1. Complete this table. Describe and discuss your methods.
Describe and discuss what patterns you see in the table.
Figure number 1 2 3 4 5 6 30
Number of pink triangles 1 3 5 7
Number of green triangles 3 5
Total number of triangles 4 8
2. Make a flow diagram to show how the number of pink
triangles can be calculated. Use the Figure numbers as the
input numbers and the number of pink triangles as the output
numbers. Complete all missing parts.

3. Repeat question 2, but this time make a flow diagram to
show how the number of green triangles can be calculated.
4. Repeat question 2 again but show how the total number
of triangles can be calculated.
