Alberta Education has developed a set of hands-on tasks to assess problem solving and communication in mathematics. Students circulate to six stations that contain hands-on materials: Seating Place (numeration, analysis, use of model); Highway to Mathematics (measurement, application); Solar Cylinder (geometry, application, analysis, synthesis); Ski Jumping (graphing, numeration, data collections, analysis, interpretation); Bucket of Beans (measurement, estimation); and Packaging (numeration, analysis, monitoring). It takes about one-and-one-half hours for students to complete all the tasks in the circuit. The same performance criteria are used for all performance tasks.

• Grade 9 Task - Bucket of Beans
• Performance Criteria

Problem:

Estimate the number of beans in the bucket.

You should have:

large bucket of beans magic markers tray small cup

Instructions:

Using any estimating strategy or population sampling techniques, estimate the number of beans in the bucket.

NOTE: Leave the station in the same arrangement it was set-up originally.

1. Explain the strategy you used to estimate the number of beans.

2. About how many beans are there in the bucket?
