Comparing Data: Graphs and Lists

We Are Learning To compare data in different formats Year 2 Mathematics 45 minutes

Key Vocabulary

Data - information we collect Category - groups we sort things into List - data written in rows Picture Graph - data shown with pictures Block Graph - data shown with colored blocks Most, Least, Equal - comparing amounts

Same Data, Different Ways

Look, Point, Count, Check!

Creating Our Class Data

{"left":"Collect data about favorite fruit from all 23 students\nFirst, make a list on our A3 paper\nThen, create a picture graph with fruit images","right":"Finally, build a block graph with colored blocks\nAnswer questions using all three formats\nUse evidence to support our answers"}

Success Criteria Check
