 Design Process

Level 1

Level 2

Level 3

Level 4

- make increasingly   more informed and accurate measurement estimations based on an understanding of formulas (7m35)

 

- apply volume formulas to problem-solving situations involving rectangular prisms (7m31)

 

- solve problems related to the calculation and comparison of the perimeter and the area of irregular two-dimensional shapes (7m30)

 

 

 

-estimations made are unreasonable       

 

 

 

 

 

- calculations are incorrect

 

 

 

 

- models reflect limited understanding of scale calculations 

    

- work is not checked for miscalculations    

 

 

 

- estimations are usually reasonable

 

 

 

 

 

- calculations contain some inaccuracies

 

 

 

- models reflect some understanding of scale calculations 

    

- work is rarely  checked for miscalculations

 

 

- estimations are reasonable

Construction Process

Level 1

Level 2

Level 3

Level 4

 

 

-  sketch front, top, and side views of three-dimensional figures with or without the use of a computer application (7m54)

 

- sketch three-dimensional objects from models and drawings (7m55)

 

- build three-dimensional figures and objects from nets (7m56)

 

 

 

- the model is assembled but there are obvious flaws in the group’s constructions

 

 

 

 

 

 

 

- some components are missing or poorly constructed

 

 

- the model contains some solid construction components

 

 

 

 

 

 

 

 

- there are some inaccuracies in the components and/or the assembly of them

 

 

- the model is constructed and assembled accurately

 

 

 

 

 

 

 

 

 

- creativity and care are evident in the overall appearance of the structure

 

 

- the model is constructed and assembled accurately

 

 

 

 

 

 

 

 

 

- significant care and creativity are evident in the overall appearance of the structure
