SUBJECT:
Math First Grade
TEACHERS:
LeAnn Jack; Lauri Lonon
STANDARD:
 1.OA.1 Use addition and subtraction within 20 to solve word problems involving situations
of adding to, taking from, putting together, taking apart, and comparing with unknowns in all
positions, e.g., by using objects, drawings, and equations with a symbol for the unknown
number to represent the problem
 1.NBT.1 Count to 120, starting at any number less than 120. In this range, read and write
numerals and represent a number of objects with a written numeral.
OBJECTIVE (EXPLICIT):
 Use addition to solve word problems using manipulatives (cubes)
 Write an addition equation
 Identify the symbols of an addition equation
EVIDENCE OF MASTERY (MEASURABLE):
BEFORE
SUB-OBJECTIVES, SWBAT (SEQUENCED FROM BASIC TO COMPLEX):

KEY VOCABULARY:
MATERIALS:
Add, equation, altogether, addends, sum
Cubes
White board or paper (individual)
Story cards

TEACHER WILL:
STUDENT WILL:
Say: A child had 2 red apples and 3 green
 Orally answer the questions
apples. How many apples does the child
 Students guide teacher through
have?
models using cubes.
Ask:
 How many apples are red?
 How many apples are green?
 How many apples are there together?
How do you know?
 How many cubes would you start with?
Why?
 How many cubes would you add? Why?
 When you put the cubes together, how
many cubes do you have altogether?
 How would we write an addition
equation to represent this story
problem?
Provide additional examples if needed
DURING
CO-TEACHING STRATEGY IF APPLICABLE
TEACHER WILL:
Explain activity:
In partners, one student will choose a word
problem card from a pile and read it to their
partner. The other student creates an equation
using cubes. Both students write equation on
white board/paper.
Each student takes turns as the reader.
STUDENT WILL:
 use cubes to represent story
 count how many cubes they have
altogether
 write equation on white
boards/paper
AFTER
CO-TEACHING STRATEGY IF APPLICABLE
TEACHER WILL: Ask:
 What does it mean to add?
 What symbol do we use to show
addition?
 What does altogether mean?
 What is an equation?
Say:
 The numbers that are being added
together are called addends
Ask:
 What numbers in the equation would be
the addends? (refer to first sample)
 What symbol do we use to show equal?
Say:
 A sum is the answer to an addition
equation.
Ask:
 What is the sum in the equation?
Say:
 Write a sentence to tell what an addition
equation is using the words/phrases:
putting together or combining,
addends, and sum.
 Draw a picture of a story problem and
write an equation to match the picture.
CO-TEACHING STRATEGY IF APPLICABLE
STUDENT WILL:
Partner Share:
 Adding means putting together or
combining or getting larger
 Show partner an addition symbol
using fingers
 Altogether means putting things
together, combining, or getting
larger
 An equation is a set of numbers and
symbols that equal
 The numbers 2 and 3 are the
addends
 Show partner an equal sign using
fingers
 The sum is 5
Math Journals:
 Write: An addition equation is
putting together addends to find a
sum.
