Common Core Standards:
CCSS.MATH.CONTENT.1.OA.A.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.
CCSS.MATH.CONTENT.1.OA.C.5 Relate counting to addition
and subtraction (e.g., by counting on 2 to add 2)
CCSS.MATH.CONTENT.1.OA.D.7 Understand the meaning of
the equal sign, and determine if equations involving addition and subtraction
are true or false. For example, which of the following equations are true and
which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Targeted Needs of Student:
Practicing
addition, different ways to show an equation, working with equations, visual
representation of addition
Goal:
Providing
students with practice adding simple
equations
Materials Needed:
1. Construction paper
2. Scissors
3. Staples
4. Sentence strips
Explanation/Summary:
Students
will make paper chains to show simple additions problems. They will show the
first number that is added with one color and then the other number to be added
with another color. Then, students will connect the chains and count the total
number to show the sum of the numbers. At the bottom of the chain, students
will attach the equation written on sentence strips and then also write the
equation in circles to show how they added (see the picture below.)
