CANADA’S WONDERLAND – Math Grade 7 3
Welcome Grade 7 Teachers to
Canada’s Wonderland’s Math Program!
We have provided you with activities that will take you from your classroom to an action
filled day at the Park. The BEFORE THE PARK activities are set up for your students
to practice some new skills and review some old ones before they go to the Park. The
AT THE PARK activities are a continuation and extension of the classroom activities.
The tasks set up for your students at the Park are designed to let them enjoy all that
Canada’s Wonderland has to offer, while gathering some data to be used back at the
school. The students will use this information to complete a SUMMATIVE
ASSESSMENT that allows them to extend the experiences that they began in the
classroom before the trip. Every activity is completely linked to the new revised
Mathematics Curriculum.
Every activity is designed as a real-world experience. As in the real world, there are
many possible solutions to a variety of questions. We encourage you to challenge your
students to think deeply and reflect on the tasks that are set out before them. We hope
that this experience will be a celebration and extension of your teaching and learning this
year.
Thank you for your on-going support for young people and our programs at Canada’s
Wonderland.

washer attached to it, how many nuts, bolts and washers were used to build Behemoth?
Show all your work.
8. We can use integers to represent rise and falls. For example, if I walk up a set of stairs
it can be represented by +4m. Walking down the stairs would be -4m. Behemoth also
takes you on a series of rises and falls. If the station where you board the train represents
point zero, use integers to describe the ride from when you leave to when you return back
to the station.

Canada’s Wonderland
The Ride of All Rides
The Path to Excitement
Congratulations! You have finished the design of your ground breaking roller coaster,
but your job is only half done. You now need to build a queue area and entrance way to
your ride. These areas have several parts: a tiled entrance, an entrance sign and a fenced
area for the people to line up. You have to make the decisions that will attract the thrill
seekers to your ride.
1. Canada’s Wonderland typically uses rectangular bricks to tile the entrance way to
their ride. Since this roller coaster is going to be The Ride of All Rides, they have asked
you to design an extra special tile. The entrance way is going to be a trapezoid, as seen
below (scale is 1:100).
a) Based on the scale, what are the real-life measurements of the trapezoid entrance?
![Page 45: GRADE 7 MATH - d3knbu6191stae.cloudfront.net · CANADA’S WONDERLAND – Math Grade 7 4 CW Physics, Science & Math Day Activities A correlation with the Ontario Mathematics Curriculum,](https://reader030.fdocuments.in/reader030/viewer/2022040713/5e1949fece76436e3928b733/html5/thumbnails/45.jpg)

b) If the bricks cost $8.75/m2, what will be the total cost to tile the area?
SUMMATIVE ASSESSMENT THE PATH TO EXCITEMENT
2. The company who is installing the bricks has a unique price schedule based on the
pattern you use.
► If you use triangles, squares or rectangles, then you get a 5% discount off the total
price in question 1b.
► If you use any other regular polygon, then you get a 15% discount off the total price in
question 1b.
► If you use a modified polygon (ex. alter an existing polygon through transformations)
then you get a 20 % discount off the total price in question 1b.
► If you use a combination of any 2 shapes, you get a 30% discount off the total price in
question 1b.
a) Use the space below to design a tile pattern that will cover the entire area

2. Answers will vary.
3. Answers will vary.
4. Answers will vary.
5. Answers will vary; however there should be a measured distance and time portion
embedded within the experiment.
6. Some possible answers could include the type of surface, constant speed, wind/air
resistance, experience level, strength etc…
At the Park
1. Behemoth takes approximately 192 sec, or 3.2 min, or 0.053 hours.
2. The average speed is approximately 30.6 km/h.
3. Answers will vary but the top speed is 120 km/h.
4. The actual height is 70 m.
5. Answers will vary, but students should be using the format to find speed as in the
previous question. They could also research the actual heights of rides once they are
back at school.
6. Behemoth is the tallest and fastest roller coaster. Some attractions are taller, such as
Drop Tower; however it is not a roller coaster.
7. 1621m x 8 bolts/m = 12968 x 3 (nuts, bolts and washers) = 38 904.
8. Answers will vary depending on the estimations on the rise and descent each time;
however, negative integers should represent the descent and positive integers should
represent the rise.
So Much Space, So Little Time
Before the Park
1. Answers will vary and the most appropriate unit for the surface area of the classroom
is m2, because cm would result in an extremely large number and km would give us an
extremely small number.
2. Answers will vary.
3. 1.3 km2 = 1 300 000 m

6. Answers will vary; however, triangles can tile any regular polygon (all sides and
angles are equal).
7. Splash Works actually covers an area of 81 000m2.
At the Park
1. The Park has the approximate dimensions of 800m width x 1600m length.
2. Answers will vary.
3. Answers will vary depending on choices from the previous question. It can be found
by (sum of all areas / the number of roller coasters measured).
4. They will likely see some triangles in the support beams while they are lining up.
Some other patterns may be observed as well.
5. In order to prove congruency, we would need the length measurements for each side
and the angle measurements of each side.
6. Answers will vary depending on choices from the previous chart. It can be found by
(sum of all surface areas or volumes ÷ the number of stands measured).
7. Yes, as long as your length, width and height measurements produce the same
product. For example 2m x 1m x 3m = 6m3 and 1m x 1m x 6m = 6m
3.
8. Same as question #7.
Who is the Bravest of Them All?
Before the Park
1. Answers will vary depending on the individual; however, the graph should be close to
a linear pattern.
2. Since it is a linear pattern, we should be able to extend the line and make a relatively
accurate prediction what it will be at 3 min.
3. It is likely that they stopped running at around 90 seconds or at least slowed their pace
because their heart rate levelled off. After 1 min, their heart rate dropped as they were
not exerting as much energy as before. They were likely standing still.
4a) & b) Answers will vary depending on the estimations made.
4c) We can manipulate the data by making the scale smaller or larger, use of 3D bars,
insertion of a break etc…

1. Answers will vary.
2. In order for the sample to be unbiased, it needs to be generated randomly. The larger
the sample size, the less bias and more representative it will become of the population.
3. It is difficult to make the judgement because it would depend on the sample and your
own personal definition of bravery. Students can make a case for youth or adults and
they could both be correct provided it is supported with data.
4. We would have to assume that the sample is representative of the population and
unbiased as well as the factors listed in answer #3.
5. The larger our sample becomes, the more representative it becomes of our population
assuming they are unbiased.
6. Answers will vary depending on their experience. For example, school groups and
students are more likely to be at the Park on a school trip during the day than a large
number of adults because the adults may have jobs/family to attend to.
7. Once school is out and more adults are typically on vacation, our sample could look
very different.
8. Answers will vary depending on their experience. Canada’s Wonderland could use
this data to market their games to a specific target audience. For example, if a lot of girls
are at the basketball game, then the prizes should reflect the target audience to entice
them to play. However, perhaps the boys are not playing because the prizes/games do
not appeal to them.

2. Answers will vary depending on the theme of the ride.
3. Answers will vary depending on the selected side lengths. Ensure that their diagrams
correspond with their charts (1 cm on their paper is equal to 10 m in real-life).
4. Answers will vary; however, a reasonable one is a trapezoid that is not too wide or too
narrow because it will limit the ability of the roller coaster to manoeuvre over the land.
Build it From the Ground Up
1. The ride has to be at least 1296.8 m long (1621m x 0.8=1296.8m).
2. The ride has to be at least 77m tall (70 m x 1.1 = 77m).
3. Answers will vary; however it should be near 1:45 to 2:15.
4. Answers will vary but it should be above 20 km/h (average).
5. Answers will vary.
6. Answers will vary depending on the dimensions and path of their roller coaster.
7. Answers will vary but be sure it meets the minimum requirements. If it does not, we
can make the track longer without increasing the area of land by building the coaster
higher.
8a) - c) Answers will vary but we can calculate the total time by distance ÷ speed. If the
ride is not long enough, they can slow the ride down to ensure it takes longer.
9. Answers will vary. The cost is calculated by length of track (m) x cost/m ($).
10a) - e) Answers will vary.
