Objectives must be met over the week and connected to the curriculum standards. To meet the objectives,
necessary procedures must be followed and if needed, additional lessons, exercises and remedial activities may
be done for developing content knowledge and competencies. These are assessed using Formative Assessment
strategies. Valuing objectives support the learning of content and competencies and enable children to find
significance and joy in learning the lessons. Weekly objectives shall be derived from the curriculum guides.

These steps should be done across the week. Spread out the activities appropriately so that students will learn
well. Always be guided by demonstration of learning by the students which you can infer from formative
assessment activities. Sustain learning systematically by providing students with multiple ways to learn new
things, practice their learning, question their learning processes, and draw conclusions about what they learned in

generalizations
and abstractions
about the lesson
Abstraction:
Estimation refers to the
process by which one
makes inferences about a
population, based on
information obtained from
a sample.
A point estimate of a
parameter Ѳ is a single
value/number that can be
regarded as a sensible
value for Ѳ
A point estimate is
obtained by selecting a
suitable statistic and
computing its value from
the given sample data.
The selected statistic is
called the point estimator
of Ѳ.

Interval estimation is the
use of sample data to
calculate an interval of
possible values of an
unknown population
parameter, in contrast to
point estimation, which is
a single number.
An interval estimate is
defined by two numbers,
between which a
population parameter is
said to lie.
Ex. a ≤ μ ≤ b x1
≤ σ2 ≤ x2

V. REMARKS
VI. REFLECTION
Reflect on your teaching and assess yourself as a teacher. Think about your students’ progress this week. What
works? What else needs to be done to help the students learn? Identify what help your instructional supervisors
can provide for you so when you meet them, you can ask them relevant questions.
