• pattern blocks

• connecting cubes

• counters

• combination of the blocks, cubes, and counters

• sets of books

Students then show their representation to a partner and ask questions that can be answered about their collection of objects.

Create collections of 10–20 objects with up to three attributes by which to sort.

## Stage 2: Picture or Bar Graphs

Students sort 20–30 objects into three categories and make a picture or bar graph that shows how they sorted. Provide students with a group of items that will be interesting for them to work with such as:

• pattern blocks

• counters

• combination of the blocks, cubes, and counters

• sets of books

Students then ask their partner two questions that can be answered based on their graph.

Create collections of 20–30 objects with up to three attributes by which to sort.

## Stage 3: Scaled Graphs

### Narrative

Students sort 40–100 objects into 3–5 categories and make a scaled picture or bar graph that shows how they sorted. Provide students with a group of items that will be interesting for them to work with such as:

• pattern blocks

• connecting cubes

• counters

• combination of the blocks, cubes, and counters

• sets of books

Students then ask their partner two questions that can be answered based on their graph.
