Variable Side 1 Side 2 A symbol, usually a letter that represents on or more numbers n x LT: I can identify and describe patterns

Input Side 1 Side 2 the input is the number you put in to get the output Example LT: I can identify and describe patterns If the output is 4 and to get the output you multiply by 2, then the input is 2.

Output Side 1 Side 2 The output is the result of the input when entered into an equation Example If the input is 4 and to get the output you multiply by 2, then the output is 8. LT: I can identify and describe patterns

With you’re a/b partner, identify where you see patterns in the real world. Be ready to discuss with class. music investments sleep habits nature LT: I can identify and describe patterns

From pictures or physical models we can sometimes find both numerical and geometrical patterns. LT: I can identify and describe patterns

Understanding a pattern can help us: extend the pattern create new patterns LT: I can identify and describe patterns

MODELS Mathematicians … look for patterns find patterns in physical or pictorial models look for ways to create different models for patterns use mathematical models to solve problems LT: I can identify and describe patterns

Problem 1 Identifying a pattern Look at the figures from left to right. What is the pattern? Draw the next figure in the pattern. a. b. Answer: The next figure would have 7 sides Answer: Length of arm increases by one block the center remains the same LT: I can identify and describe patterns
