Hope and Ana - Maths Algebra


1.




a. How many sticks were needed to build the 5 fish patterns?  
32
b. How many sticks would you need to build 20 fish patterns? (See if you can work out how many without making the pattern)  
122
c. Explain how you worked this out.  
1 fish = 6 Sticks so 6 x 20 = 120 + the 2 sticks from the first fish tail.
d. In a spreadsheet create a table that shows how many sticks are needed for up to 20 fish.
