Students will launch the investigation by collecting class favorites data, building an initial picture graph, and using early addition and subtraction comparisons to ask what the data shows. They will also explore how shapes and fair shares can help design the class display with a community partner, then record a first reflection about a math idea, a strategy, and a challenge.

Students will study a puzzling class favorites dataset, ask investigable how many and how many more/less questions, test ways to count and record information, and build a peer-reviewed plan for collecting data accurately with charts, drawings, and addition or subtraction within 20.

Students will collect class favorites data, count and verify totals with ones and tens, record evidence in tally charts and picture graphs, and complete a midpoint quality check that shows their data displays match their counting records. They will use partner critique and weekly reflection to revise for accuracy, clarity, and evidence.

Students will analyze their class favorites evidence, use addition and subtraction within 20 to explain graph patterns, compare results to their earlier question and hypothesis, revise gallery explanations through peer feedback, and prepare clear visitor-ready math talks with reflections that name strategy, challenge, and next-step thinking.

Students will present their favorites-and-choices investigations to visitors, explain how their graphs, equations, and models answer real classroom questions, and complete a final reflection showing strategy use, revision, and growth.
