Worked examples

Real problems from the practice worksheets, solved one step at a time.

1. Example 1

   ??

   Fill in the missing terms

   1. Find the part that repeats: square, circle, circle. The pattern says it again and again.
   2. Split the row into groups of 3: (square, circle, circle) (square, circle, circle) (square, circle, ?) (?, …).
   3. Fill in the question marks so every group matches (square, circle, circle): (square, circle, ?) becomes (square, circle, circle); a new group starts: (square, …).
   4. So the missing shapes are circle, square.

   Answer: circle, square

2. Example 2

   ??

   Fill in the missing terms

   1. Find the part that repeats: star, circle, circle. The pattern says it again and again.
   2. Split the row into groups of 3: (star, circle, circle) (star, circle, circle) (?, ?, …).
   3. Fill in the question marks so every group matches (star, circle, circle): a new group starts: (star, circle, …).
   4. So the missing shapes are star, circle.

   Answer: star, circle

3. Example 3

   ??

   Fill in the missing terms

   1. Find the part that repeats: square, heart, heart. The pattern says it again and again.
   2. Split the row into groups of 3: (square, heart, heart) (square, heart, heart) (square, heart, ?) (?, …).
   3. Fill in the question marks so every group matches (square, heart, heart): (square, heart, ?) becomes (square, heart, heart); a new group starts: (square, …).
   4. So the missing shapes are heart, square.

   Answer: heart, square
