Math Intervention Programs (K-5) - FREE

 Number line fluency is one of the earliest indicators of math success. If your students need more than games to build this skill, our Primary Numeracy Intervention Program includes sequenced lessons that take students from concrete number line work all the way to mental computation — and you can try part of it completely free.

• The Unlimited Number Line gives teachers a flexible tool for demonstrations, problem solving, and guided practice. It allows students to visualize mathematical concepts on a dynamic number line.
   
• Number Line Battleship challenges students to identify missing numbers on the number line, encouraging estimation skills and reinforcing number placement.
   
• The Covered Number Line builds on the Battleship format but allows teachers to create and control the specific questions, providing greater adaptability for instruction.
   
• The Ordering and Sequencing Game focuses on arranging numbers in the correct order on a number line, supporting students in understanding number sequences, counting, and place value.
   

These number line games offer a variety of approaches for teaching and practicing essential math concepts while keeping students actively engaged in reasoning with numbers.

These games practice the strategies — but knowing which strategy to teach, in what order, and how to scaffold it for a struggling learner is the harder part. Our K-5 Intervention Programs give you that complete sequence, from counting on all the way through multi-digit operations. Part of it is free to try with no commitment. [See the Free Program →] 

• Frog Subtraction and Sausage Subtraction emphasize the counting-back strategy, helping students strengthen basic subtraction skills.
   
• Hidden Counters introduces the part–whole relationship, encouraging students to see how numbers can be composed and decomposed in different ways.
   
• Doubles and Break Apart move students into more advanced strategies, building efficiency with both addition and subtraction through pattern recognition and flexible thinking.
   
• Double Digit extends practice to two-digit addition and subtraction, reinforcing place value understanding and multi-step reasoning.
   

These addition and subtraction games are designed to gradually build student understanding, from foundational counting skills to more complex strategies that prepare them for higher-level math concepts.
