Guild Elements and student groups

  • Human Use- edible fruit, nuts, foliage, medicinal herbs, fibers, oils/waxes, wood, etc.
  • Soil Health- cover crops, mulching, decomposers, aerators etc.
  • Insects- some plants can be hosts for beneficial insects such as pollinators. Others can repel harmful insects naturally.
  • Nitrogen/Carbon Cycle- it is important to have a good ration of carbon and nitrogen.  Some plants can increase the amount of nitrogen (fixers) and others help remove it from the soil (scavengers).
  • Water Cycle- certain plants help to retain water in the soil, prevent erosion or create a “micro-climate” to regulate the precipitation in a guild.
  • Detoxifiers- specific plants that purify the air and soil by sucking out harmful chemicals and heavy metals such as mushroom mycelia.
  • Wildlife- plants can create food and habitat for animals or can protect other plants from predators .

Math:
Bits and Pieces 3
4.1-The Product Puzzle
Students explore a product puzzle that shows the existence of multiple strings of numbers forming factorizations for a particular number, 840. The question raised is about finding longer and longer strings.
4-2 Finding the Longest Factor String
Students work on finding the “longest” strings of factors that form a factorization.This leads to breaking non-prime numbers into primes and recognizing that the process ends when all of the numbers in the factorization are prime.The students choose from two strategies to find prime factorizations.They begin to see that not only is this factorization unique, but it can be used to find other information about the number.
4.3- Using Prime Factorizations
Students apply prime factorizations to finding greatest common factors and least common multiples.
