Tips for Parents
▸ What is on the sheet Each circle is filled a quarter at a time. Find how the filled portion cycles across rows and columns, and circle the piece that completes the grid. Compare the amount shaded, not the angle of the wedge. The four states cycle through 0, 1/4, 1/2 and 3/4. ▸ Try one example 1. C Row 1: 0 → 1/4 → 1/2 Row 2: 1/2 → 3/4 → 0 Row 3: 0 → 1/4 → 1/2 Column 3: 1/2 → 0 → 1/2 ▸ Check a difficulty Compare the amount shaded, not the angle of the wedge. The four states cycle through 0, 1/4, 1/2 and 3/4. Apply the same row and column rule to the missing cell. Compare each option with the required features. ▸ Choose the next step 2. A Row 1: 1/4 → 0 → 3/4 Row 2: 1/2 → 1/4 → 0 Row 3: 3/4 → 1/2 → 1/4 Column 3: 3/4 → 0 → 1/4
