Organization/Institution: DepEd/Nansiakan National High School
Address of Institution: Nansiakan, Kayapa, Nueva Vizcaya
Mobile Phone Number: 09974007651
Rank/Position: Teacher III
Level: Junior High School
Domain: Mathematics: Kalanguya IP Students’ way of adding and subtracting Integers
Nature of IM: Manipulative
Applicability: Heterogeneous group of learners; mostly slow learners
Brief Description:
Experience is the best teacher. The retention of learning is evident if it tickles
students’ interest and they enjoy doing it on their own and or with their group mates.
Tutubong is a kalanguya term meaning to move to one station to another, an
indigenized Instructional Material designed using leftover piece of wood intended to
meet Learning Competency number 6 of the K to 12 Mathematics 7 found in the
curriculum guide which tackle on Performing fundamental operations of integers
particularly addition and subtraction of integers. The physical feature is like a
sungsungka. The holes on both sides of the IM are written with positive at the right
side, negative at the left side, and zero at the middle to represent the sets of integers.
It has a pointer designed using different caricature use to direct and stationary on
the integers which tell the final answer.
