Shape mysteries: Identify the next two shapes in each pattern on this Year 3 brain training worksheet.

I will solve this "Shape mysteries" puzzle by analyzing the pattern in each row to determine which two shapes come next.

Let me go through each row one by one, looking for the repeating pattern.

Row 1:
- Shapes: Blue Square, Red Triangle, Red Triangle, Green Circle, Green Circle, Blue Square, Red Triangle
- Pattern seems to be: [Blue Square, Red Triangle, Red Triangle, Green Circle, Green Circle] then repeats.
- After Red Triangle, the next two should be: Red Triangle, Green Circle

Row 2:
- Shapes: Yellow Arrow (right), Blue Arrow (up), Brown Arrow (left), Red Arrow (down), Yellow Arrow (right), Blue Arrow (up)
- Pattern is a cycle of 4 directions: right, up, left, down, then repeats.
- After Blue Arrow (up), the next two should be: Brown Arrow (left), Red Arrow (down)

Row 3:
- Shapes: Green Star, Purple Star, Blue Moon, Orange Moon, Yellow Diamond, Red Diamond, Green Star
- Pattern appears to be pairs: [Green Star, Purple Star], [Blue Moon, Orange Moon], [Yellow Diamond, Red Diamond], then repeats with Green Star.
- After Green Star, the next two should be: Purple Star, Blue Moon

Row 4:
- Shapes: Blue Circle, Blue Circle, Green Pentagon, Red Diamond, Blue Circle, Blue Circle, Green Pentagon, Red Diamond
- Pattern is: [Blue Circle, Blue Circle, Green Pentagon, Red Diamond] repeating.
- After Red Diamond, the next two should be: Blue Circle, Blue Circle

Row 5:
- Shapes: Red Triangle (up), Red Triangle (down), Green Pentagon, Green Pentagon, Yellow Arrow (up), Yellow Arrow (down)
- Pattern seems to be: [Red Triangle (up), Red Triangle (down)], [Green Pentagon, Green Pentagon], [Yellow Arrow (up), Yellow Arrow (down)]
- After Yellow Arrow (down), the pattern should repeat from the beginning: Red Triangle (up), Red Triangle (down)

Row 6:
- Shapes: Orange Heart, Purple Plus, Green Circle, Blue Square, Orange Heart, Purple Plus, Green Circle
- Pattern is: [Orange Heart, Purple Plus, Green Circle, Blue Square] repeating.
- After Green Circle, the next two should be: Blue Square, Orange Heart

Now I'll summarize the solution for each row:

1. Red Triangle, Green Circle
2. Brown Arrow (left), Red Arrow (down)
3. Purple Star, Blue Moon
4. Blue Circle, Blue Circle
5. Red Triangle (up), Red Triangle (down)
6. Blue Square, Orange Heart
