Addition ,Subtraction And Differentiation

STEM Unit Plan Template
Week 1 Day 1 Day 2 Day 3 Day 4
Lesson Title Addition and
Subtraction.
Differentiating
10, 100 and 1000
as groups of 10.
Use addition and
subtraction for
measuring length
Practice day for
testing counting
and measurement.
Brief Summary
and Rationale
Here the students will
be learning about how
to use addition and
subtraction to and
from a number to
reach another number.
Addition and
subtraction are
primary requisites for
financial numeracy
development. It is
therefore also
identified in the state
standards.
Here the students will
learn about how 100
and 1000 are just
groups of 10.
Understanding group
based counting allows
the student to count
faster and easier. This
develops counting
based numeracy skills
in significant ways.
Here the students will
implement their
knowledge of addition
and subtraction in the
context of measurement.
They will add numbers
to existing lengths to
measure the difference
in lengths.
The students will reflect
upon their engagement
in the past three days
and successfully
implement their learning
in a practical context.

Learning
Objectives
Students will be
able to learn
about and use
addition and
subtraction from
between 1 and
100 to solve one
and two step
word problems.
They will
represent the
problem in an
equation format
with a symbol for
the unknown
answer.
Students will
understand that
the numbers 100
and 1000 can be
reached by
grouping 10s
together.
Students will
count numbers of
different digits
using knowledge
of counting by
10s.
Students are able
to use a ruler or a
yardstick to
measure lengths.
Students use
addition and
subtraction to
count the units of
measurement.
Students can
count, add and
subtract to fill
worksheets to
display theoretical
understanding.
Students can
display
appropriate
knowledge about
Digital device use
by practicing
interactive
counting tasks.
Vocabulary and
Academic
Language
Vocabulary will be
suited for 2nd grade
students, meaning not
too many complicated
words and sentence
structure. Academic
language will include
mathematical terms
like addition and
subtraction, numbers,
plus, minus, equal to
etc.
The vocabulary will be
simple and the
academic language will
include words like ten,
hundred, thousand, ten
thousand etc.
The vocabulary will
include words like the
units of measurement
(e.g. inch, foot, yard,
mile) and also the United
States customary
system (USCS).
Academic language will
involve appropriate
connections between the
measurement units and
counting systems.
This is a testing day
where the students
knowledge will be tested
with appropriate teacher
support. The vocabulary
will include all the words
that are used in the
context of teaching
counting and
measurement.
