The Addition Strip Board is used:
To help the child become familiar with basic addition sums.
To help a child practice and begin to memorize addition facts.
To present the commutative property: 9 + 1 = 1 + 9.
To build the consciousness of building to 10 and then adding more.
to practice and memorize unit addition combinations.
This resource includes:
Here you can print your own and go! Save yourself hours of work and lots of money.
This material is suitable for any child – whether in a traditional Montessori environment or not.
Please reach out if you have any questions. I love to receive feedback and always respond when I get some!
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
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.
Apply properties of operations as strategies to add and subtract. If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Fluently add and subtract within 5.
For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
Understand that each successive number name refers to a quantity that is one larger.
Understand the relationship between numbers and quantities; connect counting to cardinality.
