Growing Mosaics: Patterns That Grow

Marlo the chameleon mosaic artist builds patterns that grow, one step at a time. Students continue patterns of circles, bottle caps and pattern-block giraffes from their rules, fill in tables of totals, and spot what a rule doesn't say: totals that alternate odd and even, or that are always multiples of 5 or 10. They use those features to decide whether a number can ever appear in a pattern, find which step reaches a total, and finish by telling what stays the same and what changes in a tower of blocks. Every direction is narrated, and each wrong answer gets a hint. Built for Grade 4 patterns (4.OA.C.5).

• 15 interactive scenes with narrated directions
• Pattern tables for circles, bottle caps and block giraffes
• Odd, even and multiples reasoning questions
• Pattern-block tower comparison
• Hints on every wrong answer

• Continue a growing pattern of shapes from its rule and record the totals in a table.
• Notice features a rule doesn't state, such as totals that are always even or always multiples of 5.
• Use those features to decide whether a number can be in a pattern, without drawing every step.
• Tell what stays the same and what changes as a pattern grows.
