Substitution Composer and Shape Composite Repeater (3D)

Substitutes a composite for a congruent whole. Builds complex bridges with multiple arches, with ramps and stairs at the ends. Structures are 3D, often including roofs and multiple internal spaces.

Other Examples:

  • A child creates a line of arches with ramps built close by to make a “parking garage” for toy cars. 

Help your student become a(n) Substitution Composer and Shape Composite Repeater (3D)

Activities for this and higher levels often involve creative construction with blocks and other construction manipulatives, with the teacher noticing, describing, and encouraging types of 3D composition that are at the next level for children (challenging, but achievable). Asking questions (Can you build another rectangular prism the same size and shape with other blocks? How will we build a series of arches along this whole wall?) or even putting up pictures of actual buildings or block buildings that illustrate that type of construct might motivate children to try that new way of composing 3D shapes. Copying each others' construction can be another helpful approach.
