# Stage 1 - data – tally marks

## Activities to support the strategy

### Tally tables

#### Modelled

• Teacher conducts survey (choose topic to suit class interests)
• Explain tally marks (one for each vote; look at what happens at every 5th vote)
• Look at the amount of categories students could choose from, discuss what would happen if too many or too few categories were available
• Explain every student must vote, but only once
• At the end of the survey, count the tally marks (as a class) and make sure it represents the amount of students in the class
• Discuss as a class what they notice about the survey E.g. which is the most popular, least popular, how many votes in a given category etc.

#### Guided

• Get students to select their own topic to survey (give some ideas)
• Give instructions on how to lay out their tally table (give between 3 and 5 possible categories, remind why too many or too few categories are ineffective)
• Allow time for students to survey other members of the class (each student must vote, but only once)

### Independent

• Students to count tally marks and make sure they match the amount of students in the class
• Students to look at the results of the survey and pose questions that can be answered by looking at their tally table
• Working in pairs, student 1 is to cover their survey categories and quiz student 2 with the questions they have already developed about their tally table
• Students to swap roles

### Reflection

• Class discussion looking at what questions were easy to answer, which were difficult to answer, which couldn't be answered by looking at the graph
• Students to reflect on other uses of a tally table
• Students to reflect on other questions that could have been posed

### Extension

• Use the tally table to create a column graph and picture graph.
