Step 1

Choose a Format

OPLET makes it easy to create tailored resources for your math team. With just a few steps, you can create any of the following:
  • Worksheets
  • Flash cards
  • Problems of the Day
In our example to the right, our OPLET user, Anita Solve, has decided to create a worksheet for her Mathletes.

Step 2

Select the Number of Problems

After choosing a format OPLET users select the number of problems (1-30 for worksheets and flash cards; 1-10 for Problems of the Day) to include. They also write the title and have the option to leave a space at the top for students to write their names.
 
In our example to the right, Anita Solve has decided to give her worksheet the title "Algebra Jumble," and it will include 8 problems, with no space for student names.

Step 3

Select the Types of Problems to Include

Next OPLET users can select the problems to include in their resource, based on solution availability, math concept, MATHCOUNTS usage, difficulty level and year the problems were used in the MATHCOUNTS Competition Series.
 
Solution Options: choose problems from the entire OPLET database or only those that have a step-by-step solution (all problems come with an answer key).
 
Math Concept: Algebra, Arithmetic, Counting & Probability, Geometry, Number Theory, Prealgebra, Other or a random sampling.
 
MATHCOUNTS Usage:
  • Standard problems without calcuator usage (Sprint Rounds and Warm-Ups)
  • Standard problems with calculator usage (Target Rounds and Workouts)
  • Team problems with calculator usage (Team Rounds)
  • Quick problems without calculator usage (Countdown Rounds)
  • Random sampling
Difficulty Level: from 1 (Easy) to 5 (Difficult), or a random sampling.
 
Year Range: from 1990-2017 in 5-year blocks of time, or a random sampling.

Step 4

Review Selections

Before creating a worksheet, flashcard or Problem of the Day, OPLET users can review the selections they have made.
 
In our example to the right, Anita Solve reviews the worksheet she is about to create, with problems from the entire OPLET database, that cover algebra concepts, are standard problems without calculator usage, are varying levels of difficulty and from the years 2010-2013.

Step 5

Choose How OPLET Will Extract Problems

The last step to creating a personalized resource in OPLET is to decide how OPLET will select problems for your resource. After providing their specifications in previous steps, OPLET users have the following options:
  • Let OPLET select the problems at random.
  • Have OPLET generate a pool of problems so you can choose each problem manually.
  • Choose each problem manually, and have OPLET include particular problems you have previously generated in the pool of problems.
Once the resource has been created, the OPLET user can download a PDF of the worksheet, flashcard or Problem of the Day, plus a separate PDF with the answer key and solutions for those problems that include them.
 
In our example to the right, Anita Solve has decided to let OPLET choose the problems at random. Now Anita is ready to see her completed worksheet created by OPLET!
OPLET FAQ

How many problems and solutions does OPLET contain?

Approximately 15,500 problems from previous MATHCOUNTS School Handbooks and competition. All of these problems include answers, but only about 6,500 problems include step-by-step solutions.
 

Can I select problems from a specific competition or handbook?

No, you will not be able to, for example, extract the entire 2007 Chapter Competition or select individual problems from that competition (i.e., Sprint Round #12). But, you can elect to include only problems from a specific 5-year range, problem type and difficulty level.
 

How much does an OPLET subscription cost and can I get a discount?

A 12-month subscription to OPLET costs $275. Coaches who have registered their school for the Competition Series can receive a discount of $5 per student (up to $50) off the subscription cost. Parents who purchase a subscription for use with their own child must pay the full subscription price, even if their child's school is registered for the MATHCOUNTS Competition Series.
 

Is it possible to cancel an OPLET subscription and receive a refund?

Due to the nature of OPLET and its 12-month subscription, mid-year cancellations are not permitted.
 

How do I give OPLET access to other teachers at my school?

Up to 6 teachers from the same school may share a single OPLET subscription, but the primary subscriber must submit a Multiple User Authorization Form to MATHCOUNTS. Teachers from neighboring schools (for example, 2 schools in the same district) may not share a single subscription. Parents and other non-teachers are only eligible to be considered additional users for a school's account if they actively participate in coaching the school’s MATHCOUNTS team.
