Mosaic Borders: Patterns That Repeat

Help Marlo the chameleon mosaic artist read repeating borders of tiles and shapes. Grade 4 students flash-count a strip of colored tiles, find the group that repeats and how many times it fits, then use multiples to name the 25th, 31st or 50th shape without drawing them all. Every direction is narrated, wrong answers get a spoken hint, and two cool-down questions close the lesson. About 12 minutes, one student per device.

• Spoken hints on every wrong answer, and results a teacher can read per question
• 14 scenes: an opening, 12 narrated activities (a tile flash, repeating-pattern questions and a two-question cool-down) and an ending

• Find the group of shapes that repeats in a pattern and count how many times it repeats.
• Tell where a shape will be, using the multiples of the group's size.
• Find the shape in a far-off position, like the 31st or the 50th, without drawing them all.
