Assess the predominant ethnographic breakup of students in the classroom. Determine how they are tied to the local community. As an example, determine whether they listen to their elders in the cultural context or have specific role models within the community.
Develop visual mathematical word problems that can be connected to tasks performed in the students' communities.
Break the students up into pairs, and have them work on solving a word problem. As an example, provide each pair with a piece of string and have them create a rectangle.
Move around the classroom, and ask students questions to determine if they have thoroughly understood the concept.
Record video of community role models performing a task that can be analyzed mathematically. This could include building a variety of structures. Teach mathematical concepts using the video as an example in class.
