Lesson 5: Math is BoundlessMPP.7

I can…

I can create and describe geometric designs using repetition, patterns, and rhythm, and use a pattern unit to predict what comes next.

Key words

• repetition — The same shape used again and again.
• pattern — Something that repeats or changes by a rule.
• pattern unit — The smallest part that repeats.
• rhythm — Changing the size, spot, or order of the same shapes.
• predictability — Knowing what comes next because of a rule.

Steps

1. A border repeats: pink circle, purple square, blue triangle, pink circle, purple square, blue triangle, ...
2. The pattern unit is 3 shapes long: circle, square, triangle.
3. To predict shape number 12, I divide: 12 ÷ 3 = 4 with no remainder, so shape 12 ends a complete unit — it is the blue triangle.
4. The next three shapes after any complete unit will be a pink circle, a purple square, and a blue triangle.

Try it

Draw a pattern with a pattern unit of your own — at least 3 shapes long.
