Intervention Ideas and Materials for K-2 Numeracy and Multiplication

Do you need ideas and materials to implement effective math interventions? The Flip Flop Teacher Toolkit and Multiplication Game Decks are invaluable during intervention time. Activities can be differentiated quickly and easily to meet the individual needs of a student or small group.

There are a number of videos included with the explanations below to help you get started with your math interventions. There are many ideas included on the Intervention page as well as other pages on our website at

(Numeracy Concepts and Skills for K-3rd Grade)

Here is a list of numeracy concepts and skills the Teacher Toolkit and Multiplication Decks provide practice with. These are numeracy concepts and skills from the Common Core Math Standards and other math research.

Kindergarten Concepts and Skills:

  • Recognize and write numerals
  • Understand the relationships of more, less, and the same
  • Subitize numbers up to 5 (recognize up to five objects automatically without counting)
  • Combine and partition 5 (know the combinations that equal 5: 1 and 4, 2 and 3, etc.)
  • Count within 100 by ones and tens
  • Fluently add and subtract within 5
  • Gain a foundation of basic place value of numbers 11-19

First Grade Concepts and Skills:

  • Count forward and backwards by ones, tens (on and off decade), fives, and twos
  • Know one and two more, one and two less of a number
  • Recognize spatial patterns and relationships up to 10 (recognize up to 10 objects in spatial patterns)
  • Combine and partition numbers up to 10 (including five plus, doubles, and near doubles)
  • Combine and partition 10 (know the combinations that equal 10: 1 and 9, 2 and 8, etc.)
  • Fluently add and subtract within 10
  • Understand place value of tens and ones

Second Grade Concepts and Skills:

  • Combine and partition numbers up to 20 (including 10 plus, 9 plus, doubles, and near doubles)
  • Work with equal groups of objects to gain foundations for multiplication
  • Understand place value of hundreds, tens, and ones
  • By the end of second grade, students need to be able to “fluently add and subtract within 20 using mental strategies and know from memory all sums of two one-digit numbers.”*

Third Grade Concepts and Skills:

  • Use multiplication and division within 100 to solve word problems in situations involving equal groups and arrays
  • By the end of third grade, students need to “know from memory all products of two one-digit numbers.”*

Math Path for Structuring Numbers

(Combining and Partitioning Numbers to 20)

>>> Click here for Math Path for Structuring Numbers Details <<<

Math Path for Structuring Numbers up to Ten:

  • Subitizing
  • Combinations of 5
  • 5 and Some More
  • Combinations of 10
  • Doubles to 10
  • Doubles to 10 (Plus 1)

Math Path for Structuring Numbers up to Twenty:

  • 10 and Some More
  • Doubles to 18
  • Doubles to 18 (Plus 1)
  • 9 and Some More
  • Combinations of 20

Throughout the year, I will identify students who need extra support in math. Sometimes, I will do a small group intervention daily for 15 to 20 minutes on a few specific, focused concepts/skills students need to help them progress. Other times, I will choose one or two students and do a Quickervention. That is an intervention that I do throughout the day for short periods of time. I will meet with a student several times a day for one to three minutes each time.

When doing interventions or Quickerventions, I assess students to find out what concepts and skills they need to move them along in their math development. I use both Math Paths listed above to help determine what concepts and skills students are missing. Then I choose specific, targeted skills to work on and progress monitor frequently.

The following information and videos can help you get started with a wealth of quick, easy interventions or Quickerventions.


Quickervention Station

Sometimes I choose to do a four to six week intervention with a small group. Other times I do what I call a Quickervention with one or two students instead. I have found that short one to three minute focused activities several times a day work well. To see how I set up my Quickervention Station in my classroom, click here.



Subitizing and Exploring Combinations of 5

For some quick activities to explore subitizing and combinations of 5, click here.

These activities can easily be adapted to other Math Path skills. Our Flip Flop Math materials and activities provide students with explorations with both types of subitizing: perceptual subitizing (recognizing small groups of objects usually up to 5 without counting) and conceptual subitizing (combining small groups and seeing them as units). For more information about subitizing, go to our Home Page at and read, Should You Teach Subitizing?

You can adapt the activities for combinations of 5 to five and some more, combinations of 10, and combinations to 20. Just change the frame from a five frame to a ten frame or a twenty frame or a double ten frame and change to a polyhedral die. Use the corresponding bead rack and dot cards.


Exploring Small Doubles

For some quick activities to explore the small doubles, click here.

You can also explore the larger doubles using the twenty frame.


Exploring Combinations of Numbers Up to Twenty

For some quick activities to explore combinations of numbers up to twenty, click here.


Exploring One More and One Less

This video shows a game to explore one and two more and one and two less using the Game Board in the Flip Flop Teacher Toolkit.


Recognizing and Sequencing Numbers

For quick activities to explore recognizing and sequencing numbers, click here.

These activities can be adapted for counting by ones, tens, fives, twos, and other multiples as well as counting backwards. You can also play the games Say, Sort, and Sequence and Switch by creating game decks to meet the needs of your students. For instance, if your students need work on recognizing and sequencing teen numbers, the Flip Flop Teacher Toolkit has four sets of those numbers in four different colors. If a student needed to practice sequencing numbers that cross the decade, you could create a deck with four different rows with numbers in order that cross the decade such as 27-32, 47-52, 67-72, and 87-92. Go to Flip Flop Games and watch the videos to see how to create a deck, how to play Say, Sort, and Sequence, and how to play Switch.


Exploring Multiplication

The Multiplication Game decks can be used for practice with conceptual subitizing. To learn more about that, go to to read the article, Should You Teach Subitizing?

The following video can help you get started with some activities for exploring beginning multiplication.
