- "All Reals" is fourth and last interval set stressing continuous positive and negative values including fractions.
- All real numbers as continuous points that can be represented on a number line.
- For students in grades 5-8
- Blackline masters for written responses (answer keys included).
- Ten separate pages; typically two pages comprise one exercise.
Verbal, algebraic, and number line expressions depicting all positive and negative values including fractions: incremental introduction of continuous positive equalities and inequalities, including fractions. Younger students may do as match, while older student do abstractly and use "match" as a check. Students often do two exercises at a sitting.
Blackline masters for written responses (answer keys included). (No special preparation required.)

The teacher's experience and the sequence of skills in the students' basic math program are the best guides in determining which skills should be introduced first. In general, the scope and sequence chart above can be used as a guide.
A number of sets for younger children are "color coded." Some teachers present all the levels with an exercise set, while others prefer to present all the blue (two-digit) exercises, progress to the pink (three-digit), and culminate with the green (four-digit).
Other skills such as Roman Numerals require no prerequisites other rhan an understanding of place value. Such exercises can be presented any time.
