Question 13
1. Look at the first sequence and answer:
– How many unit squares are in the first figure?
– How many are in the second figure?
– How many rows and columns does the second figure have?
– How is the number of squares related to the rows and columns?
– Use this relationship to find the number in the third figure, then predict the fourth.
2. The second sequence contains purple and yellow squares.
– How many rows and columns are in each of the first three figures? What is their pattern? Find the rows, columns and total squares in the fourth figure.
– How do the yellow-square counts in the first three figures compare with the counts in part 1?
– How many yellow squares are in the fourth figure?
– How many purple squares are in the fourth figure?
– How many unit squares are in the first figure?
– How many are in the second figure?
– How many rows and columns does the second figure have?
– How is the number of squares related to the rows and columns?
– Use this relationship to find the number in the third figure, then predict the fourth.
