Use geometric patterns to teach your class how to write functions. The assessment task has scholars consider a pattern of dots to draw the next picture of the pattern. Pupils then analyze the pattern, which helps them develop a function for the total number of dots in each picture.
- Have struggling learners draw more of the pattern to see relationships
- Pupils should have prior experience writing functions to represent patterns
- Note that the task touches on the idea of recursive and explicit formulas, but it does not provide this terminology
- Resource provides data table to help with organization
- Rubric gives a possible weighting system to determine point values
- Answer key has some inconsistencies (sticks vs. dots) and some incorrect values
