- Manipulative exercise that gives upper elementary and middle school students exposure to set theory
- Helps develop logic, attention to detail, and pre-algebra skills
- For children in grades 4-8
- Colored cardstock manipulatives comprised of long strips with Venn diagrams and corresponding cutouts
- Eight separate exercises, each with about 10 responses
Small cards that be manipulated for more challenging cumulative exercises on set theory: elements, cardinal number, empty set, union, intersection, Venn diagrams.
Colored cardstock manipulatives comprised of long strips with Venn diagrams and corresponding cutouts. (Lamination recommended for heavy use; cutting required.) Recommended storage (not included): Long pieces in 9 inch by 3 inch plastic organizer; cut-outs in 8 hardware drawers, boxes, or envelopes
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.
