Lead a short class survey with one or two health questions. Record responses together on the board using tally marks.
Answer survey questions, help count responses, and help make tally marks.
Give students a simple graph template. Guide them to add pictures or stickers based on the class data, one picture for each response.
Create a picture graph using the collected data.
Ask partners to discuss questions such as: Which choice has the most? Which has the least? How many students chose this option?
Talk with a partner, point to the graph, and answer questions using complete sentences.
Circulate and ask individual students to read one part of the graph and answer one question orally.
Show understanding by reading the graph and explaining their thinking.
Review the words data, tally marks, graph, most, and least. Ask students to name one thing they learned about the class health choices.
Share one new learning and reflect on the graph.
Students share one fact they learned from the class graph and one healthy choice they noticed was popular.
Students will be assessed through teacher observation, partner responses, and a quick exit question: 'What does our graph tell us about our class?'
