M2.7.1 For the adult
Tally and frequency tables
My friends all shout their answers at once. How do I keep count?
What this chapter teaches
A tally counts as answers come in: one stroke for each answer, and the fifth stroke crosses the other four. The number in each row is its frequency, and the frequencies add up to the number of answers.
Three questions to ask
There is no one right wording. Listen for the idea.
- Why do we cross the fifth stroke in a tally?
- How can you check that a frequency table is complete?
- Ten friends choose a colour. How would you keep count while they shout?
After the chapter, the learner can
- Record data in a tally and frequency table
- Find totals and differences from a frequency table
What they copy into their notebook
Draw one stroke for each answer. Cross the fifth stroke. The number in each row is its frequency. Add the frequencies to get the total.
