Study guide: Weather records and careful claims
Read, sort, compare, and explain a small weather record.
Ideas to explain in your own words
- Use recorded observations to describe what happened.
- Group recorded days by a stated weather label.
- Notice whether two recorded observations match.
- Separate a recorded observation from a guess about later.
Watch your reasoning
- Monday and Wednesday are sunny. Counting those two entries gives two sunny days. Tuesday is rainy and is not part of this sunny-day count.
- Days 1 and 3 both say cloudy, so the cloudy group has two entries. The record has no snowy entry.
- Wednesday is labeled rainy at both recorded times. Tuesday changes from sunny to cloudy.
- The Friday note explicitly says rainy. The record says cloudy on Thursday and gives no Saturday note.
A worked review example
Read a Tiny Weather Record: In a two-day record of Monday rainy and Tuesday rainy, there are two rainy days. Both entries have the rainy label. Sort Days by Their Weather: The cloudy group has days 1 and 3: two days. The rainy group has day 2: one day. The sunny group has day 4: one day. 2 + 1 + 1 = 4 entries. Compare Two Times on One Day: For Tuesday, sunny and cloudy are different labels. For Wednesday, rainy and rainy match. Two matching notes do not tell us every moment of the day. Say What the Notes Support: “Friday was recorded as rainy” has evidence: the Friday entry. “Saturday must be rainy” has no Saturday observation and is not certain from this record.
Make a practice plan
- Try the supplied lesson problems without looking at the answers.
- Compare your method with the worked examples and explain any correction.
- Use the new review cases, then complete the transfer task on paper or in your own document.
