Teacher's field guide

What Students Need to Do: Students examine simple tables, tally charts, picture graphs, measurements, or recorded observations. They identify repeated results, changes, highest and lowest values, and details that stand out.
What Mastery Looks Like: A student can name at least two notable results from a small data set. The student supports each statement with specific counts, measurements, or observations.
Common Misconceptions: Students may focus on colors or pictures instead of the values shown. They may describe one result as a pattern, misread the graph scale, or make a claim without using data.
How to Assess It: Give students plant heights of 3 cm, 5 cm, and 7 cm over three weeks. Ask, “What changed, and which numbers support your answer?”
