Hunters

Report
Goal: To create a model of people hunting in the forest
for mushrooms and then start working on improving
their mushroom hunting ability mathematically.

Try doing the following:
Day 1
1. Change the size, color, and shape of your hunters.
2. Change the number of groups of mushrooms, mushrooms in
each group, and radius of the groups.
6. Change the number of hunters.j
Goal: To work on improving their mushroom hunting
ability mathematically.

end
Try doing the following:
Day 2
1. Change the number of hunters to 1, then to 5.
2. Try setting the hunters’ initial heading to 45˚ by using the
command: set heading 45
3. Change each group of mushrooms to have more
mushrooms in a smaller radius.
Try doing the following:
Day 2
4. Have the hunters say “Found one!” using the command:
show “found one!”
5. Instead of turning by -10 to 10 degrees when they haven’t
found a mushroom for awhile, change it to -45 to 45.
6. Change where the hunters start by using the command:
setxy 10 10
Challenge:
Day 2
Have the hunters count how many mushrooms they have
found.
You need to define: turtles-own [counter]
You’ll need to use the command: set counter 0
And every time they pick up a mushroom the command: set
counter counter + 1
Instead of saying show “found one!” have them: show counter
