Daily math intervention should focus on developing students' number sense, and should happen in addition to the student's regular math block. A typical 30-minute intervention block should include the following components:

• Warm-Up

• Number Sense Development

• Word Problem

In addition to the above components, math games should be used frequently, and can replace any of the 3 other components on a given day.

The CRA model (i.e., Concrete, Representational, Abstract) should be closely followed, especially during the Number Sense Development and Problem Solving phases of the intervention.

Warm-ups should take 5-10 minutes, and can cover a variety of math concepts (e.g., geometry, number sense, etc.). It is sometimes helpful for the warm-up to be related to the math unit/strand that students are studying in class (e.g., geometry, time, money, etc.). Some examples include:

Number sense development should take approximately 10 minutes, and should happen every day in some form. Rekenreks, counters, place value charts, Cuisenaire rods, base 10 blocks, and hundreds charts are all essential tools for number sense interventions.

Building students' confidence with problem solving is an important component of intervention. It is also the primary manner in which students connect the number sense skills they're developing to real-life contexts. Problem solving should take 10-15 minutes, and be within the students' zones of proximal development.
