Making stick patterns II

This task is about making shape patterns, and finding a rule for the pattern.
  1. Use your ice block sticks to make shape 1 of the pattern below.  
    Add the correct number of sticks to make Shape 2 and then Shape 3.

    shape 1                             shape 2                                               shape 3
     box made from 4 sticks                 2 boxes made from sticks                      3 boxes made from sticks
     

  2. Add the correct number of ice block sticks to make shape 4 of the pattern. Draw these shapes in the spaces below.
                           shape 4                                                               shape 5  
 
 
 
 
  1. Write the number of ice block sticks you would use for each shape on the table below. The first two have been done for you.
     

    Shape Number of sticks
    1 4
    2 7
    3  
    ... ...
    7  
    10  
    6  

     

  2. Describe a rule that helps you work out the number of ice block sticks needed for any shape number. For example, write a rule that would help work out how many sticks are needed to make Shape 40.
