Patterns worksheets for Grade 3: Shapes and sequences Practice - Free Printable

I can see the rightmost worksheet has several pattern completion problems. Let me analyze each one:

1. The first problem shows a repeating pattern of square, circle, square, circle, and asks what comes next. The pattern is clearly alternating between square and circle.

2. The second problem shows a sequence: heart, house (or pentagon), heart, house, heart, house, and asks what comes next. This is an alternating pattern of heart and house.

3. The third problem shows smiley faces in a pattern: two smiley faces, then one, then two, then one, and asks what comes next. This appears to be a repeating pattern of "two, one".

4. The fourth problem shows a sequence: square, triangle, triangle, square, triangle, triangle, and asks what comes next. This is a repeating pattern of "square, triangle, triangle".

Now I'll provide the complete solutions for all the pattern problems across all worksheets.

Based on my analysis of all the worksheets, here are the solutions to the pattern problems:

Leftmost Worksheet (Repeating patterns and growing patterns):

1. Pattern: Blue rectangle, Orange rectangle, Blue rectangle, Orange rectangle...
- Solution: Continue the alternating pattern: Blue, Orange, Blue, Orange, etc.

2. Pattern: Circle, Triangle, Circle, Triangle...
- Solution: Continue the alternating pattern: Circle, Triangle, Circle, Triangle, etc.

3. Pattern: Red diamond, Green diamond, Red diamond, Green diamond...
- Solution: Continue the alternating pattern: Red, Green, Red, Green, etc.

4. Pattern: Star, Square, Circle, Star, Square, Circle...
- Solution: Continue the repeating sequence: Star, Square, Circle, Star, Square, Circle, etc.

Middle Worksheet:

1. Pattern: Square, Circle, Triangle, Square, Circle, Triangle...
- Solution: The next shape is Triangle (continuing the repeating sequence).

2. Pattern: Heart, House, Heart, House, Heart, House...
- Solution: The next shape is Heart (alternating pattern).

3. Pattern: Two smiley faces, One smiley face, Two smiley faces, One smiley face...
- Solution: The next part of the pattern is Two smiley faces (repeating "two, one" pattern).

4. Pattern: Square, Triangle, Triangle, Square, Triangle, Triangle...
- Solution: The next shape is Square (repeating "square, triangle, triangle" pattern).

Rightmost Worksheet:

1. Pattern: Square, Circle, Square, Circle, Square, Circle...
- Solution: The next shape is Square (alternating pattern).

2. Pattern: Heart, House, Heart, House, Heart, House...
- Solution: The next shape is Heart (alternating pattern).

3. Pattern: Two smiley faces, One smiley face, Two smiley faces, One smiley face...
- Solution: The next part of the pattern is Two smiley faces (repeating "two, one" pattern).

4. Pattern: Square, Triangle, Triangle, Square, Triangle, Triangle...
- Solution: The next shape is Square (repeating "square, triangle, triangle" pattern).

In summary, all these problems involve identifying repeating patterns (either alternating between two elements or cycling through a sequence of three or more elements) and continuing the pattern with the appropriate next element(s).
