THE OVERALL PURPOSE OF THIS ENTIRE PRODUCT IS TO GIVE YOU IDEAS AND INSPIRATION IN TEACHING TOPICS IN DOMAIN OA at the various grade levels. These problems were developed by me over the course of 9 years in teaching remedial and gifted math. Actual units with multiple problem sets with teaching guides and several quizzing options are also available.
1. An outline of all 2,488 problems (as of 2/18/16) within over 60 different skills. Many of these skills (with attached problems) are in use at my school in actual courses.
2. 2 worksheets (with answers) of level 1 (elementary) and 2 (requiring more thought but often accompanied by instructions) difficulty.
3. 2 worksheets (with answers) of level 2 (requiring more thought but often accompanied by instructions) and level 3 (more challenging) difficulty.
4. 2 worksheets (with answers) of level 3 (more challenging) and level 4 (most challenging) difficulty.
The Preview is limited to some Grade 3 problems.
[The problems in All WORKSHEETS and PREVIEWS are printed in difficulty (1 [easy], 2 [not so easy], 3 [proficiency] up to 4 [mastery]) order within a skill. The actual difficulty level appears slightly to the left of the DK box of each problem in a very small font.]
