2nd grade math · Unit 10: Data

What counts as data?

What this lesson shows

A question: which bird visits the feeder most? Data can be photos of each bird, the songs heard, or a count in tally marks. Monday and Tuesday give different counts: data can vary.

The worked example

The lesson works this one step by step: Monday 7, 3, 2; Tuesday 3, 4, 6. Then your kid tries one like it on paper.

The steps

  1. Data answers a question
  2. Pictures, sounds, numbers
  3. Data can vary

Helping at home

Ask what question the counts could answer. Your kid makes a tally chart for both days, then says which bird came most each day. Talk about other data you could collect: a photo or a recording.

If your kid gets stuck

One tally mark for each bird.
