## CodeHS Lessons

Select basic steps to solve algorithmic problems. Problems within these standards can be, but are not limited to, real world problems or problems encountered in the studentâ€™s daily-life. The use of the word algorithm within these standards is applicable to all content areas, not just mathematics. Algorithm within these standards implies a sequence of steps followed when completing a particular task. The steps followed to make a peanut butter and jelly sandwich is an algorithm. Problem solving steps may include, but are not limited to, identifying, stating, and exploring the problem; decomposing a problem into sub problems; examination of sample instances; and solution design, implementation, and testing.
