The government approved home-school curriculum used by
AFE is set up so that 7th grade takes a math class for the first 2
trimesters and not for the last trimester.
Adam thought, and I agreed, that it would be a good idea to have 7th
grade continue with some sort of math class for the last trimester so they
don’t get out of the “mode of math”.
What started out as a class I dreaded teaching turned
into one of my favorite classes of the entire year (my physics class was
another favorite). My idea for this math
class at the beginning of the trimester was to incorporate what they learned in
the first two trimesters into “real world” math problems. For example: “Two cars are 500 kilometers
apart and moving toward each other…”.
Needless to say, the kids HATED coming to class.
Then I got the idea to change this math class into a
project class, incorporating math, physics, and engineering principles. I knew this was a successful change within
the first 5 minutes of the very first project.
We did the following 10 projects over the trimester:
1. Tessellations – form unique patterns
without overlaps and gaps by using a combination of shapes, including triangles,
squares, octagons, etc.
2. Building your dream house –
draw your dream house using a scale of 1 cm = 1 foot
3. Velocity Experiment –
calculate the speed at which you run and walk uphill and downhill
4. Parachute Project – build a
parachute with the given materials to slow down a falling object
5. L.1,000,000 Project – spend
L.1,000,000 exactly down to the cent.
6. Bulls-eye Probability – throw
arrows at a target and calculate the probability of hitting each ring
7. Force of friction – find the
angle at which the friction force changes from static friction to sliding
friction for 4 different surfaces
8. Paper Olympics – a 3 part
competition involving paper (tallest tower, longest bridge, furthest flying
airplane)
9. Surface Tension – build an
aluminum boat that can support the most weight
10. Point Load Exercise – apply a
point load to popsicle sticks and construct a graph using Microsoft Excel that
compares the distance between outside supports to the weight required to break
the popsicle stick
At
the end of the trimester, I asked the kids how many of the projects they could
remember without looking at their notebooks.
I was happily surprised when they came up with all 10 projects within 2
minutes. They also had no trouble
telling me the main concept they learned from each project. It is amazing to see how God can use me to
connect with and teach these kids.
