DATA MANAGEMENT - ANALYZING GRAPHS
We're learning how to analyze graphs
Class example
GRAPH ANALYSIS:
This survey is about kids who have a specific type of pet. In the bar graph named Kids Have Pets, I can see that most people have a fish as a pet. None of the kids have a snake as a pet. In this survey, kids had a choice between 6 different animals. This is shown on the X axis. The Y axis tells us how many kids have each type of pet. The scale on this graph increases by 1 each time. The range of data is 8 (8-0=8). There is no option for other types of pets. There were a total of 24 kids who were surveyed. This data could be used for someone who may want to buy a pet or maybe someone who wants to open up a pet store.

Elapsed Time - to the second
MON NOV 27, 2017
Solving Problems with time
20 mins + 5 mins + 1 minute = 26 minutes
26 minutes + 1 hours = 1:26
The amount of time passed is 1hour and 26 minutes

Area & Perimeter - L and T shapes
Area and Perimeter - Problem Solving
1.
The playground at the community centre is rectangular. Its length is 60 m. The
perimeter is 180m. What is the width of the playground? (Show all your work and
draw the figure)
2.The area of Tony’s rectangular garden in 56m. The length of the garden is 8m. What is the width of the garden? Draw the garden and show your calculations.

Area & Perimeter of T and L shapes
- Today we were finding the missing measurements when working with L and T shapes.
- Then we learned how to calculate the perimeter and area of both shapes.
Step 1: Find the missing lengths and widths if you need to. Then split the shape into 2 rectangles
Step 2: Calculate the AREA using the LxW formula for both shape A and shape B.
Step 3: Add the 2 answers from step 2 to get your total area of the shape.
MEASUREMENT - AREA & PERIMETER
We've been learning how to calculate perimeter for rectangles.
Yesterday we learned that rectangles can have the same area but different perimeters (see pictures below
TODAY WE DID SOME PROBLEM SOLVING WITH PERIMETER AND AREA
Our class question:
Lisa is planning to use 48 feet of fencing to enclose her rectangular dog pen.
- there is 48 ft of fencing, this means the perimeter has to be exactly 48 ft
- figure out the largest space with a perimeter of exactly 48 feet
Solving Problems with patterns in tables
Wed. Nov 1st, 2017 - Class question
We are having a fundraiser to raise money for the school. For every car we wash we earn $8.
A)Using a table, show how much money we’d raise if we washed 5, 10, 25, 30, 40 cars.
B) How many cars do we need to wash to raise $650?
***Note: Ms. Hewitt spent $43 on soap and sponges. This needs to be subtracted from the total and then you calculate the $650 raised.
Today's Question: Thurs. Oct 26
John babysits during the week to make money. John charges $8 an hour for each hour that he works.
How much does John earn when he works for 3 hours? 8 hours? 12 hours? Show your work using a table.
- you can multiply the term # by 8
b) Write the pattern rules?
Start at 8, increase by 8 each time (term)
The relationship between the term # and term = term # x 8
c) Use the patterns to predict how much he will earn working for 21 hours.
d) John saves all his money he earns because he wants to buy a mountain bike. The bike costs $250 to buy. How many hours does John need to work to buy the bike?
