Number relationships provide the foundation for strategies that help pupils remember basic facts. Throughout mathematics in Kindergarten-Grade 2, students develop numerical fluency with conceptual understanding and computational accuracy. A Grade 1 standard in the K to 12 curriculum in Mathematics is “compose and decompose numbers.” This basically means to break a number into as many sets as possible, such as: 8 can be eight groups of one, two groups of four, a group of eight and a group of zero, a group of seven and a group of one, and so on. Basic number sense is used to compose and decompose numbers in order to solve problems requiring precision, estimation, and reasonableness.
The following is a lesson plan on teaching “composing and decomposing numbers” using the Cebuano and Ilonggo language. This is hoped to help teachers who are using their mother tongue in teaching this topic.The lesson plan is using Cebuano or Ilonggo language in the discussion of the lesson although it retains the English translation.
Grade level: 1
