## Research-Based Ten Frames and Dot Patterns to Ten Flashcards

The purpose of this comprehensive research-based set of 86 flashcards is to help students increase their numeracy skills by strengthening their ability to subitize, recognize spatial patterns, and develop part-part-total learning for numbers to ten.

The flashcards include specific dot patterns for subitizing and spatial pattern recognition based on research from the following three resources:

## Resource A:

In the book, How the Brain Learns Mathematics, by David A. Sousa, 2008, information by Clements (1999) suggested four guidelines to follow when designing activity cards to encourage subitizing. The group to be subitized should:

• Stand alone and not be embedded in pictures
• Be simple forms, such as groups of circles or squares rather than pictures of animals
• Emphasize regular arrangements that include symmetry
• Have strong contrast with the background

## Resource B:

In the book, Elementary and Middle School Mathematics, by John A. Van de Walle, 2004, the author suggested a set of dot patterns to help students recognize quantities up to 10 without the routine of counting.

## Resource C:

In the book, Developing Number Knowledge, by Robert J. Wright, et al, 2012, the authors suggested a progression of introducing ten frames to provide instruction on structuring of numbers 1 to 10.

The flashcards are organized to support the following numeracy concepts:

• Subitizing and recognizing spatial patterns to ten
• One more and two more of a given number to ten
• Partitions of five
• Five as a reference (five-wise) to ten
• Pairs as a reference (pair-wise) to ten
• Partitions of ten

The majority of the dots on the cards are blue and some of the cards also have red dots to support part-part-whole learning, so you will need to print them in color. There are four flashcards per page. After cutting, they measure 5.5″ by 4.25″. For quick and easy access, the flashcards are organized by a small colored frog in the corner with a key indicating which set they go with. I printed my set on 8.5″ by 11″ 110 lb. white cardstock.

• 44 regular and irregular dot pattern cards to ten
• 11 five frame cards (including amounts up to 5 and partitions of 5)
• 13 ten frames organized five-wise
• 7 ten frames organized pair-wise
• 2 ten frames organized both five-wise and pair-wise
• 9 ten frames organized by partitions of ten
• A research-based path to follow for presenting the concepts
• A set of directions and activities

By purchasing the Research-Based Ten Frames and Dot Patterns to Ten Flashcards electronically, a teacher is allowed to make sets of the flashcards for use in his/her classroom each year. Please respect our copyright and only print copies for your class. If other teachers or parents would like to use the flashcards, encourage them to purchase their own copy. Our company wants to continue to provide versatile and easy-to-use materials for teachers, and we need your support.

## Organization Ideas:

Here’s what I did to organize my Flashcard set. I punched holes in the upper left hand corner of each card. Now I can group them in a variety of ways. I can use the code on the cards and group them that way, or I can pick a more specific grouping such as:

• Subitizing up to 5 objects
• Combinations of 5 or 10
• One more than a number
• Two more than a number
• Doubles
• Near Doubles
• Five and some more

I use rings to group them and then combine all of them on a larger ring. Then I have easy access to the Flashcards in an organized way and can differentiate quickly between individuals.
