Prerequisites
How to Solve Group by Size Problems
Step 1: Observe the relative sizes of all figures
Step 2: Look for a clear size distinction - one group is noticeably larger
Step 3: The other group is noticeably smaller
Step 4: Count figures in each size category
Step 5: The classification basis is size (large vs small)
Step 6: Answer the grouping basis
Example Problem
Example: Three large circles and three small circles are shown. How are they grouped? Solution: Step 1: Group 1: Large circles (greater area/diameter) Step 2: Group 2: Small circles (smaller area/diameter) Step 3: Classification basis = Size (large vs small) Answer: Grouped by size
Pro Tips & Tricks
- Size comparison is relative - look for two distinct size clusters
- Large shapes typically occupy 2-3 times the area of small shapes
- Size classification works regardless of shape type or color
- The actual dimensions don't matter - only the relative distinction
- Look for consistent size within each group
- If sizes vary gradually, size may not be the classification basis
