Children complete pattern sequences by cutting and pasting images of flowers and butterflies.

I'll solve this "Garden Patterns" worksheet by identifying the pattern in each row and determining what should come next to complete it.

Let me analyze each row one by one:

Row 1:
- Pattern: Flower, Flower, Flower, Flower, Flower, Flower
- This is a simple repeating pattern of just flowers.
- Since all six positions are already filled with flowers, no additional piece is needed for this row.

Row 2:
- Pattern: Butterfly, Flower, Flower, Butterfly, Flower, Flower
- I can see a repeating pattern of "Butterfly, Flower, Flower"
- The pattern repeats twice: (Butterfly, Flower, Flower) + (Butterfly, Flower, Flower)
- All six positions are filled, so no additional piece is needed for this row.

Row 3:
- Pattern: Flower, Butterfly, Flower, Flower, Butterfly, Flower
- Let me look at this more carefully. It appears to be: Flower, Butterfly, Flower, then Flower, Butterfly, Flower
- This looks like a repeating pattern of "Flower, Butterfly, Flower"
- The pattern repeats twice: (Flower, Butterfly, Flower) + (Flower, Butterfly, Flower)
- All six positions are filled, so no additional piece is needed for this row.

Row 4:
- Pattern: Butterfly, Flower, Butterfly, Flower, Butterfly, Flower
- This is a simple alternating pattern: Butterfly, Flower, Butterfly, Flower, Butterfly, Flower
- All six positions are filled, so no additional piece is needed for this row.

Wait, let me re-examine the worksheet. I notice that each row has 6 positions, but there's a blank space at the end of each row where a piece should be pasted. Looking at the bottom of the worksheet, there are cut-out pieces: two flowers and two butterflies.

Let me reconsider each row to identify what's missing:

Row 1: Flower, Flower, Flower, Flower, Flower, Flower
- If this is meant to be a pattern that needs completion, and we have cut-out pieces available, perhaps it's simply continuing the flower pattern.
- The last position should be a flower.

Row 2: Butterfly, Flower, Flower, Butterfly, Flower, Flower
- The pattern is "Butterfly, Flower, Flower" repeating.
- The sixth position is already a flower, which completes the second repetition.
- But if we need to paste something in the blank space after the sixth position, it would be the start of the next repetition: a butterfly.

Row 3: Flower, Butterfly, Flower, Flower, Butterfly, Flower
- The pattern appears to be "Flower, Butterfly, Flower" repeating.
- The sixth position is a flower, completing the second repetition.
- The next piece in the pattern would be a flower (starting the third repetition).

Row 4: Butterfly, Flower, Butterfly, Flower, Butterfly, Flower
- The pattern is alternating "Butterfly, Flower".
- The sixth position is a flower, completing the third pair.
- The next piece in the pattern would be a butterfly (starting the fourth pair).

Looking at the cut-out pieces at the bottom, I have:
- Two flowers
- Two butterflies

This suggests that for the four rows, I need to use these four pieces to complete the patterns.

For Row 1: Since it's all flowers, the next piece should be a flower.
For Row 2: Following the "Butterfly, Flower, Flower" pattern, after the sixth position (which is a flower), the next should be a butterfly.
For Row 3: Following the "Flower, Butterfly, Flower" pattern, after the sixth position (which is a flower), the next should be a flower.
For Row 4: Following the "Butterfly, Flower" pattern, after the sixth position (which is a flower), the next should be a butterfly.

This matches perfectly with the available cut-out pieces: two flowers and two butterflies.

Therefore, the solution is:
- Row 1: Paste a flower in the blank space.
- Row 2: Paste a butterfly in the blank space.
- Row 3: Paste a flower in the blank space.
- Row 4: Paste a butterfly in the blank space.
