• Pinpointing random numbers to 100 on a number line
• Visualizing relative values to 100 and transitioning between decades
• For children in grades K-2
• Cardstock number line and tags. Organization labels and blackline masters for replacement pieces included.
• Nine separate exercises with 20 tags each

 (See hundred line instructions.)

Ten strips of ten placed end-to-end to represent 100 - includes tags to designate random numbers:  pinpointing random numbers to 100 on a number line, transitioning between decades, visualizing relative values to 100, preparation for rounding.  (See hundred line instructions.)

Cardstock number line and tags. Organization labels and blackline masters for replacement pieces included. (Lamination recommended for heavy use; cutting required.)  Recommended storage (not included): twelve-inch by three inch plastic sorter for lines; nine hardware drawers, boxes, or envelopes for tags.

Blackline masters or digital downloads for written responses (answer keys included). Recommended storage (not included): file

Scope and Sequence Chart (Click here)

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.
