C. Establishing 1. Lesson Purpose

Lesson Purpose Explain to the learners that the lesson will help them analyze their data to come up
with an accurate conclusion or idea.

2. Unlocking Content Vocabulary

The learners will be given material to read, and they will be asked to take note of
any unfamiliar words, terms, phrases, or sentence, as well as identify confusing ones.
Measurement from measuring instruments and observations produces raw data. As
data usually measures several quantities in different objects, data tends to pile up.
When this happens, searching for data takes a longer time and becomes confusing.
Organizing the data helps us read and use it easily. It also reduces the loss of data and
errors. The teacher will facilitate the discussion by asking the learners to give their

 insights about the material they have read. Then, the teacher will provide additional
information on the cited term, phrase, or sentences.

Understanding The learners will read a story and sing a song titled “Rain Rain Go Away”

Once upon a time, in a faraway land, a sugar family lived in a small house in the
forest. When it was summertime, the three children were happy for they could play
outside. But during rainy seasons, they were all sad and just stared at the window and
sing: “Rain, Rain, Go Away, Rain, rain, go away”.

Come again another day,

All the children want to play,
Rain, rain, go away”. (3x)
