The Quick Check needs JavaScript. You can still open the three practices it comes from.
Mental rotation
Look at two shapes. Is the second one turned, or is it a mirror image?
Answer: Same, rotated. These are the same shape. The right figure has been turned a quarter turn. Follow the blocks from one end: the same bends stay connected.
Missing pattern puzzles
Find the rule across the rows or columns. Choose the tile that completes the pattern.
- Read each row from left to right. Apply the same rule in all three rows.
- Combine the marks in the first two tiles. A shared position appears once.
Visual memory
Study the pattern for as long as you like. When it disappears, select the same spaces.
Look for a shape, a cluster, or a small story in the tiles.
