Category sort
Sort a set of observations using one clear rule and explain the categories.
AC9S2I04 • Year 2 Science
sort and order data and information and represent patterns, including with provided tables and visual or physical models
Data becomes easier to understand when it is sorted into meaningful groups, placed in a useful order and represented in a table, sequence or model.
Learning sequence: Collect → Sort → Order → Represent → Describe pattern
Use a clear rule for each category.
Ordering by time reveals a growth pattern.
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning.
Sort a set of observations using one clear rule and explain the categories.
Arrange measurements from smallest to largest or earliest to latest.
Represent a repeating or increasing pattern with a table or physical model.
Key idea: Data becomes easier to understand when it is sorted into meaningful groups, placed in a useful order and represented in a table, sequence or model.
If an answer is uncertain, return to the model and explain what each part represents before calculating or drawing a conclusion.
Read the topic guide and use the teacher slide for instruction. Students can then use the worksheet for written work, open Practice for supported feedback, or take the Test when they are ready.
