**powerful math interaction**into your learning environmentOur widgets handle student input, formative support and scoring.
They are the building blocks that make your math questions interactive.
Click on an interaction type to see it in action or solve an exercise yourself!

**Interaction types**

Multistep Derivation

The best-known (and for many students the most difficult) activity of mathematics, is the
step by step rewriting of mathematical expressions. AlgebraKiT evaluates every intermediate step and supports with hints
and feedback, regardless of the solution strategy chosen by the student.

Inline Math

For questions that do not require extensive derivations, we offer a widget that can be used inline
with the surrounding text. Do not mistake its tiny dimensions for insignificance. It features the same formula editor, formative feedback
and automatic scoring as the Multistep Derivation.

Math Table

Tables are used frequently to analyse relations, to prepare graphs or to just organize expressions.
AlgebraKiT evaluates the input against the underlying relations, which allows for automatic hints and error analysis.

Arithmetic Notebook

An advanced widget for context-rich arithmetic exercises. Designed for exercises that require
the student to translate a 'practical' situation into a mathematical problem, solve the problem and interpret the result.

This interaction features step-by-step evaluation, hints and feedback and a progress indicator. Also a ratio table is included.

Multiple Choice

The well-known question type, extended with randomization and display mathematical content as formulae and graphs.

Open Math Answer

A widget for questions that require an answer in natural language, often mixed with mathematical expressions.
Although automatic evaluation is not possible, it features a convenient formula editor to be able to handle the question entirely from
the online learning environment.

Long Arithmetic

A widget for solving arithmetic problems in primary education, much like pen and paper. The question
type supports various types of addition, subtraction and multiplication. Division will follow soon.

Presentation widgets

AlgebraKiT also offers some widgets to display mathematical concepts.

Multistep Derivation View

A worked-out solution of a Multistep Derivation, generated automatically by AlgebraKiT. The user can
hover or click the steps to see more detailed information.

Graph View

A graph generated from its defining formula and domain. A proper choice of axis ranges and ticks is made
automatically by AlgebraKiT. Use this graph for example to offer randomized exercises, showing a different graph each time.
