### PRODUCT DESCRIPTION

Mental math (in this case, determining combinations of + and - to produce an elementary equation) is a sorely needed skill in the later grades. The ideal time to foster it is early on. These problems can be used for problem-of-the-day exercises or for competition between students or for a quick drill.

As of 2/9/15 I have made the following revisions to this product:
1. the addition of a moderate difficulty assessment (level 2) with answer key
2. the addition of a more difficult assessment (level 3) with answer key.

Covering 2 skills (subsets of Standards) and the OA domain, these problems can pose a challenge for most students. They are in domain-cluster-standard-skill order where a "skill" is a subset of a standard. Within a skill, they are in difficulty order.

The reason for the 4 sets of problems is that everyone has different needs and different time allotments. So, the shorter worksheets work for some and the longer ones for others.

FEEDBACK ON THE PREVIEW WOULD BE GREATLY APPRECIATED!!!!! THANK YOU in advance.

THE IDEA BEHIND THE ASSESSMENTS IS THAT IF YOUR STUDENTS CANNOT PASS EITHER ONE THEN, MAYBE, THEY COULD BENEFIT FROM THE PRACTICE THAT THIS MINI-UNIT PROVIDES.

THERE IS NO BETTER WAY TO PREDICT MATHEMATICAL SUCCESS IN LATER YEARS THAN IN ENCOURAGING AND FOSTERING MENTAL MATH MASTERY IN THE EARLIER YEARS.

[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. Also, instructional references appear on worksheets but are optional on quizzes.]
