toothpicks, Playdough and Straws =

- Straws - Toothpicks - Playdough - Cardboard bases - Scissors - Tape
 * Materials:**

- Build two bases, one with toothpicks, one with straws - Put bases in center of meeting circle - Ask kids to share ideas of what the structures are
 * Opener:**


 * Activity Description**:

//**Results:**// - Popular activity - Able to do activity outside - 6 boys, 7 girls - Used all materials, including using rocks as base for structure - Needed more playdough or could have suggested using tape to put structures together

**//Topic:Properties of Shapes//**
K.G.1 Name, describe, sort and draw simple two-dimensional shapes (PreK,K) K.G. 2 Describe attributes of two-dimensional shapes, e.g. number of sides, number of corners (PreK,K) K.G.3 Name and compare three-dimensional shapes (PreK, K) K.G.4 Identify positions of objects in space, and use appropriate language (e.g. bedside, inside, next to, close to, above, below apart) to describe and compare their relative positions (PreK, K) 2.G.1 Describe attributes and parts of two- and three dimensional shapes (length of sides and number of corners, edges, faces and sides) (1,2) 2.G.6 Predict the results of putting shapes together and taking them apart (1,2) 2.G.7 Relate geometric ideas to numbers, eg, seeing rows in an array as a model of repeated addition 3.G.2 Identify and describe simple three-dimensional shapes, eg: cubes, spheres, and pyramids (3) 3.G.3 Identify angles as right angles, less than a right angle and greater than a right angle. (3) 3.G.4 Identify parallel lines, perpendicular lines and other intersecting lines (3) 4.G.1 Compare and analyze attributes and other features (eg: number of sides, faces, corners, right angles, diagonals and symmetry) of two and three dimensional geometric shapes (4) 5.G.2 Identify, describe and compare special types of three dimensional shapes (cubes, prisms, spheres, pyramids) based on their properties, such as edges and faces (5) 5.G.3 Indentify relationships among points and lines, eg: intersecting, parallel, perpendicular.
