Grade Level:
  • 6th Grade

Subject Area:
  • Mathematics

Procedure:

The instructor should familiarize themselves with the Thinking Block Ratio applet prior to introducing the activity. Work through a few levels to establish an appropriate level of expectation for each of the students in the classroom.

Note: some of these websites require Flash Player so you will need to use Firefox or Safari browsers to view them (not Chrome).

 

Activity 1

Students can quickly demonstrate their basic understanding of ratios by working through problems on the Ratio Game. Students should not move to activity 2 until they are able to meet with success on this interactive.


 

Activity 2

Watch the video tutorial for Math Playground Thinking Block Ratios, ideally projected for whole group viewing. Demonstrate an additional problem with the whole class. Allow each student to begin Thinking Block Ratios. Students should work through the five problems at each level.

Students will need to read the questions carefully as they move through the levels of difficulty. This is a great activity to build conceptual understanding of ratios.

Standards:

6.RP.1 Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

6.RP.3 Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagramsG, double number line diagramsG, or equations.
