Here is a quick overview of the math related functionalities in Grasple: 

Computer Algebra System

The essential feature of a math homework system: the Computer Algebra System (CAS). This system can compare mathematical answers to determine if they are equivalent. 

For example: correct answer: 2x+2. Student types: 2(x+1), which is automatically marked correct. 

Special checks

Sometimes, you want students to write the answer in the final form. For example: ½ instead of 2/4. This can be easily achieved with our “exact form check”.

Also, in certain areas in math, there are often infinitely many correct solutions. For example in Linear Algebra. Grasple contains multiple specialised checks, so that all answers that are correct, are recognised as being correct. (more info in this help guide

Math editor and LaTeX support 

Quickly create math exercises (with symbols, integrals, matrices)
by using a) the visual editor b) write LaTeX. (more info in this help guide

Parametrisation

In math, you have to practice. With parameterization, you can quickly create variations of the same exercise, changing the numbers every time. (more info in this help guide)

Operators

Save time creating exercises by using the Computer Algebra System (CAS) to create questions. Instead of manually having to type the formules, you can use the operators. For example, use the determinant operator on a matrix and obtain the result right away. (more info in this help guide) 

(Interactive) Graphs

Generate 2d graphs of multiple parameterized functions. Coming soon (in coming weeks).

Also on our roadmap: creating interactive graphs, where students can interact with the graphs using a slider. (See a working example of interactive graphs in this lesson on Taylor polynomials

Specific feedback

Provide specific feedback to common misconceptions by using answer rules. Using this feature, it also possible to provide feedback based on characteristics of the student’s answer.
