Choice Squares 2K17
Activity 1:
The students in Room 8 at Te Paki School wanted to find out which fruits were preferred by class members. Mr Winiata drew some of their suggestions and a ? on the board:Why do you think Mr Winiata drew a question mark?The reason why Mr Winiata drew a question mark is because their were some students who didn’t like the fruits that other students chose. So Mr Winiata put in a question mark.
Each student chose one of the fruits or the ? and drew it on a blank choice square. Jo collected all these choice squares in a box. The students found different ways of arranging the choice squares to displace the results.
Kim made a bar graph like this:

Activity 2:
The students in Room 8 checked their lunchboxes to see what fruit was in them. Jo made this graph of the data.There are only 22 students in Room 8, so why does the graph have 29 squares around the outside?The reason why their is 29 squares outside of the graph is because it is to show how many students have that fruit and, how many people didn’t bring fruit.
B. Does the graph show that the students in Room 8 get their favourite fruit for lunch?The graph only shows how many students have brought their favourite fruit to school. Most people didn’t want to bring a fruit to school.
C. What would you say to Room 8 parents about this data? What I might say to the Room 8 parents and what I think about this data is that, it gave me lot’s of information about how many kids brought fruits to school and how many students didn’t bring fruit at all.

Collecting & Organising Data
Discussion:
Look at this list of vowels. [a,i,e,a,o,u,i,a,u,u] How many are there of each vowel?Because there were only 10 vowels it was easy to work out, but if there were 50 or 100 vowels, how could you work out the number of times each vowel occurred?
Using a tally chart can help.
Example:
Make a mark in the tally column next to the vowel as you go through the list. Remember to mark off in 5’s.
Frequency means ‘how often something occurs’. Add up the frequency column to find out how many vowels there were.
Answer, 30 vowels.
